LC to ST fiber optic single-mode patch cord

An LC to ST single-mode fiber optic patch cord is a high-performance cable designed for long-distance optical communication, featuring LC and ST connectors, low attenuation, and compliance with industry standards.

Overview

An LC to ST single-mode patch cord is a fiber optic cable with an LC connector on one end and an ST connector on the other, designed for single-mode applications that require long-distance data transmission. Single-mode fiber typically has a 9/125 µm core/cladding diameter, allowing only one light propagation mode, which minimizes signal loss and supports high-bandwidth communication over long distances .

Key Specifications

• Fiber Type: Single-mode (OS1 or OS2), optimized for long-distance transmission .
• Connector Types: LC (Lucent Connector) and ST (Straight Tip) with UPC (Ultra Physical Contact) polish for low back reflection and improved signal quality .
• Attenuation: Low signal loss, typically around 0.25 dB/km at 1550 nm and 0.35 dB/km at 1310 nm, suitable for GPON, FTTX, and enterprise networks .
• Cable Jacket: Options include PVC, riser-rated, or plenum-rated, with flexibility for indoor and outdoor installations .
• Operating Temperature: Typically from -20°C to 70°C, with a minimum bending radius of 5 cm during installation .
• Length Options: Common lengths include 1m, 2m, 3m, 5m, 10m, and custom lengths are often available .

Applications

LC to ST single-mode patch cords are widely used in:

• Data centers and LANs for connecting switches, routers, and transceivers .
• Telecom networks including GPON and FTTX deployments .
• SAN (Storage Area Networks) and high-speed Ethernet networks up to 10Gbps .
• FTTH (Fiber to the Home) and enterprise optical networks .

Advantages

• Long-distance transmission: Single-mode fiber supports distances up to 10 km or more at 1310 nm .
• Low signal attenuation: Ensures stable video, data, and voice transmission .
• Standards compliance: Meets ITU-T G.652A/B, IEC 60793-2-50 Type B1.1, and RoHS environmental standards .
• Durable and flexible: Suitable for compact installations without compromising performance .

Summary

The LC to ST single-mode fiber optic patch cord is a reliable solution for high-speed, long-distance optical networks. Its combination of low attenuation, standardized connectors, and flexible installation options makes it ideal for telecom, enterprise, and data center applications, ensuring efficient and stable optical communication .
