3m OM4 LC ST Multimode Fibre Network Cable 50/125
A 3m duplex OM4 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.
OM4 is a higher grade of laser-optimised 50/125 multimode fibre, carrying 10 Gigabit up to about 400m and 40/100 Gigabit up to about 150m. It gives more headroom than OM3 for data centres and longer runs.
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.
At 3m it links a patch panel to a switch or server in the same or the next rack. The LSZH (low smoke zero halogen) jacket suits offices, data centres and public buildings.
