2m OS2 ST to SC Fibre Optic Cable Single Mode 9/125 Yellow
OS2 is 9/125 single mode fibre for long-distance links, carrying 1, 10 and 100 Gigabit Ethernet over kilometres rather than hundreds of metres with the right transceivers, and it is used between buildings, in campus backbones and for carrier connections.
This duplex lead has two fibres, one to send and one to receive, so it connects a pair of ports in one go. ST connectors have a round bayonet fitting that twists to lock, found on many established fibre installations, while sC connectors are square push-pull plugs common on patch panels, media converters and older switches. The connectors have a UPC (ultra physical contact) polish for low back-reflection. The LSZH (low smoke zero halogen) jacket suits offices, data centres and public buildings.
A 2m lead reaches between neighbouring racks or from a patch panel to equipment across a comms room. Single mode leads need single mode transceivers; they cannot be used with multimode optics.
