Extron 2LC OM4 MM P/60 (part number 26-671-60) — at 60 meters, the longest factory-terminated assembly in the Extron 2LC OM4 MM P family. Now a retired part number.

This is the maximum stock length in the series, and it exists for the runs that would otherwise force an integrator into bulk fiber and field termination. Sixty meters covers a full building wing, a stadium bowl segment, or a multi-floor riser, delivered as one continuous piece of laser-optimized OM4 glass with factory-polished LC ends at each side. Bend-insensitive fiber matters more at this length, since a long path accumulates more turns.

Key Capabilities

• 60 m (197 ft) — the longest assembly in the 2LC OM4 MM P range.
• One continuous duplex fiber path with factory-polished LC ends.
• Bend-insensitive glass holds a 0.3 in (7.5 mm) radius after installation.
• Under 3.0 dB per km at 850 nm; under 1.2 dB per km at 1300 nm.
• ETL/c-ETL OFNP FT6 plenum rating for concealed building pathways.
• Retired Extron part number.

Where It Is Used

Sixty-meter optical links connect Extron fiber transmitters and receivers across stadium bowls, hospital wings, convention halls and multi-floor corporate risers, replacing long copper AV runs that would otherwise need repeaters or intermediate equipment positions.
