Belden Inc. FM3MMB1007M OM3 Mpo 12-fiber Patch Cable

Product Description

The BELDEN INC. FM3MMB1007M is an OM3 multimode fiber optic patch cable configured with a 12-fiber MPO connector in a male-to-male (Type B) pinning arrangement. At 7 meters in length, this trunk-style cable is built for structured cabling environments where high-density fiber connectivity is required. OM3 glass supports 10 Gigabit Ethernet at distances up to 300 meters, making this cable well-suited for backbone and cross-connect runs in data centers and enterprise network closets. Installation is handled by low-voltage cabling technicians and network infrastructure professionals.

The FM3MMB1007M fits into high-density patch panel systems, MPO cassette modules, and fiber distribution units. Its Type B polarity configuration is appropriate for parallel optics applications and direct MPO-to-MPO connections where maintaining fiber lane alignment is critical. With 12 fibers terminated on a single MPO interface, it supports parallel 40G and 100G transmission when used with compatible transceivers and breakout modules. This cable is commonly deployed in data center top-of-rack and end-of-row switching architectures.

Key Features

• OM3 multimode fiber supports 10GbE backbone runs and parallel 40G or 100G optical links
• 12-fiber MPO connector provides high-density termination in a single plug
• Male-to-male (M-M) Type B polarity for direct MPO-to-MPO cross-connect applications
• 7-meter length accommodates inter-rack and intra-row cable management runs
• Factory-terminated and tested assembly reduces on-site splicing labor

Compatibility

Designed as an OEM-style patch cable for use with MPO-based fiber distribution systems, cassette modules, and patch panels that accept 12-fiber MPO male connectors in OM3 multimode infrastructure.

Installation Notes

Installation should be performed by a qualified low-voltage cabling technician familiar with fiber optic handling procedures. Always inspect and clean MPO connectors before mating to prevent insertion loss from contamination. Do not exceed the minimum bend radius of the cable during routing and dressing. Power down active transceivers or ports before connecting or disconnecting fiber patch cables to protect optical components.
