Reliance infocom has built a national wide optic fiber based network infrastructure optic fiber was chosen as the preferred transport medium for reliance infocom, because of its undue advantages as compared to copper for carrying high data rates.

The network infrastructure spans 60,000 kilometers of optic fiber cable 250,000 kilometers of high-density polyethylene ducts and 30,000 kilometers of other cables.

The fiber to the building (FTTB) architecture is achieved through the access network. It enables end users to connect to the large telecommunication network. One of the most Interesting feature is the access node employed entitled digital loop carrier.

Reliance network has also introduced a new broadband technology employed in the copper access network entitled Digital subscriber loop.

The access network is functioning on the bases of protocol suite entitled V5 protocol.

Use of synchronous Digital Hierarchy (SDH) is within the city and Dense Wavelength Division Multiplexing (DWDM) for the national backbone ensures reliability, fast restoration from failures and low probability of outages. Use of several self-healing rings enables a high quality of service.

The Centralized Administrator of the entire Broadband Network through central Network Access center is one of the main features introduced in reliance architecture
