400G QSFP-DD DR4+ Silicon Photonics 1310nm 2km Transceivers
GIGALIGHT 400G QSFP-DD DR4+ silicon photonics transceiver is the enhanced version of the GIGALIGHT 400G QSFP-DD DR4 silicon photonics transceiver. It is also compatible with the IEEE 802.3bs 400GBASE-DR4 specification and supports 400G Ethernet links up to 2km over 4 pairs of parallel single mode fibers. Benefiting from the silicon photonics technology and parallel optics technology, it has become the most cost-effective solution for data center interconnection within 2km.
