GIGALIGHT 400G DR4 Silicon Photonics Transceivers
29th March 2023
GIGALIGHT 400G QSFP-DD DR4 silicon photonics transceiver is compliant with the IEEE 802.3bs 400GBASE-DR4 specification and supports 400G Ethernet links up to 500m over 4 pairs of parallel single mode fibers. It can convert eight 50G PAM4 electrical signals into four 100G PAM4 optical signals and reversely convert four 100G PAM4 optical signals into eight 50G PAM4 electrical signals to achieve 425Gb/s full-duplex transmission. Benefiting from the silicon photonics technology, it has become the most cost-effective solution for data center interconnection within 500m.
