Abstract
25G BiDi, 50G 4-level pulse amplitude modulation (PAM4), low-cost coherent 100G are the typical examples of the transceivers demanded by the 5G wireless front-haul and back-haul networks. Low cost is the primary requirement for the 5G wireless transceiver. Specification classification, utilization of the off-the-shelf components, technology innovations, and made-in-China components are the main means to achieve low cost. The key technologies of the 5G wireless transceiver are all about the optoelectronic chips, and the innovation in optoelectronic chips can be carried by the extension of the functionality, the upgrade of the bandwidth, and the low-cost approach.
