OPGW as a communication medium has some advantages over buried optical fiber cable. Installation cost per kilometre is lower than a buried cable. Effectively, the optical circuits are protected from accidental contact by the high voltage cables below (and by the elevation of the OPGW from ground).
(dB) ≈ 36.6 dB + 20 log10[frequency (MHz)] + 20 log10[distance (miles)] These alternative forms can be derived by substituting wavelength with the ratio of propagation velocity ( c , approximately 3 × 10 8 m/s ) divided by frequency, and by inserting the proper conversion factors between km or miles and meters, and between MHz and (1/s).
Wireless backhaul is easy to deploy, cost efficient and can provide high capacity connectivity, e.g., multiple gigabits per second, and even tens of Gbps. Wireline fiber backhaul, on the other hand, can provide practically endless capacity, but requires investment in deploying fiber as well as in optical equipment.

Although fiber-optic systems excel in high-bandwidth applications, the last mile problem remains unsolved as fiber to the premises has experienced slow uptake. However, fiber to the home (FTTH) deployment has accelerated. In Japan, for instance EPON has largely replaced DSL as a broadband Internet source. The largest FTTH deployments are in ...
