You'll probably get an end-to-end fiber.
When the fiber is ready, youll get a measurement rapport with the distance
of the fiber and the attenuation. With this information you can buy your
optics.

For ethernet:

10GBase-LR - 10Km
10GBase-ER - 40Km
10GBase-ZR - 80Km


If the distances are bigger, you want SONET or specialized WDM optics.
We use MRV optics. They have optics that can transport Ethernet over 200Km.

Dirk-Jan
