On the listing

Five duplex OM4 multimode fibre patch cables of 2 m, 50/125 µ, LC to LC, in violet; an OM4 fibre said to offer higher transmission rates than OM1, OM2 and OM3, compatible with OM3, OM5 and short-wave division multiplexing, at wavelengths of 850 nm and 1300 nm; a bandwidth table giving 100 Gbit/s at 150 m under 100G BASE SR10, 40 Gbit/s at 150 m under 40G BASE SR4, 25 Gbit/s at 100 m under 25G BASE SR-S, 10 Gbit/s at 400 m under 10G BASE SE-SR and 1 Gbit/s at 550 m under 1000BASE-SX; an outer sheath of halogen-free LSZH material with flame-retardant behaviour; ceramic ferrules with dust caps, anti-kink boots and fibre marking, an insertion loss of 0.30 dB or less and a return loss of 30 dB or better with UPC named beside it; and an individual test report supplied with every lead.

OM4, and the five rates it is quoted against

No other listing on this shelf publishes a table like the one in the second bullet.

Five rates, each with its own distance, each with the ethernet standard it belongs to written out beside it. A hundred gigabit at 150 m. Forty at 150 m. Twenty-five at 100 m. Ten at 400 m. One at 550 m.

Read it and the shape of multimode becomes obvious: distance falls away as the rate climbs, and it falls away steeply. The same glass that carries a gigabit half a kilometre carries a hundred gigabit less than a third as far.

None of it applies to a 2 m lead, and that is not the point. The table is how a buyer decides whether OM4 is the right grade for the cabinet at all, and it names the standards rather than leaving the reader to match rates to designations.

Five leads in one box

This is a pack rather than a lead, and it changes what the purchase is for.

A single fibre lead is a link. Five identical 2 m leads are a patch field — a switch and a patch panel wired across in one afternoon, with a spare left in the drawer. Anyone joining two SFP+ cages once should buy something else; anyone populating a cabinet has exactly the right order here.

The other pack on this shelf is the four-pack of transceivers, and the pairing is not a coincidence: this is equipment for the kind of job that needs several of everything.

The measurement report in the packet

The fifth bullet says every lead ships with its own test or measurement protocol, because all of them go through a quality control after production.

That is a different claim from a specification. A specification describes what the design is meant to do; a measurement report describes what this piece actually did before it was boxed. When a link later runs badly, the report is what separates a lead that left the factory out of tolerance from one that has been trodden on since.

Two listings in this hub say they supply one. This is the one that supplies five.

The line that is missing on five leads at once

Polarity. The fourth bullet names a fibre marking and never says what the marking says.

On a duplex lead, the pair has to arrive the right way round or the transceivers talk past each other, and the listing that solves this properly — further along this shelf — embosses A and B into the clip and says so. Here there is a marking of some kind, described in three words, on five leads in one box.

It is a small job to sort out with a tester and an adjustable clip. It is a smaller job still when the page tells you.

Before ordering

Confirm the run is multimode, since five of the seven leads on this shelf are single-mode and the two families do not interchange. Check the polish at the far end: these are UPC, and a UPC face cannot be mated to an angled one. Then decide whether you want five — the per-lead economics only work if the fifth one gets used.

More fibre patch cables

  • Elfcam long simplex fibre patch cable with green LC/APC connectors at both ends

    Elfcam 30 m simplex OS2 LC/APC to LC/APC, 9/125 µm, 7.5 mm bend radius

    The longest lead in this hub by a wide margin, published with a bend radius and a bend-tolerant fibre conformity — and with two of its own descriptions at odds, on the jacket colour and on the jacket material.

    Fibre type
    Single-mode, 9/125 µm — stated in the title and in the first bullet, which describes the lead as running between a fibre termination point and an ONT
    Fibre grade
    OS2 — stated in the first and fourth bullets, with conformity to G.657.A2 and B2 named in the first and a minimum bend radius of 7.5 mm given immediately beside it
    Connector types at each end
    LC/APC at both ends — stated in the title and in the first bullet, and the fourth adds that every lead is supplied with dust caps
    Simplex or duplex
    Simplex — stated in the title and in the first bullet. One strand, one connector at each end
    Polarity arrangement
    Not published on the listing, and a simplex lead has no pair to cross
    Length
    30 m — stated in the title twice over. The fifth bullet gives the range the lead is sold in, from 0.5 m to 100 m
    Jacket rating
    LSZH — stated in the first bullet. The third then describes the outer sheath as a halogen-free, flame-retardant copolymer and names an inner sheath of PVC, which is the only mention of PVC on the page and sits awkwardly beside the LSZH claim
    Polish type
    APC — carried by the LC/APC designation at both ends. No angle, no insertion loss and no return loss figure is published; the fourth bullet says instead that leads are individually packed and supplied with a measurement report
    Armouring
    Not published on the listing — the third bullet names a filled loose tube and non-metallic strength members, which is a construction rather than an armour, and describes the lead as an indoor cable for laying inside buildings

    • Thirty metres, the longest lead on this shelf by a wide margin
    • A minimum bend radius is printed, which matters most on the longest run here
    • The jacket is white in the title and in the first bullet, and yellow in the fourth

    Best for: A long indoor run between a fibre termination point and a router at the other end of a flat, where 30 m of LC/APC is simply what the job needs.

  • FLYPROFiber aqua duplex OM4 fibre patch cable with LC connectors and A and B labelled clips

    FLYPROFiber 1 m duplex OM4 LC to LC, 50/125 µm, UPC polish, A/B labelled clips

    The only multimode lead here with a full reach table behind it — four rates, four distances, all at 850 nm — and the only one on this shelf whose duplex clip is marked A and B so a cabinet can be read at patching time.

    Fibre type
    Multimode, 50/125 µm — stated in the title and in the third bullet, which calls the fibre insensitive to bending, easy to strip and easy to splice
    Fibre grade
    OM4 — stated in the title and in the first bullet, with a bandwidth of 2000 MHz·km at 850 nm given in the second. The first bullet calls OM4 the preferred fibre specification for 40G and 100G applications
    Connector types at each end
    LC at both ends — stated in the title and in the first bullet, which names 40G BIDI SR, 10G SR, QSFP+ and SFP+ transceivers as what it is meant to join
    Simplex or duplex
    Duplex — stated in the title as 40 GB/100 GB Duplex and in the first bullet as an LC-LC duplex patch cable
    Polarity arrangement
    Embossed A and B position labels on the duplex clip and on the marking ring — stated in the fourth bullet, whose stated purpose is quick identification of Tx and Rx during installation, testing and fault finding. Whether the pair is supplied crossed is not published on the listing; the same bullet names adjustable connector clips, which is how a pair is rearranged by hand
    Length
    1 m — stated in the title, which also gives the range the lead is sold in, from 0.2 m to 100 m
    Jacket rating
    LSZH — stated in the title and in the fourth bullet, which calls the jacket an environmentally friendly LSZH sheath
    Polish type
    UPC — stated in the fourth bullet as a high-grade UPC polish on zirconia ceramic ferrules made in Japan. The third bullet quotes an insertion loss of 0.3 dB or less and a return loss of 30 dB or better
    Armouring
    Not published on the listing — no armour is named. The third bullet gives a minimum bend radius of 7.5 mm instead, and offers the lead for cabinets requiring twenty or more bends and for high-density installations in very small spaces

    B09C224CLK (same reference on 5 Amazon marketplaces)
    EAN
    0649910317572
    • Four ethernet distances at four rates, all quoted at 850 nm, the fullest reach table on this shelf
    • A and B labels embossed on the clip and the marking ring, so Tx and Rx can be read by eye
    • The four distances belong to the fibre, and the lead in the bag is 1 m long

    Best for: A short OM4 hop between two SFP+ cages in the same cabinet, where the A and B labels earn their keep every time the patching changes.

  • HB-DIGITAL yellow duplex fibre patch cable with green LC/APC connectors at both ends

    HB-DIGITAL 1 m duplex OS2 LC/APC to LC/APC, 9/125 µm, LSZH

    The cheapest lead on this shelf and one of the best documented, with a sub-grade named, both loss figures printed and a connector standard cited by number — and no word at all about which way its two strands are arranged.

    Fibre type
    Single-mode, 9/125 µm — stated in the title and in the first bullet, which calls it a high-grade single-mode fibre patch cable
    Fibre grade
    OS2, with the sub-grade G657.A2 named in brackets in the first bullet. Three of the seven leads on this shelf qualify their grade with a G.65x designation and this is one of them
    Connector types at each end
    LC/APC at both ends — stated in the title and in the first bullet, which names the duplex connectors explicitly
    Simplex or duplex
    Duplex — stated in the title, and described in the third bullet as two 2.0 mm fibre lines in a stable parallel arrangement, quoted as 2 × 2.0 mm, said to suit applications with double or redundant connections
    Polarity arrangement
    Not published on the listing — nothing says whether the pair arrives crossed, and no A or B marking is described anywhere. The third bullet describes the parallel construction and stops there
    Length
    1 m — stated in the title. Three of the seven leads on this shelf are 1 m and this is one of them
    Jacket rating
    LSZH — stated in the title and in the fourth bullet, which spells out Low Smoke Zero Halogen and calls the material flame-retardant and low-smoke, suited to interiors, public buildings and technical installations
    Polish type
    APC — carried by the LC/APC designation at both ends. The first bullet quotes an insertion loss of 0.3 dB or less and a return loss of 60 dB or better, the highest return loss figure published on this shelf
    Armouring
    Not published on the listing — no armour, no steel braid and no rodent protection is named. The fifth bullet offers manufacture to IEC 61754-20, testing of every lead for insertion and return loss, and an operating range of -40 °C to +85 °C instead

    deleyCON Cat 6a shielded keystone jack, solid AWG 22-25, aperture 19.35 × 14.8 mm, pack of 4

    The one module in this hub that prints a dimension — a keystone aperture of 19.35 by 14.8 mm, which is the opening at the front and not the room behind it — and the one restricted to solid conductors alone.

    Category rating
    Cat 6a — stated in the title and the first bullet, with a maximum signal transmission of 500 MHz and support for 10 Gbit Ethernet and Power over Ethernet
    Termination method
    Toolless insulation-displacement, snap-in — stated in the first and second bullets as an RJ45 socket on one side and a toolless strip on the other, with the third bullet crediting the housing design with fast and secure contact without special tools. The fifth bullet gives the wire acceptance as solid conductor AWG 22 to 25, names no stranded range, and says the wiring order T568A and B is marked on the load piece itself
    Shielded or unshielded
    Shielded — stated in the title and the first bullet as STP, in a nickel-plated zinc die-cast housing
    Module depth
    Not published on the listing — the first bullet publishes a keystone opening of 19.35 by 14.8 mm, which is the aperture at the front. The dimension behind the plate, which is the one that decides whether a face plate sits flat, never appears
    Angled or straight body
    Not published on the listing — no exit angle is given. The fifth bullet says instead that the cable can be fed in through 180 degrees, which describes the approach rather than the body
    Colour options
    Not published on the listing — the only colour named is the T568A and B wiring order marked on the load piece
    Pack quantity
    Four — stated in the title
    Accessories included
    Not published on the listing — the fifth bullet describes the housing as one piece and reusable and says up to 24 modules fit a 1U panel of 483 mm, and nothing is named as supplied with them

  • DIGITUS Cat 6A shielded keystone module with an RJ45 socket and a plastic latch

    DIGITUS Cat 6A shielded keystone jack, AWG 26/7 to 22/1, single module

    The one module on this shelf sold singly rather than in fours or twelves, published with a conductor window that covers stranded and solid alike and with a certification named by the body that issued it.

    Category rating
    Cat 6A, Class EA — stated in the title and in the first and third bullets, with 500 MHz and up to 10 Gbit/s quoted, on the stated condition that the cable behind it is Cat 6A or higher
    Termination method
    Toolless insulation-displacement — stated in the third bullet as an installation needing no tool, for conductor cross sections between AWG 26/7 and 22/1. The fourth bullet adds that the strips are colour-coded to EIA/TIA 568 A and B
    Shielded or unshielded
    Shielded — stated in the title and in the first bullet, which names a 360-degree screen around the module
    Module depth
    Not published on the listing — no depth, height or length appears. The fourth bullet says instead that the module is design-compatible with common network outlets, which is a claim about the front and not about the room behind it
    Angled or straight body
    Not published on the listing — nothing says which way the cable leaves the back of the module, and no exit angle is quoted
    Colour options
    Not published on the listing — the only colour coding named is on the termination strips, to EIA/TIA 568 A and B, which is a wiring order rather than a choice of body finish
    Pack quantity
    One — stated in the title. It is the only single-module listing on this shelf
    Accessories included
    Not published on the listing — the fourth bullet describes a plastic latch on the top of the body and a GHMT certification, and names nothing supplied alongside the module

  • Germany B.e.s.t Cat 7 shielded keystone module with a full metal body

    Germany B.e.s.t Cat 7 shielded keystone jack, 1000 MHz stated, PoE++ to 100 W, pack of 4

    The only module here quoting a frequency above 500 MHz and the only one putting a wattage against PoE — and the one that publishes no conductor range at all, which is the line that decides what cable it will actually take.

    Category rating
    Cat 7 — stated in the title and the first bullet, with up to 10 Gbit/s, and an operating frequency of up to 1000 MHz in the fifth bullet. No class designation is printed beside either figure, so neither can be checked against the class the other five modules here name
    Termination method
    Toolless insulation-displacement — stated in the fourth bullet, which says no crimping and no special tool is needed and names patch panels, hollow-wall boxes and wall outlets as destinations. No conductor window accompanies it: neither a gauge nor a diameter nor a construction appears beside the strip anywhere on the page
    Shielded or unshielded
    Shielded — stated in the third bullet as a full metal body with an internal STP screen, offered against electromagnetic interference
    Module depth
    Not published on the listing — no dimension appears, on a module the fourth bullet offers for a hollow-wall box, which is the shallowest destination of the three it names
    Angled or straight body
    Not published on the listing — nothing says which way the cable leaves the body
