OM3 ST-SC Multimode Duplex Fibre Patch Lead

A duplex OM3 fibre lead with ST-SC connectors, made with laser-optimised 50 micron multimode (50/125) fibre. One fibre carries the transmit signal and the other the receive signal, the arrangement used by almost all fibre transceivers. It supports 10 Gigabit Ethernet up to 300 metres and 40/100 Gigabit (parallel optics) up to 100 metres. OM3 is a dependable all-rounder for server rooms, comms cabinets and building backbones, and works with OM4 links as both use a 50 micron core.

ST uses a round bayonet twist-lock, still found on many established fibre installations. SC is a square push-pull connector, common on older switches, media converters and fibre wall outlets. This lead joins the two types without a separate adapter. Aqua is the standard jacket colour for laser-optimised multimode fibre. Violet jackets are handy for colour-coding separate systems or customers in a shared rack.
