Belden Inc. FCSD06LDFS Fiber Optic Splice Cassette OS2

Product Description

The BELDEN INC. FCSD06LDFS is a fiber optic splice cassette designed for OS2 single-mode fiber infrastructure. It provides a structured, enclosed housing for fusion or mechanical splices, keeping splice points protected and organized within a fiber distribution chassis or enclosure. The cassette format supports clean, modular fiber management in both new installations and retrofit applications. It ships as a single unit and is typically installed by low-voltage technicians, structured cabling contractors, or telecom installers working in data center, commercial building, or campus environments.

This cassette is suited for OS2 single-mode deployments where long-distance, low-loss fiber runs require reliable splice protection and tray organization. The 6-port configuration makes it appropriate for smaller distribution points or add-on capacity within an existing fiber chassis. It fits into standard fiber distribution hardware enclosures and is commonly used in backbone cabling, inter-building runs, and equipment room patching infrastructure.

Key Features

• OS2 single-mode fiber compatibility for long-distance, low-attenuation applications
• 6-port splice capacity in a compact cassette form factor
• Cassette design enables modular installation and replacement within compatible fiber chassis
• Enclosed housing protects splice points from physical damage and contamination
• Sold as a single unit (EA) for flexible quantity ordering

Compatibility

Designed as an OEM-style replacement or expansion component for compatible fiber optic distribution chassis and enclosures that accept DCX-style splice cassettes in OS2 single-mode configurations.

Installation Notes

Installation should be performed by a qualified low-voltage or fiber optic technician following applicable structured cabling standards such as ANSI/TIA-568. Before servicing any fiber enclosure, ensure all active optical equipment connected to the affected fibers is powered down and laser sources are disabled. Handle fiber ends and splice points with care to avoid contamination; use appropriate fiber cleaning tools before mating any connectors. Do not exceed the minimum bend radius of the fiber when routing inside the cassette or enclosure.
