Extron 2LC OM4 MM P/1 (part number 26-671-01) — a 1 meter duplex LC-to-LC multimode fiber optic patch cable built on laser-optimized OM4 glass and jacketed for plenum installation.

This is the shortest assembly in Extron's 2LC OM4 MM P family, sized for rack-internal patching where a fiber transmitter, receiver or matrix frame sits within arm's reach of the optical patch panel. Two glass fibers ride in a duplex zip-cord jacket over an aramid yarn strength member, and both ends terminate in industry-standard LC connectors finished with a UPC polish. Because the fiber is bend-insensitive, the assembly tolerates the tight turns a short rack run forces on it without the loss penalty ordinary multimode would incur.

Key Capabilities

• 1 m (3.3 ft) finished length — a true rack jumper rather than a cut-down long run.
• 50 µm (OM4) / 125 µm laser-optimized multimode glass for high-resolution Extron fiber links.
• Attenuation stays under 3.0 dB per km at 850 nm and under 1.2 dB per km at 1300 nm.
• Insertion loss is held below 0.5 dB per 300 m at either 850 nm or 1300 nm.
• ETL/c-ETL OFNP FT6 listing clears the cable for plenum air-handling spaces.
• Post-installation fiber bend radius of just 0.3 in (7.5 mm).

Where It Is Used

Short OM4 jumpers like this one live inside equipment racks in broadcast facilities, hospital imaging suites, university lecture halls and command centers — anywhere an Extron fiber endpoint has to reach a nearby LC patch field, cassette or fiber switch without slack cable piling up behind the rails.
