Kapil Sibal transfers telecom technology to manufacturers

New Delhi , Mon, 05 Dec 2011 ANI

New Delhi, Dec 5(ANI): Union Communications and IT Minister Kapil Sibal transferred a telecom technology, designed and developed by Centre for Development of Telematics (C-DOT) to telecom manufacturers here today.


Speaking on the occasion, Sibal said that Gigabit Passive Optical Network (GPON) is one of the game changer technologies after Nano and Akash during recent years.


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. (ANI)
