Extron 2LC SM P/50 (part number 26-670-50) — 50 metres (164 ft) of duplex LC singlemode fiber in a plenum-rated jacket. Extron has retired this length, so Ampronix carries it for replacement and expansion of existing 2LC SM P links.

Pulling 50 metres of fiber is a construction task, and the assembly is built accordingly. Two glass singlemode fibers share a PVC zip-cord jacket listed ETL and c-ETL to OFNP FT6, with aramid yarn running the length of the cable to carry pulling tension away from the glass. Both ends arrive from the factory with LC connectors polished to ultra physical contact, so the installer never has to expose a fiber end on site.

Key Capabilities

• 50 m (164 ft) continuous duplex singlemode assembly, factory terminated.
• Two glass fibers per cable, singlemode 8.3 µm.
• PVC jacket rated OFNP FT6 by ETL and c-ETL for plenum spaces.
• Attenuation kept under 0.5 dB per kilometre at 1310 nm and at 1550 nm.
• Aramid yarn strength members for a long, high-tension pull.
• Retired Extron length — suits sites standardised on 2LC SM P cabling.

Where It Is Used

Fifty-metre singlemode runs appear between buildings on a shared campus, across large exhibition and convention floors, through hospital service corridors, and along broadcast and arena cable routes where a single unbroken assembly beats a spliced field build.
