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.

Coherent optical module refers to a typically hot-pluggable coherent optical transceiver that uses coherent modulation (BPSK/QPSK/QAM) rather than amplitude modulation (RZ/NRZ/PAM4) and is typically used in high-bandwidth data communications applications. Optical modules typically have an electrical interface on the side that connects to the inside of the system and an optical int. Many different forms of optical modulation and multiplexing have been employed in coherent optical modules.

All three of the these methods use the same final calculation: cable length x twist factor. This Applications Engineering Note (AE Note) addresses estimating cable length or event distance using an optical time domain reflectometer (OTDR). This method takes the length of the cable as drawn in the GIS and adds any length stored in slack loops, risers, or other point features. There are a number of ways to tackle the problem of determining the power requirements for a particular fiber optic link.
