Regarding optical chips, the industry is more optimistic that the 50Gbit/s PAM4 module will become the mainstream application module for mid-haul and future PON network upgrades. At present. In order to support the diversity of services, in the 5G transmission network architecture, fronthaul, midhaul, and backhaul networks may be equally important. Among them, the prequel is from RRU to DU (the distance is generally within 10km, a few scene is within 20km; among them, to deal with the scene with high delay requirements, the transmissio. Table 2 lists the mainstream specification requirements for high-speed optical transceiver modules in the 5G transport network. Large bandwidth, small size, low power consumption and low cost have become the basic characteristics of the development of optical module technology. 5G base station interconnection optical modules are mainly upgraded fro.
