Belden Inc. FISM012P0 OS2 12-fiber Indoor Mini Distribution Cable

Product Description

The BELDEN INC. FISM012P0 is an OS2 single-mode indoor mini distribution fiber optic cable with a 12-fiber count and an OFNP (Optical Fiber Nonconductive Plenum) rating. Built for low-smoke, flame-retardant plenum air-handling spaces, this cable meets the fire safety requirements for installation in ceilings, raised floors, and HVAC return-air plenums. The mini distribution construction keeps the overall diameter compact while housing 12 individual fibers, making it well suited for high-density backbone and horizontal runs inside commercial and institutional buildings. Licensed low-voltage and datacom contractors are the typical installing trade.

This cable is used in indoor enterprise, commercial, and institutional fiber optic distribution systems where a plenum-rated, single-mode OS2 cable is required. Typical applications include backbone risers, horizontal runs between telecom rooms and work areas, and patch connections in data centers or structured cabling systems. The OS2 single-mode specification supports long-distance, high-bandwidth transmission over the 12 fibers within a single compact jacket.

Key Features

• OS2 single-mode fiber for long-distance, high-bandwidth indoor applications
• 12-fiber count in a compact mini distribution form factor
• OFNP plenum rating meets fire safety codes for air-handling space installations
• Low-smoke, flame-retardant jacket suitable for ceilings, raised floors, and HVAC plenums
• Mini distribution design supports high-density cable routing and termination

Compatibility

Designed as an OEM-style indoor mini distribution cable compatible with standard OS2 single-mode fiber optic connectors and termination hardware used in commercial structured cabling systems.

Installation Notes

Installation should be performed by a licensed low-voltage or datacom contractor familiar with TIA-568 structured cabling standards and local fire codes governing plenum-rated cable use. De-energize and verify all connected equipment is powered down before terminating or splicing fiber runs. Avoid exceeding the cable minimum bend radius during pulling and routing, as exceeding it can cause signal loss or fiber damage. Confirm the plenum rating is required and permitted by the authority having jurisdiction before installation in air-handling spaces.
