>> in general to have double the amount of bandwidth, you have double the cable laying effort. Getting double the bandwidth just means laying a slightly thicker cable, and I do mean slightly. Adding a bundle of extra fiber when laying a cable adds maybe a millimeter to the cable width. The cost of the fiber is almost irrelevant to the cost of the other layers and the effort of placing it. Most cables are therefore laid with plenty of extra "dark" fiber for later expansion/redundancy. |
