Network construction: underground

The most common method of laying cable in a rural network is underground. There are several different approaches that can be used get the cable underground between two points. One approach is to dig a trench, lay the cable, then backfill. The cable must be designed to last many years underground. The other approach also involves digging a trench, except that a duct is laid to protect the cable. Cables are usually blown into ducts by means of cable jetting.

From node to property

Micropipe is used as ducting from the last distribution point (property area node) to the actual property. The micropipe is normally laid in an excavated trench (pit). It is also possible to mill a groove into the ground and lay the cable in it, but this technique is normally used in built-up areas with asphalt roads and pavements. For the last section to the home, it is important to combine the installation with other potential users in order to reduce workload and costs. In terms of the workload, different organisations will have their own ideas, but the last section is usually handled by the relevant property owner.

Our approach to laying fibre cables underground is not based on proprietary techniques – instead, Nexans has products that are suitable for all environments.    

Linking the rural network (village network)

Starting with the home, the incoming fibre must always be terminated with an outlet. The operator provides the active equipment which converts light into electric signals (converter). A small fibre cable (microcable) is blown into the micropipe installed between the home and the distribution point. In the distribution point, the fibre in the microcable is spliced to a fibre in the multifibre cable running to the rural node. Each individual fibre is supplied with the services that have been purchased.

Broadband that's easy to install

Nexans products are easy to install and high in quality. There are products for entire run from the rural node to the home outlet. Nexans also works closely with duct and cabinet manufacturers in order to make all rural (local) network products quick and easy to install.

Everything for the rural (local) network

Nexans supplies home outlets, fibre cables, splice closures containing fibre splices in distribution points, and all cable handling parts for the fibres entering the rural node.
