West Penn Wire WP9W241T 12-fiber Sm Ofnp Armored Cable

Product Description

The WEST PENN WIRE WP9W241T is a 12-fiber singlemode armored fiber optic cable rated for both indoor and outdoor installation. It carries an OFNP (Optical Fiber Nonconductive Plenum) rating, making it suitable for use in plenum air-handling spaces where fire and smoke propagation requirements apply. The armored construction adds mechanical protection against crush, rodent damage, and rough handling in conduit runs or direct-burial-adjacent pathways. Network installers and low-voltage cabling contractors are the primary trades working with this cable.

This cable is designed for runs that transition between indoor and outdoor environments, eliminating the need for a separate splice point at the building entry. Typical applications include campus backbone runs, data center interconnects, and commercial building riser-to-exterior pathways. The plenum rating satisfies code requirements in air-handling ceiling and wall cavity spaces, while the armor jacket addresses physical plant demands in exposed or high-traffic routing zones.

Key Features

• 12-fiber singlemode construction for high-bandwidth, long-distance optical transmission
• OFNP plenum rating meets fire and smoke requirements for air-handling spaces
• Armored jacket provides mechanical protection against crush and abrasion
• Dual-rated indoor/outdoor design eliminates mid-run transition splices
• Sold per foot (unit of measure: EA)

Compatibility

Designed as an OEM-style singlemode fiber optic cable suitable for use with standard LC, SC, and ST singlemode connectors and termination hardware in plenum-rated indoor/outdoor backbone cabling systems.

Installation Notes

Installation should be performed by a licensed low-voltage or communications cabling contractor familiar with TIA-568 and NFPA 70 (NEC) Article 770 requirements for optical fiber cable. De-energize any co-located electrical systems before working in shared pathways or conduit. Do not exceed the cable manufacturer's minimum bend radius during pulling or routing, as kinking singlemode fiber can cause permanent signal loss. Armor termination and cable end-sealing should follow standard practices to maintain the environmental rating of the cable run.
