Monoprice 138451 Fiber Optic Cable LC/UPC-LC/UPC 3 Meter

The Monoprice 138451 is a 3-meter single-mode duplex fiber optic patch cable terminated with LC/UPC connectors on both ends and manufactured to EIA/TIA 604-2 specifications for insertion loss and return loss performance. The G657A1 fiber standard — the "bend-insensitive" designation — specifies a fiber that maintains its optical performance at tighter bend radii than standard G652D single-mode fiber, which is a meaningful engineering advantage in modern data center cable management environments where routing paths through dense trays and tight corners are the norm rather than the exception. Factory termination with zirconia ceramic ferrules and individual testing for insertion loss, return loss, and physical end-face quality removes field termination variability from the performance equation — each cable shipped has been verified to meet connector standard specifications.

This cable targets data center, enterprise networking, and structured cabling applications where 10G, 40G, or 100G connectivity is required between co-located equipment — typically within a single rack or between adjacent racks in a hot-aisle/cold-aisle layout. Single-mode fiber with LC/UPC connectors is the correct infrastructure choice for laser-based SFP+ and QSFP-family transceivers in enterprise switches, storage arrays, and optical transport equipment. The 2mm PVC jacket is appropriate for in-rack and contained pathway installations; plenum-rated environments require a CMP jacket variant. Cable printing on the jacket aids identification and documentation in populated infrastructure without requiring physical tracing — a minor but practically useful feature in busy data center environments. For buyers who require standards-compliant, tested single-mode LC fiber at a cost-effective price point, this cable covers the specification without the overhead of branded premium pricing.
