7 Indian players buy C-DOT's PON technology for broadband

New Delhi Dec 6 2011: Indian Minister for Communications and IT Kapil Sibal, has transferred Gigabit Passive Optical Network (GPON) Technology, designed and developed by Centre for Development of Telematics (C-DOT) to seven telecom manufacturers in public and private sectors – Indian Telephone Industries Ltd. (ITI), Bharat Electronics Ltd (BEL), VMC Systems Ltd, United Telecoms Ltd. (UTL), Sai InfoSystem (India) and S M Creative Electronics Ltd . In addition, Technology transfer agreement has also been signed with Tejas Networks Limited for customized development and Electronics Corporation of India Ltd (ECIL) is in the advance stage of this agreement.
Sachin Pilot,
Minister of State 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. Milind Deora the other MoS for C&IT also congratulated the entire telecom fraternity on the occasion.
The Telecom Equipment Manufacturers Association (TEMA) congratulated the Center for Development of Telematics (C-DOT) for developing the Gigabit Passive Optical Network (GPON) Technology. "The indigenously developed GPON technology vindicates TEMA's stand about the capabilities of Indian Research & Development and local manufacturing by Indian organizations. C-DOT has showcased its muscle in the field of R&D in the telecommunication arena, " said Ashok K. Aggarwal, Honorary Director General, Telecom Equipment Manufacturers Association.

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.
