1m OM1 Fibre Optic Cable LC-ST 62.5/125
A 1m duplex OM1 fibre patch lead with LC connectors at one end and ST at the other. Duplex means two fibres, one to send and one to receive, so a single lead connects a pair of ports.
OM1 is 62.5/125 multimode fibre, found in many older installations. It carries Gigabit Ethernet up to about 275m and 10 Gigabit up to about 33m, so it is mostly used to extend or repair existing OM1 links.
LC plugs are small push-and-latch connectors used on SFP and SFP+ transceivers, modern switches and high density patch panels, while ST plugs are round bayonet connectors with a twist lock, common on older multimode equipment and patch panels. A lead like this joins LC equipment to ST equipment without an adapter.
A 1m lead keeps patching tidy inside a single rack, with no spare fibre to coil. Avoid bending it tighter than 60mm, as sharp bends weaken the signal and can damage the fibre. The LSZH (low smoke zero halogen) jacket suits offices, data centres and public buildings.
