Extron 2LC OM4 MM P/15 (part number 26-671-15) — 15 meters of duplex OM4 multimode fiber with LC ends and a plenum-rated jacket. Extron now lists this part number as retired.

Fifteen meters covers the awkward middle distance: too long for a patch cord, too short to justify pulling bulk fiber and field-terminating it. A factory-terminated assembly of this length lets an integrator drop a finished, tested optical link between two rooms or between a floor closet and an AV rack without buying a fusion splicer. The glass is laser-optimized OM4 and bend-insensitive, so the inevitable turns at each end cost very little optical budget.

Key Capabilities

• 15 m (49.2 ft) factory-terminated length — no field polishing required.
• Two-fiber OM4 duplex construction with aramid yarn reinforcement.
• Attenuation under 3.0 dB per km at 850 nm and under 1.2 dB per km at 1300 nm.
• Insertion loss under 0.5 dB per 300 m at either operating wavelength.
• ETL/c-ETL OFNP FT6 plenum listing for concealed ceiling routing.
• Retired Extron part number — availability is limited to remaining stock.

Where It Is Used

This length suits inter-room Extron fiber links in medical imaging departments, courtrooms, training centers and control rooms, plus replacement of an existing 15 meter optical run where matching the original assembly length avoids re-dressing the pathway.
