Gigabit Passive Optical Network (GPON) technology indigenously designed and developed by the Centre for Development of Telematics (C-DOT), will be transferred to manufacturers. GPON technology is the pivotal component required for broadband connectivity over optical fiber. The GPON technology has been tested, validated, field evaluated and then became operational in the BSNL Network at Ajmer, Rajasthan and is being transferred to seven public and private manufacturers. Thus, a requisite production infrastructure has been set-up for state-of-the-art technology manufacturing in the country with associated eco-system through a comprehensive C-DOT Transfer-of-Technology Package, which have been the hallmark for converting R&D concept from lab-to-manufacturing and then to the field deployments to fulfill the objectives of NTP-2011.
The C-DOT GPON technology is appropriate and well suited for Indian environment. It is targeted for fiber expansion in the country to fulfill the requirements of major national programs such as NOFN (National Optical Fiber Network), SWAN (State-Wide-Area Network) connectivity, Broadband connectivity in Rural, North-East, Tribal areas, as well as expansion of networks of Defence, Railways Networks on optical fiber and many other strategic networks.
C-DOT GPON can be used to provide a future proof broadband solution to village panchayats and take the benefits of e-Education, e-Governance, e-Commerce and e-Medicine etc., in fact a whole gamut of e-services, to our rural and urban populace with all its attendant empowerments and multiplier effects leading to a significant growth in the GDP.
Centre for Development of Telematics (C-DOT) established in the year 1984, under Ministry of Communications & IT is an autonomous R&D telecom technology centre. It was set-up by the Government to develop state-of-the-art telecom technology to meet the needs of the Indian telecom network. For the last 27 years C-DOT is engaged in its R&D efforts in the indigenous design, development and production of telecom technologies for Indian environment
Besides, C-DOT is also working on other several important, cutting edge technologies, namely Broadband Rural Wireless System, Next Generation Networks (NGN), SG-RAN (Shared GSM Radio Access Network), Security Programs - Centralized Monitoring System (CMS), Secured Data Communication Network (SDCN) etc. which are also appropriate to meet the immediate country requirement of broadband infrastructure creation, security and bridge divide between urban and rural on the platform of digital economy. These technologies have been field tried and operational in the network as pilot.
Prior to C-DOT establishment, the mission of achieving connectivity and reliability seemed a mirage till early eighties with 1.5 million telephone lines in the network comprising predominately electromechanical exchanges, particularly in rural. C-DOT in all these years had been in the technology forefront and significantly contributed in the Indian Telecom Network digitization, bridging the digital divide between urban and rural, establishing strong telecom manufacturing infrastructure and employment generation.
Shri Kapil Sibal,Union Minister for Communications and IT transferred this Telecom Technology, designed and developed by Centre for Development of Telematics (C-DOT) to telecom manufacturers. Speaking on the occasion Shri Sibal said that Gigabit Passive Optical Network (GPON) is one of the game changer technologies after Nano and Akash during recent years.
Shri Sachin Pilot, MoS for C&IT expressed hope that GPON technology will not only provide safe and secure communication environment but will also mitigate the cost of communication. It was in his constituency Ajmer where C-DOT partnered with BSNL last year to try and test GPON technology successfully on pilot basis. Shri Milind Deora the other MoS for C&IT also congratulated the entire telecom fraternity on the occasion.
Gigabit Passive Optical Network (GPON) technology is the pivotal component required for broadband connectivity over optical fiber. C-DOT has indigenously designed and developed GPON technology, which can be used to provide triple play (voice, video and data) through Fiber based services (FTTX). It consists of a central office equipment OLT (Optical Line Termination) and customer premises equipment called ONT (Optical Network Termination). The information from central office to the customer premises and back, flows through optical fiber cable, which is essentially a light pipe. Light energy flows through this pipe and carries large amounts of data. The information carrying capacity of an optical fiber is practically limitless. The present GPON standards specify 2.5 Gbps (Gigabit per Second) downstream and 1.25 Gbps upstream data capability to customer premise.
Apart from urban areas, especially multi-dwelling units, the large data carrying capability is important for Indian villages too where prevailing low literacy levels will necessitate information with greater graphic and audio content for better dissemination.
Besides, voice telephony, high-speed Internet access and IPTV, the C-DOT GPON has provision to carry cable TV signal too, all on a single optical fiber. Another important advantage of GPON is that it can carry information from a central office to subscribers up to 60 Km away without needing any intermediate repeaters thus doing away with the requirement of power, shelter and upkeep services at the intermediate locations.
The GPON technology has been tested, validated, field evaluated and then became operational in the BSNL Network at Ajmer, Rajasthan. The technology is now being transferred to seven manufacturers in public and private sectors - M/S Indian Telephone Industries Ltd. (ITI), Bharat Electronics Ltd (BEL), VMC Systems Ltd, United Telecoms Ltd. (UTL), Sai InfoSystem (India) Limited, S M Creative Electronics Ltd. In addition, ToT has also been signed with M/s Tejas Networks Limited for customized development and Electronics Corporation of India Ltd (ECIL) is in the advance stage of agreement.
With this transfer, a requisite production infrastructure has been set-up for state-of-the-art technology manufacturing in the country with associated eco-system through a comprehensive C-DOT Transfer-of-Technology Package, which have been the hallmark for converting R&D concept from lab-to-manufacturing and then to the field deployments to fulfill the objectives of NTP-2011 which aims to provide a secure, reliable, affordable and high quality converged telecommunication services in the country. The policy, therefore, has given major thrust for Broadband on Demand, R&D for Indigenous Technology Development and Indigenous Manufacturing to achieve self-reliance in Telecom / ICT equipment design and manufacturing.
