The Opti-Core Pull-Boot LC Duplex Fiber Optic Patch Cords shall provide high performance essential for today’s high-speed systems with a connector that allows easy polarity change in the field without any mechanical components that can be unfastened or misplaced. In addition, the 2.0mm, 2-fiber round unitary cable construction reduces cable volume by 50 percent making the patch cords ideal for reducing cable congestion in extremely high density patch fields. These patch cords are available in plenum (OFNP) or low smoke zero halogen (LSZH) rated jacket materials along with OM4, OM4+, OM5, and OS2 fiber types. The connectors are available in UPC (multimode and singlemode) and APC (singlemode only) end faces.
