Dual-core LC optical module

A dual-core LC optical module is a fiber optic transceiver that uses a duplex LC connector to enable simultaneous bidirectional data transmission over two fibers.OverviewA dual-core LC optical module integrates two LC (Lucent Connector) interfaces in a single compact housing, allowing one fiber to transmit optical signals (TX) and the other to receive signals (RX) simultaneously . This design supports full-duplex communication, which is standard for Ethernet and telecom optical links. These modules are widely used in SFP, SFP+, and SFP28 transceivers, providing high-density connectivity in data centers and enterprise networks .Key FeaturesConnector Type: Duplex LC, with a 1.25 mm ceramic ferrule for precise fiber alignment .Fiber Compatibility: Supports both single-mode fiber (SMF) and multimode fiber (MMF) systems .Data Rates: Commonly available in 10G SFP+ modules for 10 Gigabit Ethernet, and higher-speed QSFP modules for 40G or 100G links .Wavelengths and Reach: Typical single-mode modules operate at 1310 nm with distances ranging from 10 km to 20 km, while multimode modules may support shorter distances like 2 km .Hot-Swappable: Most modules are hot-swappable, allowing easy installation or replacement without powering down the network device .ApplicationsDual-core LC modules are used in:Data centers for high-speed server interconnects.Telecom networks for reliable long-distance optical links.Enterprise backbone networks to support 10G, 25G, 40G, or 100G Ethernet connections.Migration solutions where existing duplex fiber infrastructure is reused for higher-speed links, such as upgrading from 10G to 40G or 100G Ethernet .AdvantagesCompact form factor suitable for high-density port layouts.Reliable full-duplex communication with low latency and high stability .Flexibility to work with both single-mode and multimode fibers.Ease of deployment due to standardized SFP/SFP+ interfaces and hot-swappable design. In summary, a dual-core LC optical module is a versatile and essential component for modern high-speed optical networks, providing efficient, bidirectional data transmission over two fibers while supporting a range of speeds, distances, and fiber types .
