## Summary description

Monomode fiber optic patch cable TECHLY with ST connector on one end and LC on the other. 3 m length, 9/125 µm OS2 singlemode fiber, full duplex for bidirectional links. Suitable for telecommunications, data centers and networking equipment requiring low‑loss long‑distance singlemode connections.

## Long description

TECHLY fiber optic patch cable ST to LC, monomode OS2 9/125, 3 m duplex is a single‑mode patch cord designed for low‑loss, long‑distance optical links. The cable combines an ST connector on one end with an LC connector on the other, in a duplex configuration that supports bidirectional transmission up to typical single‑mode distances. With a 9/125 µm core/cladding geometry and OS2 specification, it is intended for telecommunication, data center and backbone network connections where single‑mode performance is required.
Advantages
This TECHLY ST to LC single‑mode cable provides the optical characteristics of OS2 fiber with a 9 µm core and 125 µm cladding, offering low attenuation for longer runs. The duplex design enables full duplex links without additional adapters, and the LC/ST connector pair ensures compatibility with equipment using compact LC ports and legacy ST interfaces. The cable jacket and construction are optimized for standard installation environments, offering consistent performance for high‑speed links such as 10 Gbit/s applications.
Suitable for
Telecommunication links between buildings and floors
Data center horizontal and backbone connections
Network equipment interconnects requiring LC and ST ports
Long‑distance single‑mode runs and campus networks

How to use
Inspect connector endfaces for cleanliness before installation and clean with appropriate fiber cleaning tools if necessary. Connect the ST end to equipment or patch panel ports accepting ST plugs and insert the LC end into the corresponding LC receptacle. Ensure duplex polarity is correct for transmit/receive pairing. Avoid tight bends and secure the cable along its run to prevent stress; follow standard fiber handling practices during routing and termination to maintain optical performance.
Usage recommendations
Use this monomode OS2 duplex patch cable for point‑to‑point and patch panel connections in telecommunications and data center environments. Maintain recommended bend radius and keep connector endfaces protected when not in use. For optimum performance in long‑distance or high‑speed links, verify link loss budgets and clean connectors prior to commissioning.
