Belden Inc. FCSH06LAFM Fiber Optic Cassette OS2 6-port

Product Description

The BELDEN INC. FCSH06LAFM is a fiber optic cassette designed for ultra-high-density structured cabling installations. Built around OS2 single-mode fiber, this 6-port cassette provides a clean, pre-terminated breakout point between backbone trunk cables and active equipment or horizontal runs. It is intended for installation in compatible high-density cassette enclosures or patch panels where organized, low-profile fiber management is required. Licensed fiber optic technicians and low-voltage structured cabling contractors are the primary installers. The cassette format reduces field splicing, speeds up moves, adds, and changes, and supports consistent insertion loss across the link.

This cassette is suited for enterprise, data center, and commercial building backbone infrastructure where OS2 single-mode fiber is the medium of choice. The 6-port configuration fits applications where circuit density per rack unit must be balanced with accessible cable management. It is typically installed in telecommunications rooms, main distribution areas, and horizontal distribution areas as part of a modular fiber enclosure system. The unit ships as a single assembly ready for insertion into a compatible cassette housing.

Key Features

• OS2 single-mode fiber platform for long-distance, low-attenuation backbone runs
• 6-port cassette format enables modular, scalable fiber distribution
• Ultra-high-density cassette form factor supports high port counts per rack unit
• Pre-terminated assembly reduces installation time and minimizes field-termination errors
• Sold as a single unit for flexible quantity purchasing

Compatibility

Designed as an OEM-style replacement or addition for ultra-high-density fiber optic cassette enclosure systems that accept OS2 single-mode 6-port cassette modules.

Installation Notes

Installation should be performed by a qualified low-voltage or fiber optic cabling technician following applicable TIA-568 structured cabling standards. De-energize or power down any active equipment connected to the fiber path before inserting or removing cassettes to protect optical transceivers. Avoid bending fiber beyond the minimum bend radius specified for OS2 cable when routing trunk and pigtail fibers inside the enclosure. Inspect ferrule end-faces with an appropriate fiber inspection scope before mating connectors to confirm contamination-free connections.
