The Tata Group's broadband enterprise operates as a division of Tata Power, India's largest private energy company. The backbone of this venture — called Tata Power Broadband — is a 600-km fibre-optic network spread across Mumbai and Pune.

The technology powering Tata Broadband is DWDM, or dense wavelength division multiplexing. This technology increases bandwidth over existing fibre-optic cable by multiplexing (communicating two or more signals over a common channel) several optical signals onto one fibre, thereby increasing its load-carrying capacity manifold.

Tata Broadband has brought the latest DWDM technology, with gigabit IP switching, to India. No other carrier in the country has
DWDM in a 'metropolitan area network' (MAN). This makes India the second country in Asia, after Japan, to exploit this technology in a MAN.

Tata Broadband has positioned itself as a carrier's carrier. What this means, basically, is that Tata Broadband will be delivering its services to other service providers, such as Internet service providers, cellular services providers, national and long-distance telephone operators, data centres, call centres, cable operators and video service providers.

Tata Broadband's fibre-optic network was completed in August 2001. This was a mammoth task that required expertise and focus of a high order (it helped that the Tatas have over 70 years of experience in laying underground cables). Currently the division has over 50 customers, among them some of India's best-known service providers. Tata Broadband's knowledge partners in this venture are Cisco and Sycamore.

The Tata Broadband network offers a wide range of outstanding services, from co-location and network management to comprehensive access options for varying client needs and technologies. Its offerings include:
Virtual fibre / wavelength services
Time division multiplexing (TDM) capacity dedicated to customers
IP services
Co-location

Tata Broadband's goal is to become India's leading carrier's carrier. It already delivers standout competitiveness in quality of service and cost. It does this by offering its customers unequalled network quality, top-quality support and effective contingency management.
