LC to ST OM3 Fiber Patch Cable – Duplex LC UPC to ST UPC, LSZH
LC to ST OM3 Fiber Patch Cable links LC-equipped multimode equipment to ST-terminated patch panels or distribution points. This duplex 50/125 µm assembly uses LC UPC connectors at one end and ST UPC connectors at the other, with an LSZH jacket for LAN and data center patching.
LC Equipment to ST Patch Panels
Use this mixed-connector assembly when the two ends of the link require different connector formats. The LC end fits matching LC interfaces, while the ST end uses a bayonet coupling at matching ST adapters. Check both ends of the patch route before selecting the cable.
Duplex OM3 for Multimode Links
Two fiber paths support transmit and receive connections in compatible duplex multimode systems. Match the OM3 50/125 µm fiber to the installed cabling and optics, and maintain the required transmit-to-receive polarity. The cable connects matching optical interfaces without converting the optical signal or fiber type.
LSZH Jacket and Five Standard Lengths
Choose 1, 2, 3, 5 or 10 m to suit the distance between equipment and patching points. The LSZH jacket is intended for installations specifying low-smoke zero-halogen cable. Allow service slack and route the patch cord without tight bends or connector strain.
