Addressing the Dark Fibre of FPGA-Based Prototyping, Lighting the Dark FPGA'sBreaking the Three Laws - Michael PosnerOct. 19, 2015 |
The term “Dark Fibre (Fiber) refers to the additional lines/capacity of optical connections a carrier would install when they laid a new pipeline. These unlit optical connections were built in assuming the need for additional capacity in the future. The thinking was that it’s cheaper to do it all at once vs. adding lines/pipelines later. The problem is that this extra capacity is going to waste and while the main carrier was not using it, someone else could have.
(There is no difference in meaning between the word fiber and fibre. Fiber is the preferred spelling in American English, and fibre is preferred in all the other main varieties of English and as I am originally from the UK I’m ignoring spell check and using the fibre spelling)
