The QSFP28 100G muxponder is a 12-channel 10G or 24-channel 10G Ethernet signal aggregator to meet broadband optical transmission and data center links.It follows the G.709 protocol multiplexing mapping and framing processing. After the 100G PAM4 optical module completes the photoelectric conversion into 100G signal, to realize the 10G signal input and output. Provide high-quality solutions for transmissions such as insufficient margins of the existing systems and long optical cable transmission distances.
