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. OverviewLC 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.

L

C 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 L

C 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.
