SiPh 400G QSFP-DD DR4++ 1310nm 10km Optical Transceiver

GIGALIGHT 400G QSFP-DD DR4++ Silicon Optical Module is an enhanced version of DR4 that supports longer transmission distances. It is compliant with IEEE 802.3bs 400GBASE-DR4 specification and supports 400G Ethernet rate (425Gb/s) full duplex links up to 10km. With the advantage of high-quality signal and low mass production cost of silicon optical technology, as well as low device cost of single-lambda 100G PAM4 modulation technology and parallel optical engine technology, this product is now one of the most cost-effective solutions for 400G interconnect within 10km of data centers.
