400G QSFP-DD FR4 2km Duplex LC/UPC Optical Transceiver Module
The 400G QSFP-DD FR4 is a high-performance optical module designed for long-haul transmission in data centers and enterprise networks. The module is available in QSFP-DD package form and complies with the QSFP-DD MSA and IEEE 802.3cu 400GBASE-FR4 Ethernet standards, supporting data transmission over single-mode fiber (SMF) over a maximum distance of up to 2km.
The module works by converting eight 53.125Gb/s electrical signals into four 106.25Gb/s optical signals and multiplexing them into a single optical signal for transmission via CWDM technology. The receiving end then demultiplexes the input 400Gb/s optical signals into 4 optical signals and converts them back into 8 electrical signals. The module adopts duplex LC connector, supports hot-swap function, and consumes less than 10W.
