Hubbell HGRKTD45DN Indoor/Outdoor Tight Buffer Cable OS2 SM Riser 48 Fiber Black

Overview

The Hubbell HGRKTD45DN is a 48-fiber, OS2 single-mode, riser-rated tight buffer cable designed for robust indoor and outdoor deployments. Its construction provides a balance of durability and flexibility, making it suitable for backbone connectivity in commercial buildings, data centers, and campus environments where reliable optical signal transmission is critical. The black jacket offers UV resistance for outdoor exposure and meets riser (CMR) fire-resistance standards for use within building plenums.

Compatibility

This cable is designed for termination with standard fiber optic connectors (e.g., LC, SC, ST) and is compatible with a wide range of network equipment, including managed switches, media converters, and optical transceivers. It is suitable for use with network interface devices (NIDs) and distribution frames from various manufacturers, provided they support OS2 single-mode fiber specifications. Ensure your termination and splicing equipment is rated for 48-fiber, OS2 tight buffer cable.

Installation Notes

When installing the Hubbell HGRKTD45DN, adhere to the minimum bend radius requirements to prevent signal degradation. For loaded conditions, maintain a bend radius of at least 20 times the cable diameter. For unloaded conditions, a minimum bend radius of 10 times the cable diameter is recommended. Avoid excessive pulling tension, which can exceed 100 lbs per fiber for tight buffer construction. Proper strain relief at termination points is essential for long-term reliability.
