The Centre for Development of Telematics (C-DoT) on 5 December 2011 transferred indigenously-developed Gigabit Passive Optical Network (GPON) technology to seven telecom equipment manufacturers, including private players. The GPON technology was transferred to the telecom equipment manufacturers to give the much-needed push to broadband penetration in India.
The government transferred this technology to seven manufacturers in public and private sectors — ITI, Bharat Electronics, VMC Systems, United Telecoms, Sai InfoSystem (India), SM Creative Electronics. Transfer of technology was also signed with Tejas Networks for customised development.
GPON technology
The GPON technology is a pivotal component required for broadband connectivity over optical fibre.
C-DOT indigenously designed and developed GPON technology, which can be used to provide triple play (voice, video and data) through fibre-based networks. 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, the large data carrying capability is important for Indian villages too where prevailing low literacy levels will require better dissemination of information with greater graphic and audio content. Besides, voice telephony, high speed Internet access and IPTV, the C-DOT GPON has provision to carry cable TV signal too.
The GPON technology was tested, validated, field-evaluated and made operational in BSNL's network in Ajmer (Rajasthan). The technology will help fulfil requirements of major national programmes like the National Optical Fibre Network and the State Wide Area Network.
