Belden Inc. FDSD012P9 Singlemode Plenum Fiber Cable

Product Description

The BELDEN INC. FDSD012P9 is a 12-fiber singlemode distribution cable rated for plenum environments. It is designed for in-out routing applications where the cable transitions between inside plant runs and interconnect points within the same pathway. The plenum rating makes it suitable for installation in air-handling spaces and return-air plenums where fire and smoke propagation requirements apply. Licensed low-voltage cabling contractors and data communications technicians typically specify and install this cable in structured cabling systems, enterprise backbone runs, and campus distribution architectures.

This cable is intended for indoor plenum installations where singlemode fiber is required to support long-distance, high-bandwidth transmission. The in-out construction allows it to serve both horizontal and vertical distribution segments. It is sold as a single unit and is appropriate for commercial and enterprise environments where building and fire codes require plenum-rated cable jacket materials in air-handling spaces.

Key Features

• 12-fiber count provides substantial capacity for backbone and distribution runs
• Singlemode fiber supports high-bandwidth, long-distance transmission
• Plenum-rated jacket meets fire and smoke requirements for air-handling spaces
• In-out construction supports flexible routing between distribution and interconnect points
• Black jacket finish for easy identification in structured cabling installations

Compatibility

Designed as an OEM-style singlemode plenum fiber distribution cable for use in standard structured cabling and fiber backbone systems requiring a 12-fiber plenum-rated in-out cable.

Installation Notes

Installation should be performed by a licensed low-voltage contractor or qualified data communications technician familiar with TIA-568 structured cabling standards and local fire codes. De-energize and isolate any active equipment before terminating fiber runs. Minimum bend radius must be observed during pulling and routing to avoid fiber damage. Plenum spaces should be confirmed to meet NEC Article 800 or applicable local code requirements before cable is routed through air-handling areas.
