Unpowered optical splitters enable a single fibre pair to serve up to 32 homes and businesses. The splitter itself is buried underground, fairly close to the premises being served, and is dedicated to that end user. The fibre connection back to the exchange is shared.
From the communications perspective, fibre means that you don’t get the distance-related degradation of service associated with copper. Moreover, as there are no active components with fibre, there’s nothing to go wrong in the normal course of events.Deployment of Fibre to the Premises in brownfield areas is going to be expensive, as it involves replacing the copper pairs running from customer premises. Availability will therefore depend on demand.
That said, BT will be deploying pilots at Highams Park, London, and at Bradwell Abbey, Milton Keynes, from the summer of next year. Together, they will pass around 40,000 homes.
For Fibre to the Premises rollout at greenfield sites, there’s no need to replace copper running from customer premises, as none existed in the first place! Deployment will therefore be less expensive than brownfield. However, availability is obviously going to depend on an upturn in the land development market.
