Monoprice 141218 Fiber Optic Cable 7 Meter LC/LC OM3

The Monoprice 141218 is a 7-meter OM3 duplex LC/LC multimode fiber patch cable built on Corning 50/125 glass. OM3 fiber's significance is its Effective Modal Bandwidth rating — at ≥2000 MHz·km, it provides the modal bandwidth headroom required for 10GbE (10GBASE-SR) over 850nm VCSEL transceivers across distances up to 300 meters. At 7 meters, the cable operates so far within its distance and bandwidth envelope that optical loss is effectively irrelevant — the link's stability is governed entirely by transceiver quality, not the fiber. The aqua jacket adheres to TIA-598 color coding for OM3, which matters in production environments where quick visual identification of fiber type prevents costly mispatching with single-mode runs.

This cable fits squarely in the intra-rack and cross-rack 10GbE interconnect role — server to TOR (top-of-rack) switch, switch uplink to core, or storage array to fabric switch. It is the appropriate choice anywhere you're deploying 10GbE SFP+ ports that require short-range fiber rather than DAC (Direct Attach Copper) twinax, typically when distance exceeds the 5–7 meter practical limit of passive DAC cables or when EMI isolation in a dense switching environment is a priority. The Corning fiber origin provides documented conformance to the OM3 specification, which matters for environments where link SLAs require verifiable component quality at the glass level rather than relying on brand-name commodity fiber whose glass origin is unspecified.
