Single-mode dual-core fiber FC-SC

A single-mode dual-core SC to FC fiber patch cord is a high-performance optical cable designed for stable, low-loss signal transmission between SC and FC interfaces.OverviewA single-mode dual-core (duplex) fiber patch cord features two optical fibers within a single cable, allowing simultaneous bidirectional communication. One end has an SC connector (square push-pull type), and the other end has an FC connector (round screw-type ferrule), providing compatibility with a wide range of telecom, data center, and FTTH equipment . The fiber is typically G.652D single-mode, optimized for long-distance transmission with minimal attenuation .Key SpecificationsFiber Type: Single-mode (G.652D)Core Diameter: 9/125 µmCable Diameter: Commonly 2.0 mm for tight-buffered protection Connector Types: SC (push-pull) to FC (screw-threaded)Polish Options: PC, UPC, or APC depending on return loss requirementsInsertion Loss: Typically ≤0.2 dB per connectorReturn Loss: ≥50 dB for high signal integrity Jacket Material: LSZH (Low Smoke Zero Halogen) or PVC, depending on fire safety requirements Durability: High mechanical stability, rated for hundreds of mating cyclesApplicationsTelecommunication Networks: Long-haul and metro fiber linksData Centers: Interconnection between switches, routers, and optical transceiversFTTH (Fiber to the Home): Connecting optical network terminals to distribution framesTest and Measurement Equipment: High-precision optical testing setupsCATV Systems: Reliable signal transmission for cable TV networks AdvantagesLow Insertion and Return Loss: Ensures minimal signal degradationHigh Reliability: Stable performance under vibration and repeated matingDual-Fiber Design: Supports simultaneous transmit and receive channelsVersatile Compatibility: SC and FC connectors allow integration with legacy and modern equipmentDurable Construction: Tight-buffered fibers and LSZH jackets provide mechanical protection and fire safety SummaryThe single-mode dual-core SC to FC fiber patch cord is ideal for high-performance optical networks requiring long-distance, low-loss, and reliable connections. Its combination of SC and FC connectors, duplex fiber design, and robust construction makes it suitable for telecom, data center, FTTH, and CATV applications, ensuring stable optical signal transmission over extended distances .
