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

FIBERSTAMP 400G QSFP-DD DR4++ Silicon Optical Module extends the reach of DR4 for longer transmission distances. Compliant with IEEE 802.3bs 400GBASE-DR4, it supports 400G Ethernet rates (425Gb/s) for full-duplex links covering distances up to 10km. Leveraging the cost efficiency of silicon optical technology and the low device cost of single-lambda 100G PAM4 modulation and parallel optical engine technology, this module stands as a highly cost-effective solution for 400G interconnects within data centers
