Is the lc optical module a single port or two

Yes, an LC optical module can have a single port using a simplex LC connector.Single-Port LC ModulesLC connectors come in two main configurations: simplex and duplex. A simplex LC connector is designed for a single fiber, meaning it supports only one optical channel per connector . This allows an LC optical module to have just one port, which is suitable for applications where only unidirectional communication or a single fiber link is required . Simplex LC connectors are compact, with a 1.25 mm ferrule, making them ideal for high-density installations where space is limited .Duplex LC ModulesIn contrast, duplex LC connectors combine two LC connectors in a single housing, enabling bidirectional communication over two fibers simultaneously . Duplex LC is commonly used in standard SFP modules for Ethernet or data center applications, where both transmit and receive fibers are needed.Applications and ConsiderationsSimplex LC modules are often used in specialized or legacy setups, or in cases where only one-way communication is needed.Duplex LC modules dominate modern SFP deployments because most network links require bidirectional data transfer .Using a simplex LC module may require careful planning for network topology, as each fiber link will only carry a single signal direction.SummaryAn LC optical module can indeed have only one port if it uses a simplex LC connector. While duplex LC modules are more common for bidirectional communication, simplex LC modules are fully supported and useful in scenarios where a single fiber connection suffices . This flexibility allows network designers to optimize port density and fiber usage according to specific requirements.
