Fiber optic cable FC-LC single-mode

A single-mode FC-LC fiber optic cable is a high-performance patch cord designed for long-distance, low-loss optical transmission, featuring a threaded FC connector and a compact LC connector.

Overview

Single-mode FC-LC fiber optic cables use a 9/125 µm core/cladding diameter (OS2 standard) to transmit light over long distances with minimal signal loss. The FC connector (Ferrule Connector) has a threaded body, making it highly reliable in high-vibration environments, while the LC connector (Lucent Connector) is a small form-factor (SFF) connector ideal for high-density applications in data centers and SFP/SFP+ modules .

Key Features

• Fiber Type: Single-mode (SMF-28e or OS2), 9/125 µm
• Connector Types: FC (screw-threaded) to LC (small form-factor)
• Jacket: Typically yellow PVC or optional LSZH, plenum, or riser-rated
• Cable Diameter: Commonly 2.0–3.0 mm
• Insertion Loss: ≤ 0.2 dB for high-quality cables
• Return Loss: ≥ 45–60 dB, ensuring minimal back reflection
• Durability: Ceramic ferrules, pull-proof design, resistant to bending and pulling
• Operating Temperature: -20°C to +60°C (storage up to -40°C to +80°C)

Applications

• Telecommunications: Long-haul networks, ODF frames, and telecom base stations
• Data Centers: High-density patch panels and SFP/SFP+ modules
• Professional Networking: Transceiver equipment, communication rooms, and high-bandwidth links
• Industrial Environments: Environments with vibration or mechanical stress due to FC threaded connector

Advantages

• Low Signal Loss: Single-mode fiber ensures minimal attenuation over long distances
• High Return Loss: Reduces reflection and improves signal integrity
• Compact and High-Density: LC connector allows for more ports in limited space
• Durable and Reliable: FC connector provides secure, vibration-resistant connections
• Versatile: Compatible with standard LC and FC interfaces, suitable for both simplex and duplex configurations

Purchasing Options

FC-LC single-mode cables are available in various lengths (1 m to 15 m or custom), simplex or duplex, and with different jacket types for indoor, outdoor, or plenum-rated installations. Many suppliers offer pre-tested insertion loss and return loss to ensure performance . In summary, an FC-LC single-mode fiber optic cable is ideal for high-performance, long-distance optical networks requiring secure, low-loss connections with a combination of rugged FC and compact LC connectors.
