Fiber Optic Cable StarTech.com SMFIBLCSC4 4m Single-Mode Duplex 9/125

The StarTech.com SMFIBLCSC4 4m Single-Mode Duplex 9/125 fiber optic cable provides LC to SC connectivity for high-speed, high-bandwidth data transmission over Gigabit Ethernet and Fiber Channel networks. This single-mode OS1 duplex cable has a 9/125 µm core/cladding construction and supports full-duplex single-mode applications. The cable jacket is LSZH (Low-Smoke, Zero-Halogen), reducing smoke and toxic emissions in the event of fire and making it suitable for environments with strict safety or building-code requirements.

Advantages

This LC to SC single-mode duplex cable is individually tested and certified for acceptable optical insertion loss limits to ensure compatibility and reliable performance. The LSZH flame-retardant jacket minimizes smoke and corrosive gases, making the cable appropriate for industrial sites, central offices, schools, and residential buildings where low-halogen materials are required. The product is covered by StarTech.com’s lifetime warranty.

How to use

Identify the LC and SC ends of the duplex cable and align connectors with the corresponding ports on network devices or patch panels. Gently insert each connector until it clicks or seats fully; avoid bending the fiber beyond its minimum bend radius. For duplex links, ensure transmit and receive pairs are correctly paired between devices. Secure cables in routing trays or ties designed for fiber to prevent strain and maintain optimal optical performance.

Usage recommendations

For best results, perform end-to-end optical testing after installation to verify insertion loss and continuity. Avoid tight bends and excessive pulling force during installation. Use LC dust caps when connectors are not in use to protect endfaces from contamination.
