Development Trends of Fiber Optic Communication WDM Technology

This paper presents an overview about WDM technology and recent developments in this field and how the overall capacity of the communication network can be incremented using this technology. Keywords – bandwidth, multiplexing, optical network unit, OCDM, passive. WDM is a technique that enables multiple optical signals to be transmitted over a single fiber optic cable, each at a different wavelength. The application fields of wavelength division multiplexing (WDM) integrated devices are continually expanding.

5G Optical Module Concept

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. 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.
