One of fibre-optic cable’s benefits is that it has the highest possible information transmission capacity among all communication cable types with a relatively small cable diameter of typically less than 20 mm (0.8 in.) The main deterrent in deploying fibre cable is the requirement to convert electrical communication signals to optical signals using fibre-optic transceivers. This adds complexity and cost to the communication systems. However, optical transceiver pricing has dropped considerably over the years; this cost can be minimal compared to the overall benefit of fibre-optic cable deployment.
