ium-doped Fiber Amplifier (EDFA)
Salient Technical Features
EDFA is a key component for Specifications fine-tuned for
community antenna television
(CATV) and fibre-to-the-home application in CATV and WDM;
(FTTH) technology. The CSIR-CGCRI
technology in this regard, developed operating wavelength of 1540-1530
in partnership with industry, comprise
of specialty optical fibre and a series nm for former and C-band region
of electronic input with controls
which can be fitted intermittently for the latter; output power ranging
along optical cable fibres. It restores
energy loss during transmission and from 20-23 dBm and 18-20dBm
ensures high quality pictures, sound
and connectivity. respectively.
Intellectural Property Rights (IPR) : State of Commercialization
Patented Commercialized
Major Raw Materials Utilized
Er-doped fibre, 976nm pump laser
diode, driver and controller for pump
laser diode, WDM coupler and isolator
Level/Scale of Development : Major Plant, Equipment and
Available for licensing Machinery Required
Application Tunable laser source at C-band,
optical spectrum analyser, power
Cable TV, optical communication meter, splicing machine
systems; application in the telecom
sector
