RoW-management is integral in the deployment of optical infrastructure and can have direct consequences in the implementation-timelines. After being entrusted with the responsibility of a Project Implementing Agency (PIA) in phase 2 of the BharatNet project for Saurashtra-region in Gujarat, Polycab Telecom went on to complete the assignment with an efficient RoW approval process in the core.

BharatNet, with its ambitious aim to provide last-mile digital connectivity through the OFCs in more than 2.5 lakh Gram Panchayats (GPs) in India, has come a long way to facilitate Digital India-journey. Bihar, following the Public Sector-led model of BharatNet Phase-II, was divided into 3 Packages under the project. Polycab Telecom was awarded Bihar Package 3 (B3) to design and build the Digital Highway with Optical Fibres and maintain it for 6 years.

Undeniably fibre-optics technology carries the promise of a flexible, scalable and full-service network platform, enabling the service-providers to transmit massive amounts of information at record-breaking speeds, with minimal interference. But laying of optical-fibre cables comprises processes and procedures which, when not strictly adhered to, could be a potential threat for the environment.

Today Dense Wavelength Division Multiplexing (DWDM) is one of the most frequently applied fiber-optic transmission technologies to build core telecom networks. DWDM is an optical multiplexing system, wherein data-signals from varied sources are put together, with each signal being transmitted on a separate light wavelength. More than 80 separate wavelengths, each about 0.8 of a nanometre-wide, can share a single optical fiber.
