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.

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 Both statements are printed, neither is withdrawn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

  • 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.

On the listing

A copper ten-gigabit transceiver, 10GBASE-T, presenting an RJ45 socket in an SFP+ cage, for cable described as CAT6A, CAT7 or CAT8, with a reach of up to 30 m; a Realtek controller named as the newest chip and credited with a performance improvement; plug and play and hot-pluggable operation, with the ring latch turned ninety degrees down to release it; compatibility for Cisco SFP-10G-T-S with the Cisco Nexus and Cisco Meraki series excluded, and for Ubiquiti UF-RJ45-10G, Ubiquiti Networks, Netgear AXM765, DEM-440XT, Mikrotik, Supermicro and other open switches; a statement that every module was checked individually on various switches before shipping; and a thirty-day return, a two-year warranty and lifetime technical support.

Two cable categories, one sentence apart

The second bullet asks for two different things in a row. Sentence one: a copper module for CAT6A, CAT7 and CAT8 cable. Sentence two: supports the ten-gigabit rate for the use of Cat 5e cable or better.

Those are not the same requirement. The first is a narrow window at the top of the category range; the second opens the window several categories wider. Nothing between them explains the change — no shortened distance for the lesser cable, no note, no qualifier.

This page reports both because both are published. What it will not do is choose the sentence that reads better and present it as the specification. The one number that might have reconciled them, a reduced reach on lower-category cable, is not on the page either: the title says up to 30 m and says it once.

The exclusions in the fourth bullet

Now the part that is genuinely good, and it is the only one of its kind in this hub.

The fourth bullet names Cisco SFP-10G-T-S and then, in the same breath, rules out the Cisco Nexus series and the Cisco Meraki series. A seller who writes that has tried it and found where it stops.

Compare that with the alternative style, which is a list of brand names and a hope. Naming an exclusion costs a seller sales and buys a buyer certainty, and there are six other listings on this shelf that never do it.

No operating temperature on a copper SFP+

Copper ten-gigabit modules work hard. The circuitry that drives 10GBASE-T down a twisted pair sits inside a sealed metal cage with a switch chassis around it, and it turns electricity into heat while it does so.

This page publishes no operating temperature, no ambient recommendation and no power figure. The other copper module on this shelf publishes both a draw and an ambient limit, which is the comparison that makes the silence here visible rather than merely unremarkable.

Before ordering

Put the cable question to the seller in writing, because the page asks for two different categories and the answer decides whether the run in your wall qualifies. Check your switch against the fourth bullet, which is unusually specific about where it fails. And if the cage sits in a closed cabinet, plan for a module whose thermal behaviour is nowhere described.

  • 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

  • QINIYEK 10GBASE-LR single-mode SFP+ transceiver with a duplex LC optical port

    QINIYEK 10GBASE-LR single-mode SFP+, 1310 nm, 10 km stated, four to a pack

    The only multi-module pack on this shelf, four ten-gigabit single-mode transceivers in one order, sold with the lowest published power draw here and a first bullet that manages to describe the same fibre two incompatible ways.

    Module form factor
    SFP+ — stated in the title, sold four to a pack, which no other listing on this shelf does
    Module rate
    10 G — stated in the first bullet as the data rate, and carried by the 10GBase-LR designation in the title
    Optical or copper medium
    Optical — the first bullet names a duplex LC connector and single-mode fibre, and the second lists the switch families it is coded against
    Fibre type
    Single-mode — SMF is stated in the title and in the first bullet. The same bullet then gives the 10 km reach as obtained with a multimode fibre cable, OS2. The two halves of that sentence do not agree; the rest of the listing — SMF, 1310 nm and the 10GBASE-LR designation — reads single-mode throughout, and the page never reconciles them
    Stated reach
    Up to 10 km — stated in the title and in the first bullet, in the same line as the fibre description that contradicts itself
    Connector type
    Duplex LC — stated in the first bullet as the interface, so each link uses two strands
    Wavelength
    1310 nm — stated in the title and in the first bullet
    Vendor coding stated
    Coded for Cisco SFP-10G-LR, Ubiquiti UF-SM-10G and Meraki MA-SFP-10GB-LR, with Mikrotik, D-Link, Supermicro, Netgear and other open switches named in the second bullet without part numbers
    Operating temperature range
    Not published on the listing — no range appears in any bullet. The third publishes a power consumption of less than one watt and low EMI in its place, and adds that every module is checked individually before packing

    • Four modules in one pack, which is two complete links rather than one end of one
    • Under one watt, the lowest power figure published on this shelf
    • The first bullet calls the fibre multimode and SMF in a single sentence

    Best for: Two ten-gigabit single-mode links being built at once, or one link with spares, into switches whose module lists name the Cisco, Ubiquiti or Meraki part numbers quoted.

  • TP-Link TL-SM311LM multimode gigabit SFP module with an LC optical port

    TP-Link TL-SM311LM, multimode gigabit SFP, 850 nm, 550 m stated

    The module of a switch maker sold for other makers’ switches, with the shortest specification on this shelf: a wavelength, a distance and an LC socket, plus a storage temperature standing where an operating one should be.

    Module form factor
    SFP, named a MiniGBIC in the first bullet — the gigabit cage. The second bullet places it on a switch with SFP ports
    Module rate
    Gigabit — stated as such in the title, with the first bullet calling it a multi-mode MiniGBIC module. No figure in megabits or gigabits per second is printed anywhere on the page
    Optical or copper medium
    Optical — multi-mode, stated in the title and in the first bullet, with the second naming enterprise fibre networks, campus fibre networks and ISP networks as its use
    Fibre type
    Multimode — stated in the title and in the first bullet. The grade is not published on the listing: no OM1, OM2, OM3 or OM4 designation appears, and the third bullet gives 550 m at 850 nm in its place
    Stated reach
    550 m — stated in the title as a reach of up to 550 m, and in the third bullet as a transmission distance of 550 m
    Connector type
    LC — stated in the title as an LC interface. Whether that is a duplex pair or a single position is not published on the listing, and no bullet returns to the subject
    Wavelength
    850 nm — stated in the third bullet, in the same line as the distance
    Vendor coding stated
    Not published on the listing — the title claims compatibility with Cisco, Meraki, Ubiquiti and Mikrotik, and no coding, no part number and no module list is named against any of them. This is a switch maker’s own module, offered for other makers’ switches
    Operating temperature range
    Not published on the listing — the fourth bullet publishes a storage temperature of -40 to 85 °C, an operating humidity of 10 to 90 % relative and a storage humidity of 5 to 90 % relative, and never the temperature the module is meant to work at

  • 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

  • akku-net black sealed lead-acid replacement battery of 12 V for an APC Smart-UPS

    akku-net Replacement cell for APC Smart-UPS 750, 12 V, 7.2 Ah / 86 Wh, 151 × 65 × 94 mm, 4920 g

    A cell whose specification bullet reads like a data sheet — voltage, capacity, watt-hours, cell type, three dimensions, weight and colour — and which still leaves the terminals entirely undescribed.

    Cell reference
    Not published on the listing — no cell code appears in the bullets. The reference carried in the record is the same string as the product barcode, and this page reports it as the record holds it rather than substituting anything else
    Cartridge reference
    Not published on the listing — no APC cartridge code appears anywhere. The title names the machine instead, as the APC Smart-UPS 750
    Voltage rating
    12 V — stated in the title and first in the specification bullet, which opens on voltage
    Amp-hour rating
    7.2 Ah — stated in the specification bullet, with 86 Wh printed immediately beside it. Both are the maker’s figures and both are reported here as printed; the watt-hour number is published rather than derived by this page
    Terminal type
    Not published on the listing — the specification bullet runs through voltage, capacity, cell quality, cell type, dimensions, weight, colour and compatibility, and never reaches the terminals
    Terminal width
    Not published on the listing — no millimetre figure for the tabs appears, which follows from the terminal type being absent
    Case dimensions
    151 mm × 65 mm × 94 mm — stated in the specification bullet. It is the same footprint two other cells on this shelf publish at the same rating
    Cells per pack
    Not published on the listing — no count appears, and no series or parallel arrangement is described. The bullets speak throughout of a single battery
    Assembled or loose supply
    Not published on the listing — nothing says whether an interconnect is fitted or the tabs arrive insulated. The fourth bullet describes the replacement as something the owner carries out, without describing what arrives
    Stated design life
    Not published on the listing — no period and no condition is given. The second bullet calls the cell maintenance-free and names power supply, standby installations and security and alarm equipment as its intended uses

    Fiamm Replacement cell for APC Back-UPS ES 700, 12 V, 7200 mAh / 86.4 Wh, 151 × 65 × 94 mm

    One of two cells on this shelf whose maker publishes the watt-hour figure itself, and the only one that gives its capacity in milliamp-hours rather than amp-hours.

    Cell reference
    Not published on the listing — no code describing the cell type, its case format or its rating appears in the bullets. The record carries the maker’s order reference, which is what the model field above holds
    Cartridge reference
    Not published on the listing — no APC cartridge code such as the RBC family appears. The machine is named instead, as the APC Back-UPS ES 700, in the title
    Voltage rating
    12 V — stated in the title and in the third bullet
    Amp-hour rating
    7200 mAh — stated in the third bullet, in milliamp-hours rather than in amp-hours, with 86.4 Wh given immediately beside it. Both figures are the maker’s and both are reported here in the units the maker printed them in. The watt-hour figure is published rather than derived, which is why it appears at all
    Terminal type
    Not published on the listing — no Faston tab, no bolted post and no designation is named in any of the five bullets
    Terminal width
    Not published on the listing — no millimetre figure appears for the tabs. One cell on this shelf publishes a width and the other five do not
    Case dimensions
    151 mm × 65 mm × 94 mm — stated in the fourth bullet. Three cells in this hub carry exactly these three numbers, which is the standard footprint for a sealed cell of this rating
    Cells per pack
    Not published on the listing — no count and no series or parallel arrangement appears. The bullets describe a single battery without ever saying so in a number
    Assembled or loose supply
    Not published on the listing — nothing says whether an interconnect is fitted or the tabs arrive insulated. The first bullet calls it an original battery and the second calls it high-grade new stock
    Stated design life
    Not published on the listing — no period and no conditions are given. The fifth bullet claims cells of the highest quality, which is a claim rather than a specification
