Belden Inc. FDSD144LKY OS2 144 Fiber Distribution Cable

Product Description

The BELDEN INC. FDSD144LKY is a fiber optic distribution cable designed for structured cabling installations in commercial and industrial environments. Based on the part number designation, this cable is an OS2 single-mode fiber assembly with a 144-fiber count, suitable for high-density backbone and riser runs. OS2 single-mode fiber supports long-distance, high-bandwidth signal transmission with low attenuation, making it a standard choice for data centers, campus networks, and inter-building runs. Licensed low-voltage and structured cabling technicians are the typical installers for this product.

This cable is used in commercial and enterprise network infrastructure where high fiber counts are required in a compact, manageable format. Distribution-style construction provides individual fiber subunits that allow field termination without breakout hardware, supporting efficient deployment in telecommunications rooms, main distribution frames, and horizontal or vertical backbone pathways. The OS2 rating makes it appropriate for runs requiring single-mode performance over extended distances.

Key Features

• OS2 single-mode fiber classification for long-distance, low-attenuation signal transmission
• 144-fiber count supports high-density cabling infrastructure
• Distribution cable construction allows direct field termination of individual fiber subunits
• Suitable for backbone, riser, and inter-building structured cabling applications
• Sold as a single unit (EA) per order

Compatibility

Designed as an OS2 single-mode fiber distribution cable for use in commercial structured cabling systems. No specific compatible hardware, panels, or system families were identified in the available product data.

Installation Notes

Installation should be performed by a qualified low-voltage or structured cabling technician familiar with TIA-568 and applicable local codes. De-energize and verify all active equipment connected to the fiber pathway before splicing or terminating. Observe minimum bend radius requirements throughout the pull and termination process to prevent fiber damage. Proper cable management hardware should be used to support the cable along its entire run.
