Good Connections Fiber Optic Patch Cable OM4 Multimode 50/125, SC to ST Duplex, LSZH 3mm, 10m, Violet

The Good Connections LW-810TC4 is a 10 m OM4 multimode duplex fibre patch cable with SC and ST connectors, made for short-reach multimode links between switches, servers, storage and patch panels.

It uses OM4 laser-optimised multimode 50/125 µm fibre in a LSZH jacket of 3 mm, colour-coded violet so the fibre type is recognisable in the rack. Every cable is 100% tested and ships with its own test protocol.

• 1 × fibre optic patch cable
• Dust caps fitted on the connectors
• Individual test protocol (each cable 100% tested)

• Under IEEE 802.3, OM4 carries 10GBASE-SR up to 400 m and 25GBASE-SR up to 100 m, more headroom than OM3 for 40G/100G SR optics.
• Connectors: SC on one end, ST on the other — a hybrid cord for joining SC ports to ST ports. SC: SC (square push-pull connector, common on patch panels, media converters, older switches and FTTH equipment); ST: ST (round bayonet connector, found on legacy patch panels and older campus or industrial equipment).
• Length: at 10 m it reaches between racks or across a server room.
• Polarity can be swapped on the duplex clip (not on the ST end) — if the link stays dark, reverse A/B at one end instead of buying another cable.
• LSZH jacket: low smoke and zero halogen when exposed to fire — the jacket normally required in offices, data rooms and public buildings.

• Single-mode optics (10GBASE-LR, 1000BASE-LX, BiDi LR, GPON) — they need OS2 single-mode fibre; a multimode cord will not give a reliable link.
• Ports other than SC and ST — the ends do not fit other connector types without a hybrid cord or adapter; check both ends of your link before ordering.
• Single-fibre BiDi optics with a simplex port — they take one fibre; use a simplex cord there.
• RJ45/copper ports — this cable carries light, so both ends need fibre ports or optical transceivers.
