Extron 2LC SM P/60 (part number 26-670-60) — at 60 metres (197 ft) this is the longest assembly Extron ever built in the 2LC SM P singlemode range. The part is retired; Ampronix lists it for sites extending or repairing an installed run.

Everything that makes the shorter 2LC SM P cables useful scales up here. Two singlemode glass fibers, 8.3 µm, carry the link; aramid yarn absorbs pulling force over the full 197 feet; the PVC jacket holds an ETL and c-ETL OFNP FT6 listing so the cable is legal in plenum airspace end to end. Terminating 60 metres in the field would mean four connector polishes and a test set — the factory assembly removes that step entirely.

Key Capabilities

• 60 m (197 ft) — the maximum length in Extron's 2LC SM P singlemode family.
• Delivered pre-terminated with LC/UPC connectors, no on-site polishing.
• Duplex construction: 2 glass singlemode fibers in one 2.0 mm x 4.0 mm jacket.
• Attenuation specified below 0.5 dB per km at both 1310 nm and 1550 nm.
• ETL and c-ETL OFNP FT6 plenum listing across the entire run.
• Works from 0 to +70 °C, covering ceiling voids and unconditioned risers.

Where It Is Used

Sixty-metre singlemode assemblies handle inter-building campus hops, full-floor distribution in convention and exhibition venues, large medical facility backbones, and stadium or transport-hub AV routes where the transmitter and receiver are separated by structure rather than by room.
