Netscale LC-Duplex to MPO modules provide the interface between the male MPO connectors on the trunk and the LC-Duplex patch cords that will then connect directly into the transceiver modules. The LC-Duplex ports feature integrated laser shutters that move out of the way when the connector is inserted. R&M’s Type S LC-Duplex to MPO modules ensure correct fi ber polarity while requiring just one type of patch cord on both ends of the link. The crossover of the fi bers for duplex signal transmission takes place within the module.
