An optic fibre cable has much more fibers 123 per cable, such as even 1,000 or 10,000 times more than what is being done today, with an increase in cost that is orders of magnitude smaller. The cable may contain multi-fiber flexible flat jackets that can move freely within a cable's pipe 121, preferably with the pipe divided into at least two cells, so that it can bend only in the desired direction and have maximum structural strength. A rolled, flat, flexible jacket 122c of eg. 20,000 fibres 123c and a flexible, multilayer structure 122d are shown. Another important feature is various methods for optimizing the efficiency of amplifying multiple fibers simultaneously. Another important feature is significantly reducing the cost of the end-equipment by duplicating each lambda into multiple fibers and on/off modulating it separately for each fiber, so that much less laser sources are needed. |
