Extron 2LC SM P/5 (part number 26-670-05) — a 5 metre (16.4 ft) duplex LC singlemode fiber cable built for plenum-rated runs between rooms and racks.

At five metres the cable stops being a jumper and starts being an interconnect. It is long enough to cross a rack row, drop from a ceiling-mounted transmitter to a wall box, or reach a projector on the far side of a lectern. What does not change with length is the optical behaviour: two singlemode glass fibers, LC ends with a UPC polish, and attenuation Extron specifies at less than 0.5 dB over a full kilometre. Bend-insensitive fiber means the slack you inevitably coil at one end costs nothing measurable.

Key Capabilities

• 5 m (16.4 ft) reach in a duplex zip-cord assembly measuring 2.0 mm x 4.0 mm.
• Singlemode 8.3 µm glass fiber supporting Extron AV transport as far as 30 km (18.75 miles).
• Both ends terminated with industry-standard LC connectors, UPC polished.
• Plenum rated — ETL and c-ETL listed to OFNP FT6.
• Post-installation fiber bend radius as tight as 0.3 in (7.5 mm).
• PVC jacket with aramid yarn strengthening throughout.

Where It Is Used

Five-metre singlemode assemblies serve divisible meeting rooms, teaching walls, hospital procedure rooms, transit and utility control desks, and equipment rooms where the transport endpoint and the fiber patch field sit in different cabinets. The plenum rating keeps the same part usable above ceilings and under raised floors.
