An LC to FC fiber optic patch cord is a singlemode or multimode cable with LC connector on one end and FC connector on the other, designed for reliable optical signal transmission between modern and legacy equipment.

Overview

An LC to FC fiber patch cord is a pre-terminated fiber cable that connects devices with different connector types, such as LC-equipped SFP transceivers to FC-equipped legacy network hardware or test equipment . It is commonly used in telecommunication networks, data centers, and enterprise server interconnections .

Key Specifications

• Fiber Type: Typically singlemode OS2 (9/125µm) for long-distance transmission, optimized for 1310nm and 1550nm wavelengths . Multimode options are also available for shorter distances .
• Connector Types: LC connector (small form-factor, clip-style) on one end and FC connector (threaded, robust) on the other .
• Polish Type: UPC (Ultra Physical Contact) polish ensures low insertion loss (≤0.3dB) and high return loss (≥50dB) for stable signal quality .
• Cable Jacket: Options include LSZH (Low Smoke Zero Halogen) for indoor safety, PVC, or OFNP/OFNR for fire-rated installations .
• Cable Diameter: Commonly 2.0mm or 3.0mm, with lengths customizable from 1m to 10m or more .
• Performance Testing: Each cord is factory-tested for insertion loss and return loss, often meeting Telcordia GR-326-CORE standards .

Applications

• Connecting modern SFP transceivers to legacy FC devices
• Telecommunication networks including metro, access, and long-haul systems
• Data centers and enterprise networks for server interconnections
• Optical test equipment and laboratory setups

Advantages

• Low signal attenuation and high transmission stability
• Durable and flexible jacket suitable for indoor installations, walls, ceilings, and conduits
• High compatibility with standard fiber optic equipment
• Plug-and-play installation with minimal setup

Selection Tips

• Choose singlemode for long-distance or high-speed networks, multimode for short-distance applications .
• Select LSZH jackets for indoor safety or PVC/OFNP for general use .
• Ensure the connector polish type matches your equipment (UPC vs APC) to minimize reflection and signal loss .
• Verify cable length and flexibility requirements based on installation environment . LC to FC patch cords provide a reliable bridge between modern and legacy optical systems, ensuring low-loss, high-quality signal transmission in diverse network environments .
