An LC-SC single-mode fiber optic patch cord is a high-performance cable designed for long-distance optical communication, featuring LC and SC connectors on either end and 9/125 µm OS2 single-mode fiber.

Key Features

Fiber Type: LC-SC patch cords use single-mode OS2 fiber with a 9/125 µm core/cladding diameter, optimized for long-distance transmission with minimal signal loss, capable of reaching distances up to 10 km or more depending on wavelength and network conditions . Connectors:

• LC Connector: Small form-factor connector with a 1.25 mm ferrule, ideal for high-density applications.
• SC Connector: Square-shaped connector with a 2.5 mm ferrule, featuring a push-pull locking mechanism for secure connections .
• The patch cord can be LC to SC or SC to LC, supporting both simplex (single strand) and duplex (two strands for bidirectional communication) configurations . Polish Types: Available in UPC (Ultra Physical Contact) or APC (Angled Physical Contact) polish, which affects return loss and reflection performance. APC connectors are preferred for high-precision, long-distance applications due to lower back reflection . Cable Construction:
• Typically features plenum-rated or LSZH jackets for fire safety in indoor installations .
• Available in various lengths, from 0.3 meters to 300 meters, to accommodate different network layouts .
• Type A (straight-through) or Type B (crossed) polarity options are available to match network requirements . Performance:
• Low insertion loss (<0.3 dB typical) and low return loss, ensuring high signal integrity for mission-critical applications .
• Factory-tested for optical quality, guaranteeing reliable performance in data centers, telecom backbones, and enterprise networks .

Applications

• Telecommunications: Connecting central offices, long-haul fiber runs, and backbone networks.
• Data Centers: High-speed connectivity between switches, routers, and storage devices.
• Enterprise Networks: Linking optical distribution frames (ODFs), transceivers, and network equipment.
• Indoor and Outdoor Installations: Suitable for both environments depending on jacket type and protection requirements .

Summary

An LC-SC single-mode fiber optic patch cord is a versatile, high-performance cable designed for long-distance optical communication. Its combination of LC and SC connectors, single-mode OS2 fiber, low-loss construction, and customizable lengths makes it ideal for data centers, telecom networks, and enterprise applications requiring reliable, high-speed connectivity .
