Hubbell HGRKTD90DN Indoor Interlock Armored Tight Buffer Fiber Cable OS2 SM Plenum 12 Fiber Yellow

Overview

The Hubbell HGRKTD90DN is a 12-fiber, OS2 single-mode, plenum-rated, interlock armored tight buffer fiber optic cable. Its construction provides enhanced crush resistance and protection for indoor network backbone and horizontal cabling runs where plenum fire ratings are mandatory. This cable is designed for environments requiring robust physical protection without compromising signal integrity, making it suitable for data centers, commercial buildings, and educational facilities. The HGRKTD90DN model features a yellow jacket for easy identification.

Compatibility

This cable is designed for termination with standard fiber optic connectors (e.g., LC, SC, ST) and is compatible with all standard fiber optic termination tools and equipment. It is suitable for use with various fiber optic splice closures, patch panels, and media converters commonly found in enterprise and data center networks. Its OS2 single-mode specification ensures compatibility with high-bandwidth, long-distance transmission systems.

Installation Notes

The interlock armor provides significant crush resistance, but care should still be taken to avoid sharp bends exceeding the minimum bend radius of 20mm (tight bend) or 10mm (slack bend) to prevent signal loss or cable damage. The plenum rating requires installation in air-handling spaces, adhering to local building codes and fire safety regulations. Termination requires standard fiber optic cleaving, stripping, and splicing or connectorization tools.
