Extron 2LC OM4 MM P/3 (part number 26-671-03) — a 3 meter duplex LC fiber assembly on laser-optimized OM4 multimode glass with an OFNP plenum jacket.

Three meters is the length most integrators reach for when the fiber endpoint and the patch field share a rack but not a panel: long enough to route down a vertical manager and back up, short enough to avoid coiling waste. Each end carries an LC connector with a UPC polish, and the 48.5 mm connector body fits the tight LC spacing used on high-density cassettes. Bend-insensitive fiber keeps loss stable through the turns that vertical routing demands.

Key Capabilities

• 3 m (9.8 ft) length suits same-rack, different-panel fiber routing.
• Laser-optimized OM4 glass at 50 µm core and 125 µm cladding.
• Connector bodies measure 1.91 in x 0.18 in x 0.18 in for dense LC fields.
• Attenuation held under 3.0 dB/km at 850 nm and 1.2 dB/km at 1300 nm.
• Aramid yarn strength member protects the fiber during pulls and dressing.
• Plenum-rated ETL/c-ETL OFNP FT6 jacket for return-air ceilings.

Where It Is Used

This length shows up in broadcast master control, medical video distribution racks, esports production carts and simulation labs — installations where Extron optical endpoints must reach a fiber cassette a panel or two away and code requires plenum-rated jacketing.
