Belden FPS4F4F003M OS2 MPO8 Fiber Patch Cable 3M

Product Description

The Belden FPS4F4F003M is an OS2 single-mode fiber optic patch cable terminated with MPO8 female connectors on both ends. This trunk-style cable is designed for high-density fiber interconnect applications where low insertion loss and precise alignment are required. At 3 meters in length, it suits short-run backbone links between patch panels, switches, and active equipment in structured cabling environments. Licensed network technicians and low-voltage cabling contractors are the primary installers. The OS2 designation indicates a tight-buffered or loose-tube single-mode construction rated for longer reach and lower attenuation than multimode alternatives.

This cable is suited for data centers, enterprise network closets, and telecom rooms where high-density MPO connectivity is standard. The MPO8 female-to-female configuration supports 40G and 100G parallel-optic applications when paired with compatible transceivers and breakout assemblies. The 3-meter reach makes it appropriate for intra-rack and adjacent-rack patching scenarios without excess slack management concerns.

Key Features

• OS2 single-mode fiber construction for low attenuation over longer distances
• MPO8 female connectors on both ends for high-density panel-to-panel or device-to-device patching
• 3-meter length designed for intra-rack and short inter-rack runs
• Compatible with 40G and 100G parallel-optic transceiver architectures
• Factory-terminated and factory-tested for consistent insertion loss performance

Compatibility

Designed as an OEM-style replacement or add-on patch cable for high-density OS2 single-mode MPO8 fiber infrastructure installations.

Installation Notes

Installation should be performed by a licensed low-voltage cabling technician or qualified network infrastructure professional. Before connecting or disconnecting MPO connectors, ensure transceivers and active equipment ports are powered down or laser-disabled to prevent eye hazard from exposed fiber optic output. Handle MPO ferrules with care and use appropriate dust caps when ports are not in use, as contamination is the leading cause of elevated insertion loss. Follow TIA-568 and applicable local structured cabling standards during installation.
