Description

StarTech DMFKSLCLCCOUPLER LC Fiber Coupler

Overview

This StarTech DMFKSLCLCCOUPLER is a passive fiber optic coupler designed to join two LC duplex fiber optic cables. It's essential for extending existing fiber runs or connecting two separate fiber optic networks without requiring active electronics. The straight-through, passive design ensures minimal signal degradation, making it suitable for high-speed data transmission in surveillance, networking, and telecommunications deployments.

Compatibility

The DMFKSLCLCCOUPLER is compatible with both single-mode and multi-mode fiber optic cables terminated with LC duplex connectors. It supports data rates up to 100Gbps, making it suitable for high-bandwidth applications including 10GbE, 40GbE, and 100GbE networks. Use this coupler to extend fiber optic backbone connections for IP cameras, NVRs, or network switches where existing cable lengths are insufficient.

Installation Notes

The coupler features a compact form factor (1.1 in. x 0.7 in. x 0.9 in.) and a simple push-in connection. Ensure both connected LC duplex connectors are clean and free from debris before insertion to maintain optimal performance and achieve the specified <0.2dB insertion loss. The operating temperature range is -20 to 60°C (-4 to 140°F), suitable for most indoor installation environments.
