Fiber optic patch cord dual-fiber LC interface

A dual-core LC fiber optic patch cord is a duplex cable with two fibers terminated with LC connectors, available in single-mode or multimode, designed for high-density and reliable network connections.

Overview

A dual-core LC patch cord consists of two optical fibers within a single cable, each terminated with an LC connector. These cords are commonly used in data centers, telecommunications, and FTTX networks to provide high-speed, low-loss connections between devices, patch panels, and network equipment. Types and FeaturesSingle-mode (SM) vs Multimode (MM): Single-mode fibers (e.g., OS2, G.

657. A2) are used for long-distance transmission, while multimode fibers (e.g., OM4) are suitable for shorter distances with higher bandwidth. Duplex vs Uniboot: Standard duplex cables have two separate fibers, whereas uniboot LC patch cords integrate both fibers into a single compact jacket, saving space and improving airflow in high-density racks.

Bend-insensitive fibers: Many dual-core LC cords use bend-insensitive fibers, allowing a minimum bending radius as small as 10mm, reducing signal loss in tight spaces. Jacket types: Options include LSZH (Low Smoke Zero Halogen) for indoor use and outdoor-rated jackets for harsh environments. Polarity and connector standards: LC connectors comply with IEC 61754-20, and polarity can be interchangeable in uniboot designs, simplifying installation.

Applications

Data centers: High-density patching and space-saving cable management. Telecommunications: FTTX and outside plant connections. Enterprise networks: Reliable voice, data, and video transmission.

Indoor/outdoor environments: Outdoor-rated cords withstand harsh conditions, while LSZH jackets are ideal for office or telecom rooms.
