Lc Single-mode Dual-core Fiber Optic
LC single-mode dual-core fiber optic cables are high-performance OS2 9/125 duplex cables designed for long-distance, high-speed data transmission with LC connectors.
Overview
LC single-mode duplex fiber optic cables feature two cores (dual-core), allowing simultaneous bidirectional data transmission. They are typically OS2 single-mode fibers with a 9-micron core and 125-micron cladding, optimized for long-distance communication with minimal signal loss . The cables are commonly used in 1G, 10G, 40G, 100G, and 400G Ethernet networks, supporting distances up to 10 km at 1310 nm and 40 km at 1550 nm .
Connector Type
These cables use LC (Lucent Connector) connectors, which are 1.25 mm ferrule small form factor connectors. LC connectors are compact, allowing high-density port deployment in data centers and telecom racks. They provide low insertion loss, minimal signal interference, and reliable long-distance transmission . Duplex LC cables come with two connectors per end, often color-coded yellow for single-mode fibers, and may include zip-cord reinforced PVC jackets for durability .
Cable Construction
- Fiber Type: OS2 single-mode (9/125 µm)
- Jacket: OFNR (riser-rated) PVC, yellow
- Outer Diameter: Typically 2.0 mm
- Performance: Maintains light pulse fidelity over long distances, high bandwidth, low attenuation
- Testing: Fully inspected and tested according to ANSI/TIA/EIA standards
Applications
LC single-mode duplex cables are ideal for:
- Telecommunications networks
- Data centers and server farms
- High-speed Ethernet connections (1G–400G)
- Long-distance optical links where signal integrity is critical
Advantages
- High bandwidth and low attenuation for long-distance transmission
- Compact LC connectors allow high port density
- Durable construction with PVC jacket and reinforced design
- Lifetime warranty from reputable manufacturers ensures reliability These cables are widely available from suppliers such as FS, FiberCablesDirect, Mouser, and QSFPTEK, offering various lengths and connector configurations to suit different network setups .
