Extron 2LC SM P/20 (part number 26-670-20) — 20 metres (65.6 ft) of LC-to-LC singlemode fiber, factory terminated and rated for plenum installation.

Twenty metres is a building-scale link. It gets fiber from a head-end rack to a distant equipment position without a splice tray, an enclosure or a technician with a fusion splicer on site. The optical package is unchanged from the shorter members of the 2LC SM P range — two singlemode glass fibers, UPC-polished LC ferrules, attenuation below 0.5 dB per kilometre — but at this length the bend-insensitive construction earns its keep, because a 20 m route will always include a corner someone routed too tightly.

Key Capabilities

• 20 m (65.6 ft) continuous duplex singlemode assembly, no field termination needed.
• Fiber bend radius as tight as 0.3 in (7.5 mm) once the run is installed.
• Two glass fibers behind a PVC jacket listed ETL/c-ETL OFNP FT6.
• Insertion loss specified below 0.3 dB per 300 m at 1550 nm.
• LC connectors sized 48.5 mm x 4.47 mm x 4.47 mm for standard fiber panels.
• Extron Limited Lifetime Performance warranty coverage.

Where It Is Used

Runs of this length link auditorium projection booths to stage racks, MRI and CT suites to their technical rooms, arena camera positions to production control, and data-adjacent AV closets to distribution frames — anywhere the two ends of the link are in different rooms but the same building.
