Silicon Photonics 400G QSFP-DD DR4+ 1310nm 2km Transceivers
GIGALIGHT's Silicon Photonics 400G QSFP-DD DR4+ optical transceiver modules are designed to support 400G Ethernet, suitable for data center links up to 2km over single mode fiber. The Silicon Photonics 400G QSFP-DD DR4+ modules are compatible with IEEE 802.3bs 400GBASE-DR4. The transmission side converts 8x 50G PAM4 electrical signals into 4x 100G PAM4 optical signal. Reversely the receiving side converts 4x 100G PAM4 optical signal into 8x 50G PAM4 electrical signals.
