Publishes a power draw, an ambient limit and ten makers it will not work with

10Gtek 10GBASE-T copper SFP+, 30 m stated, Marvell AQR113C named, 2.5 W draw

The copper module that tells you what it costs in watts and where it gets too warm, and then prints ten maker names it will not work with — the only listing on this shelf that spends a bullet on its own limits.

10Gtek 10GBASE-T copper SFP+ module with an RJ45 socket and a metal shell

10Gtek 10GBASE-T copper SFP+, 30 m stated, Marvell AQR113C named, 2.5 W draw

The copper module that tells you what it costs in watts and where it gets too warm, and then prints ten maker names it will not work with — the only listing on this shelf that spends a bullet on its own limits.

Module form factor
SFP+ — stated in the title, and the first bullet asks that the transceiver be used in a 10G SFP+ port rather than a gigabit one
Module rate
10 Gb/s — stated in the first bullet as the data rate, and carried by the 10GBase-T designation in the title
Optical or copper medium
Copper — stated in the title, which calls it a copper transceiver with an RJ45 socket
Fibre type
Not published on the listing, and a copper module has no fibre to qualify. The second bullet names the cable instead: CAT.6a or CAT7 RJ45 cable, quoted in the same line as the reach
Stated reach
Up to 30 m — stated in the title and in the second bullet, in both cases against the Cat 6a or Cat 7 cable named beside it
Connector type
RJ45 — stated in the title as the socket the module presents
Wavelength
Not published on the listing, and copper carries none. The fifth bullet names the Marvell AQR113C PHY controller in its place and calls it the latest of its kind
Vendor coding stated
Compatibility is claimed for Cisco, Meraki, Ubiquiti except the US-48-500W, Mikrotik, Netgear, Zyxel, QNAP NAS, Synology, D-Link, TP-Link, Supermicro and other open switches. The fourth bullet then names ten makers it is not compatible with: HP-ProCurve, HP-H3C, HP-Aruba, Intel, Arista, Mellanox, Dell Force10, Extreme, Brocade and Juniper
Operating temperature range
Not published on the listing as a range — the fifth bullet states instead that the module can become hot in use because the integrated circuit draws 2.5 W, and recommends using it where the ambient temperature stays below 50 °C

  • The only listing here that publishes what the module draws, and says what that means in practice
  • Ten makers are named as incompatible, which is worth more than any list of the compatible ones
  • The thermal statement is an ambient recommendation, not the working range a datasheet would carry

Best for: A ten-gigabit copper link in a cabinet with air actually moving through it, into a switch outside the ten makers this listing rules out.

On the listing

A copper ten-gigabit transceiver, 10GBase-T, with an RJ45 socket in an SFP+ cage, a data rate of 10 Gb/s and a request that it be used in 10G SFP+ ports; a cable type given as CAT.6a or CAT7 RJ45 with a reach of up to 30 m; compatibility claimed for Cisco, Meraki, Ubiquiti with the US-48-500W excluded, Mikrotik, Netgear, Zyxel, QNAP NAS, Synology, D-Link, TP-Link, Supermicro and other open switches; a list of ten makers it is stated not to be compatible with; and a Marvell AQR113C PHY controller, with a note that the module can become hot in use because the integrated circuit draws 2.5 W, and a recommendation to use it where the ambient temperature stays below 50 °C.

2.5 watts inside a sealed cage

One number on this page explains the behaviour of an entire product category, and only one listing in this hub prints it. The integrated circuit draws 2.5 W.

That is what turning ten gigabits into voltages on a twisted pair costs. It is dissipated inside a metal shell with no airflow of its own, pressed against neighbouring cages in a switch that was designed around transceivers drawing a fraction of it.

The maker follows the figure with the sentence that matters: use it where the ambient temperature is below 50 °C. That is not an operating range, and this page does not pretend it is one. It is a recommendation, and it is the only thermal guidance anywhere on this shelf.

The ten makers named as incompatible

HP-ProCurve, HP-H3C, HP-Aruba, Intel, Arista, Mellanox, Dell Force10, Extreme, Brocade, Juniper.

A seller does not write that list for fun. Each name on it is a market being declined, and the reason is always the same: the switch reads a code, does not like what it reads, and either refuses the module or fills a log with complaints about it.

There is a second exclusion hidden in the compatible list, and it is finer still — Ubiquiti equipment generally, except the US-48-500W. A single model, carved out by name. That is the level of detail that comes from returns rather than from a datasheet.

Cat 6a or Cat 7, and 30 metres

The cable statement here is short and it does not contradict itself, which distinguishes it from the other copper module on this shelf.

CAT.6a or CAT7, up to 30 m. One requirement, one distance, printed together in the same bullet so that neither can be read without the other. Nothing is said about what happens on lesser cable, which is a gap rather than a conflict, and a buyer with Cat 6a already in the wall has everything the page owes them.

Before ordering

Check your switch against the fourth bullet before anything else — ten makers are ruled out by name, and three of them are HP families. Then think about where the cage sits: 2.5 W with no airflow is the reason this module comes with an ambient recommendation at all. And confirm the run is Cat 6a or Cat 7 over its full length, since that is the only cable this page will speak for.

More SFP modules

  • Elfcam pair of bidirectional 10G SFP+ transceivers with single SC optical ports

    Elfcam matched pair of bidirectional 10G SFP+, SC simplex, OS2, 20 km stated

    The dearest listing on this shelf and the only one that ships a complete link: two bidirectional modules with their wavelengths already reversed, on SC connectors where everything else here uses LC or RJ45.

    Module form factor
    SFP+ — stated in the title, supplied as one pair of two modules rather than as a single transceiver
    Module rate
    10 Gbps, 2.5 Gbps and 1.25 Gbps — three rates stated in the second bullet, with 10 Gb, 2,5 Gb and 1,25 Gb also named in the title
    Optical or copper medium
    Optical — the first and second bullets name a single-mode simplex SC fibre port of 9/125 µm
    Fibre type
    Single-mode, 9/125 µm — stated in the title and again in the first, second and fourth bullets. The grade is given as OS2 in the title and in the first and fourth bullets, which makes this one of only two optical modules on this shelf to name a grade at all
    Stated reach
    Up to 20 km — given in the first bullet as 20 KM and in the fourth as a transmission distance of up to 20 km with a single-mode simplex 9/125 µm OS2 SC cable
    Connector type
    SC simplex — stated in the title and in the first bullet. It is the only SC module on this shelf; the other six take LC or RJ45
    Wavelength
    TX 1270 nm with RX 1330 nm on one module and TX 1330 nm with RX 1270 nm on the other — stated in the first and second bullets. That reversal is what makes the pair a pair, and it is the reason the two modules are not interchangeable with each other
    Vendor coding stated
    Coded for Cisco SFP-10G-BXD-I and SFP-10G-BXU-I — the downstream and upstream halves named separately — with Ubiquiti Networks UF-SM-10G-S, Huawei, D-Link, Ruijie and open switches added in the third bullet, which prints Huawei twice
    Operating temperature range
    Not published on the listing — no range appears in any bullet. The fifth offers a warranty and a repair service centre in Paris in its place, and the sentence that should give the warranty length has no number in it: it reads as a warranty period of years, with the figure missing

    B0DBLFC335 (same reference on 6 Amazon marketplaces)
    EAN
    3701528726041
    • Two modules with the wavelengths already reversed, so a single-strand link is complete in one order
    • Names both halves of the Cisco bidirectional pair, downstream and upstream, by part number
    • The warranty sentence has a blank where its number should be

    Best for: A 20 km single-strand run on SC-terminated single-mode fibre, bought once with both ends of the link in the same box.

  • GIQITCK 10GBASE-T copper SFP+ transceiver with an RJ45 socket

    GIQITCK 10GBASE-T copper SFP+ to RJ45, 30 m stated, Realtek controller named

    The cheaper of the two copper ten-gigabit modules here, sold with an unusually specific compatibility bullet that excludes two Cisco series by name and a cable requirement stated twice in two incompatible ways.

    Module form factor
    SFP+, called a mini-GBIC in the title — the ten-gigabit cage. The third bullet says it belongs in a 10Gb SFP+ port and names fibre switches, routers, network cards and servers as its hosts
    Module rate
    10 Gbps — stated in the title as 10GBASE-T and in the second bullet, which says the module supports a 10 Gbps rate
    Optical or copper medium
    Copper — stated in the title and in the second bullet, which calls it a 10G copper module with a copper RJ-45 plug
    Fibre type
    Not published on the listing, and a copper module has no fibre to qualify. What the second bullet names in its place is the cable, and it names it twice: Cat 6A, Cat 7 or Cat 8 in one sentence, then Cat 5e or better in the next. Both statements are printed, neither is withdrawn
    Stated reach
    Up to 30 m — stated in the title. No shorter distance is quoted against a lesser cable, which is what would normally reconcile the two cable statements
    Connector type
    RJ45 — stated in the title and in the second bullet as a copper RJ-45 plug
    Wavelength
    Not published on the listing, and copper has none. The nearest the page comes is the first bullet, which names a Realtek controller as the newest chip and credits it with a performance improvement
    Vendor coding stated
    Coded for Cisco SFP-10G-T-S, with the Cisco Nexus and Cisco Meraki series excluded by name in the same bullet; also named are Ubiquiti UF-RJ45-10G, Ubiquiti Networks, Netgear AXM765, DEM-440XT, Mikrotik, Supermicro and other open switches
    Operating temperature range
    Not published on the listing — no working range appears in any bullet. The fifth says instead that every module was checked one after another on various switches before shipping, and the sixth offers a thirty-day return, a two-year warranty and lifetime technical support
    Amazon reference
    B0DLG7WG35 (same reference on 6 Amazon marketplaces)
    EAN
    0717325593611
    • Names two switch series it will not work in, which no other listing on this shelf does
    • Quotes Cisco, Ubiquiti and Netgear part numbers rather than brand names alone
    • Two different cable requirements sit one sentence apart and neither is withdrawn

    Best for: A ten-gigabit copper run of up to 30 m into a switch on the named list, and specifically not into a Nexus or a Meraki.

  • QSFPTEK gigabit SFP transceiver with a duplex LC optical port and a metal body

    QSFPTEK 1000BASE-LX/LH single-mode SFP, 1310 nm, 10 km stated, coded for three HP part numbers

    The cheapest module on this shelf and the only one that publishes how much light leaves it and how little can arrive at the far end, sold coded for three HP part numbers with a request to confirm the switch before ordering.

    Module form factor
    SFP, called a mini-GBIC in the title — the gigabit cage rather than the larger SFP+ one. The fifth bullet lists the other form factors the seller stocks, from GBIC and SFP through SFP BIDI, DWDM and CWDM to 10G XFP, 10G SFP+ and 40G and 100G transceivers
    Module rate
    1000 Mbit/s — stated in the second bullet, and carried by the 1000BASE-LX/LH designation printed in the title
    Optical or copper medium
    Optical — the second bullet names a single-mode duplex LC connector, and the first places the module in fibre switches, routers, network cards and servers with gigabit SFP ports
    Fibre type
    Single-mode — stated in the title and again in the second bullet. The grade is not published on the listing: no OS1 or OS2 designation appears anywhere, and the maker gives a wavelength and a distance in its place
    Stated reach
    Up to 10 km — stated in the title and repeated in the second bullet as a transmission distance
    Connector type
    Duplex LC — stated in the second bullet, so the link uses two strands, one in each direction
    Wavelength
    1310 nm — stated in the title and in the second bullet, with a transmit power between -9 and -3 dBm and a receive sensitivity below -22 dBm quoted alongside it
    Vendor coding stated
    Coded for HP J4859A, J4859C and J4859B — stated in the title and in the first bullet, which adds other open switches without naming them. The fifth bullet asks the buyer to confirm the switch model before ordering, which is a seller declaring a coding rather than a switch maker certifying one
    Operating temperature range
    0 to 70 °C — stated in the second bullet as the working temperature, alongside the two optical power figures
    Amazon reference
    B07QR9HGMZ (same reference on 5 Amazon marketplaces)
    EAN
    0767912359670
    • Publishes transmit power and receive sensitivity, which no other module on this shelf prints
    • Names three HP part numbers outright instead of claiming compatibility in general terms
    • The fibre grade is never written, so OS1 and OS2 are left for the buyer to settle

    Best for: A gigabit link between two buildings on single-mode fibre, into a switch whose published module list names one of the three HP part numbers quoted.

Others worth having spare

  • Pyle PDBC70EU 19-inch rack power strip with six front switches and six rear sockets

    Pyle PDBC70EU, 6 rear sockets with front switches, mains filter named, 1.83 m lead, about 5.3 cm high

    Six sockets on the back and six switches on the front, in a metal case whose listing says plainly that it does not fit one rack unit — with the surge protection named and never given a number.

    Joule rating
    Not published on the listing — no joule figure appears in the title or in any of the five bullets. The second bullet names integrated surge protection and a mains filter and gives no figure for either
    Clamping voltage
    Not published on the listing — no voltage protection rating and no clamping level appears anywhere
    Response time
    Not published on the listing — no figure in nanoseconds and no timing of any kind is given
    Standards named
    Not published on the listing — no surge standard is named. The cable is described by its cross-section, at 3 × 1.5 mm², which is a construction figure rather than a standard
    Outlet count
    Six — stated in the title and in the first bullet, as six earthed sockets on the rear panel, each individually switchable from a switch on the front. It is the lowest outlet count on this shelf and the only one where every socket has its own switch
    Outlet spacing
    Not published on the listing — no distance between sockets is given. The sockets are on the rear and the switches on the front, which is an arrangement rather than a spacing
    Protected line types
    Mains only — no telephone, coaxial or network line is named. The second bullet names an AC noise filter alongside the surge protection, described as reducing interference, hum and voltage spikes for mixing desks, audio interfaces, amplifiers and power supplies
    Cable length
    1.83 m — stated in the fourth bullet, at 3 × 1.5 mm². It is the shortest lead published on this shelf
    Status indicators
    Not published on the listing — no protection status light is named. What the first and third bullets publish instead are front-panel switches, one per socket, which report and control the supply rather than the state of the protection

    • A switch for every socket on the front panel, which no other strip on this shelf offers
    • States its own height at about 5.3 cm and says outright that it is not exactly 1U
    • No joule rating, no clamping voltage and no response time

    Best for: A studio or stage rack where individual pieces of equipment need switching on and off from the front without anybody reaching round the back.

  • APC APCRBC123 sealed replacement battery cartridge in its APC packaging

    APC APCRBC123 replacement battery cartridge, sealed lead, tool-free change, 1-year warranty

    The most expensive product on this shelf publishes no voltage, no capacity, no terminal and no case size. Its entire specification is a part number, and for a machine maker’s own cartridge that is very nearly enough.

    Cell reference
    Not published on the listing — no code for the cell or cells inside the cartridge appears, and no rating is given for them
    Cartridge reference
    APCRBC123 — stated in the title, and it is the whole identity of the product. It is the maker’s own cartridge code, which is the reference APC publishes against each of its UPS models, and the fourth bullet says original RBC cartridges are checked and certified for compatibility to restore the machine’s original performance specifications
    Voltage rating
    Not published on the listing — no volt figure appears in the title or in any of the five bullets. It is the only listing on this shelf that publishes no voltage
    Amp-hour rating
    Not published on the listing — no amp-hour and no watt-hour figure appears anywhere. Five of the six listings in this hub publish a capacity, and this is the one that does not
    Terminal type
    Not published on the listing — no tab, post or designation is named. The third bullet says the battery can be changed without tools, which describes the operation rather than the connection
    Terminal width
    Not published on the listing — no millimetre figure appears, which follows from the terminal type being absent
    Case dimensions
    Not published on the listing — no length, width or height is given anywhere on the page
    Cells per pack
    Not published on the listing — the product is described as a cartridge and the number of cells inside it is never stated
    Assembled or loose supply
    Assembled, as a cartridge — the product name says so and the fifth bullet lists the contents as the battery, a recycling manual and installation instructions. The third bullet adds that the change is possible without tools
    Stated design life
    Not published on the listing — no design life and no conditions appear. What the second bullet publishes instead is a one-year repair or replacement warranty, which is a commercial term and not a statement about how long the cells are specified to last

  • EMOS B9674 sealed lead-acid AGM battery of 12 V and 7.2 Ah with Faston terminals

    EMOS B9674 AGM cell, 12 V, 7.2 Ah, Faston 6.3 mm tabs, 151 × 65 × 94 mm

    The one cell on this shelf whose title carries every figure a fitting decision needs: voltage, amp-hours, tab type, tab width in millimetres and all three case dimensions.

    Cell reference
    B9674 — stated in the first bullet in brackets, as EMOS B9674. It is the maker’s own code for the cell rather than a code belonging to any UPS
    Cartridge reference
    Not published on the listing — no UPS maker’s cartridge code appears, and no machine is named that the cell is sold as a replacement for. The title names the applications instead: UPS units, alarm systems
    Voltage rating
    12 V — stated in the title and in the second bullet. It is one of two figures on this page that must match what comes out of the machine, and the amp-hour figure is the other
    Amp-hour rating
    7.2 Ah — stated in the title and in the second bullet. The listing publishes no watt-hour product, and this page does not calculate one from the two figures printed here
    Terminal type
    Faston tabs — stated in the title. It is one of two listings on this shelf that names a terminal type at all
    Terminal width
    6.3 mm — stated in the title as a Faston 6.3 mm connection. No other listing on this shelf publishes a tab width in millimetres, and it is the figure that decides whether a cell of the right rating actually connects
    Case dimensions
    151 × 65 × 94 mm — stated in the title and again in the second bullet, which calls the format compact and suitable for a wide range of applications
    Cells per pack
    One — the title, the bullets and the contents all describe a single 12 V block. No pack count and no series or parallel arrangement is published
    Assembled or loose supply
    Loose — a single cell with no interconnect and no insulated tabs described. The first bullet adds that the AGM construction is leak-proof and that the cell can be used in any orientation
    Stated design life
    Up to 5 years — stated in the fourth bullet, alongside integrated safety systems and an instruction to charge the cell fully before first use. A design life is a manufacturer specification under stated conditions and is neither a warranty nor a prediction about one battery
