Overview

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.

Pros & Cons

👍 Pros

  • 20-meter length spans two-rack or inter-room runs without signal integrity penalties — OM3 fiber's 300-meter 10GbE ceiling means this cable operates with 93% headroom to spare.
  • 50/125 µm OM3 core provides the modal bandwidth required for 10GbE VCSEL transmission, supporting the 850 nm wavelength used by virtually all SFP+ SR transceivers.
  • OFNR-rated aqua jacket satisfies riser fire code compliance, eliminating the need to source a separately rated cable for vertical building installations.
  • Complete electromagnetic immunity makes this cable suitable for routing alongside high-current power lines, motor drives, and other EMI sources that would corrupt copper Ethernet signals.
  • LC/LC duplex termination is plug-compatible with the SFP+ ecosystem — no adapters, no media converters required.

👎 Cons

  • Fixed 20-meter length cannot be field-shortened or extended — if your run is 22 meters, you need a different SKU, not a field modification.
  • LC ferrules require careful handling; contamination from a single fingerprint on the end-face raises insertion loss and can degrade link reliability until professionally cleaned.
  • OM3 multimode is incompatible with single-mode OS1/OS2 infrastructure — mixing fiber grades requires media converters and increases cost significantly.
  • The aqua jacket provides no mechanical protection beyond basic abrasion resistance — this cable is not rated for outdoor, direct burial, or armored conduit applications.

Frequently Asked Questions

This OM3 50/125 µm multimode cable is rated for 10 Gigabit Ethernet at distances up to 300 meters. At 20 meters, you're operating at 6.7% of that maximum reach — attenuation and modal dispersion are non-issues at this length.
The additional 5 meters matters when connecting equipment in non-adjacent racks or routing cable through overhead trays. The 20-meter length accommodates longer cabinet-to-cabinet runs and provides enough slack to re-route without purchasing a new cable if your rack layout changes.
Yes. LC duplex is the standard connector for SFP+ short-range (SR) multimode transceivers operating at 850 nm. Any 10GbE switch or NIC with an SFP+ cage and SR optics will accept this cable directly.
OFNR (Optical Fiber Non-conductive Riser) meets UL 1666 requirements for vertical cable runs through building floors and risers. It is appropriate for in-wall and in-riser installation where local fire code requires a rated jacket — though plenum-rated (OFNP) is required in air-handling ceiling spaces.
Not with this LC/LC connector configuration. 40GBASE-SR4 and 100GBASE-SR10 require MPO/MTP multi-fiber connectors. This cable is purpose-built for 10GbE (and lower-speed) LC-connected applications.
