C'est un scan en gros plan d'une « fibre noire » composé de 144 fibres optiques monomode d'une capacité nominale de 2,5 Gb/s. Ce type de fibre est enterré sous terre pour former des réseaux à l'échelle métropolitaine voire internationale.

Celle-ci est utilisée entre autres sur le réseau Pau Broadband Country.

This image has currency in it to indicate scale. Using coins for scale is discouraged as it will require people unfamiliar with them to look up the dimensions or guess, both of which defeat the purpose of the object in the first place. Coins can also reinforce a geographical bias, and some coins' designs are copyrighted. Ideally, a photograph should include a ruler with the subject (example) or an added scale marking. SI ("metric") units are the most commonly used worldwide (see meter and centimeter).
