Extron 2LC OM4 MM P/50 (part number 26-671-50) — a 50 meter duplex OM4 multimode assembly with LC terminations and a plenum-listed jacket. This part number is retired by Extron.

Fifty meters puts the link firmly into inter-floor and inter-zone territory. One pull covers a riser between floors, a long service corridor, or the distance from a head-end room to a remote equipment position at the far side of a venue. Nothing about the optical construction changes with length — the same laser-optimized OM4 glass, the same UPC-polished LC ends — but the pre-terminated format saves an hour or more of on-site work per link.

Key Capabilities

• 50 m (164 ft) pre-terminated duplex OM4 fiber assembly.
• Two glass fibers over an aramid yarn strength member in a PVC jacket.
• Rated for continuous operation from 0 to +70 °C.
• Attenuation under 3.0 dB per km at 850 nm and under 1.2 dB per km at 1300 nm.
• ETL/c-ETL OFNP FT6 plenum listing for riser and ceiling pathways.
• Retired Extron part number — remaining supply only.

Where It Is Used

Fifty-meter Extron optical links run between floors in hospitals, across arena and convention concourses, along university corridors and through broadcast facility risers — spans where copper AV cabling is no longer viable but the distance sits well within multimode reach.
