The discussion centers on the challenges of transmitting data over a 45 km length of multimode fiber optic cable without the use of repeater stations. Participants confirm that multimode fibers are inherently short-range and unlikely to support useful data rates over such distances. The conversation also clarifies that optical amplifiers cannot serve as repeaters in this context due to their power requirements. Alternatives such as microwave links are suggested for long-distance communication without repeaters.
PREREQUISITESThis discussion is beneficial for network engineers, telecommunications professionals, and system designers involved in fiber optic installations and long-distance communication solutions.

Are optical amplifiers repeater stations? How to get the signal to carry for 45 km? I read that multimode fibres are quite short-range.
