Traditional communication networks are based on simulated data and implemented with copper cables. However, with the rapid progress of technology, the transmission rate of the network must be increased accordingly. Today, copper cables are gradually being replaced by modern optical fibers.How has fi

This question is a bit broad and can include the following two main branches, 1. The optical fiber coverage of the backbone network (long haul and metro network), and 2. The optical fiber coverage of the access network (access network). In contrast, the questioner may be more concerned about the acc

fiber to the home"The current network uses optical fiber", this sentence is correct, but it is only fiber to the home. Fibers have lower losses when transmitting signals over long distances. From the optical cat in our house to the operator's control room, all network signals are transmitted by opti
