Extron 2LC SM P/15 (part number 26-670-15) — a 15 metre (49.2 ft) duplex LC singlemode fiber assembly for plenum runs that cross a floor rather than a rack.

Once a fiber link passes about ten metres, the practical questions become jacket rating and pull strength rather than optical loss. This assembly answers both: aramid yarn takes the strain during the pull, and the PVC jacket carries an ETL and c-ETL OFNP FT6 listing so the cable can legally occupy plenum airspace. Inside, two singlemode glass fibers with LC/UPC ends deliver the same low-loss transmission Extron specifies across the whole 2LC SM P family, unchanged by the extra length.

Key Capabilities

• 15 m (49.2 ft) of pre-terminated duplex singlemode fiber in one jacket.
• Aramid yarn strength members carry pulling load away from the glass.
• OFNP FT6 plenum listing from ETL and c-ETL for above-ceiling routing.
• Attenuation held under 0.5 dB per km at 1310 nm and at 1550 nm alike.
• Bend-insensitive fiber tolerating 0.3 in (7.5 mm) once the run is dressed in.
• Compact 2.0 mm x 4.0 mm duplex profile eases congested conduit fills.

Where It Is Used

Fifteen-metre singlemode runs connect floor boxes to equipment closets, stage positions to control rooms, surgical suites to the adjacent technical space, and sports venue camera plates to production areas — distances beyond copper comfort but still well inside one building.
