Irish Gov't Invests In Color-Coded Fiber Optics

c0mpliant writes "The Irish government has invested a further €5 million, after already having invested €5 million one year ago, in a new system of fiber optics which heralds an era of virtualization of fiber networks, using color coding to enable multiple fiber providers to serve businesses and homes, often on a single strand of fiber. The technology, which has already sparked interest from companies such as BT and IBM, is already in its first phase and boasts an impressive 2.5 terabytes capacity, double the capacity of the London phone system. The company behind the technology, Intune Technology, is comprised of a group of ex-UCD photonics researchers and has been around since 1999 and are based in Dublin. The project is set to be completed by 2020."

Terminology

[fridaynightsmoke]

I assume that by 'colour coding' what the summary actually means is Frequency Division Multiplexing, which isn't exactly new.

Reading TFA it looks to me like a situation of "we've 'invented' this amazing technology, give us money". That may be unfair I admit. What IS interesting is the idea of the fibre being shared by competing telcos. Has that been done before?

Yes, it has. Selling wavelengths in dark fiber is very common, and companies frequently buy part of lines from eachother. Submarine cables are frequently owned by several companies.

On a level closer to the customer there exists a (in Sweden) functional business model where a company owns the line to the customer and creates a market where different ISP's can provide services to the customer. OpenNet is one of more well known providers using this business model in Sweden.
