Designed for long-reach 200G Ethernet applications, QSFP56 FR4 optical transceiver uses 1310nm wavelength to achieve stable 2km transmission. With duplex LC/UPC interfaces, its compact form factor supports high-density deployment. The built-in DOM function supports remote monitoring and fast fault diagnosis, greatly simplifying network maintenance. By testing in switchs, optical transceiver guarantees excellent performance, quality, and reliability.
