Monoprice 107623 20M Fiber Optic Cable LC/LC Multi-Mode

The Monoprice 107623 is a 20-meter OM3 multimode duplex fiber patch cable with LC/LC connectors, rated for 10 Gigabit Ethernet. The OM3 fiber grade specifies a minimum modal bandwidth of 2000 MHz·km at 850 nm — the VCSEL wavelength used by SFP+ SR transceivers — which means the fiber's light-carrying capacity is engineered specifically for laser-based 10GbE transmission, not legacy LED-driven 1GbE. At 20 meters, the cable operates well within the physics of OM3: insertion loss at this distance is typically under 1 dB including connector losses, leaving substantial link budget margin for real-world connector contamination and aging. The OFNR jacket is UL 1666-listed, authorizing use in building risers where fire code requires rated cabling.

The 107623 targets network installers and IT administrators building 10GbE switched infrastructure in environments where copper is impractical — server rooms with high electromagnetic noise, runs adjacent to power distribution equipment, or any installation where ground loops on copper Ethernet would be a concern. The 20-meter length is the practical step up from 15-meter patch cables, covering two-rack spans, MDF-to-IDF connections within a single floor, or any run where cable tray routing adds distance beyond a direct line-of-sight measurement. There is no configuration, no drivers, and no active components — performance is entirely determined by the fiber grade and connector quality, both of which Monoprice sources to OM3 specification.
