The following are general guidelines and recommendation on which fiber and cable to use where in the Network.

Long distance Network:

i. A minimum of 96 fibers (impact on power towers in regards to weight and wind-torch when not direct buried to be considered).

ii. Fiber to confirm to ITU-T recommendation G.652 D as it is more economical and provide better power budget than corresponding NZDS fiber. If dispersion is the major concern fiber should confirm to ITU-T recommendation G.656 (mainly for non-coherent transmission up to 10 Gb/s). For new evolving coherent transmission standards (40-100Gb/s) the more economical G.652 D have better generic prestanda. To accommodate for both systems a mixed fiber cable having 48xG.652 D fibers and 48xG.656 can be deployed.

Metro and Access (including feeder and distribution):

i. Minimum 96 x ITU-T recommendation G.652 D fiber cable suitable for micro-duct installation.

FTTH (drop cable)

i. If needed from a bending perspective the latest suitable G.657 A release or corresponding should be used otherwise G.652 D. Supplier to consider applicable bend losses.

Indoor
