The Erbium Doped Fibre Amplifier Module (EDFAM) has been designed for MATV, CATV, FTTH and CCTV broadband applications. The EDFAM module forms part of the Light Link ® Series 3 family of products. This module utilises plug-and-play technology to provide a complete broadband and optical communications solution.
The output power available is from
20 mW to 250 mW (13 dBm to 24 dBm). Up to 80 mW a single pump laser is used. The larger EDFAM units employ dual pump lasers in a two-stage design with inter-stage isolators.
Light Link ® Series 3 is designed to extend a 1550 nm CATV system fibre without need to convert back to RF. Combined with our LTE152 externally modulated laser transmitters, system ranges of up to 100 km are possible.
The larger power EDFAM units find application in Fibre-To-The-Home (FTTH) systems, permitting many thousands of subscriber nodes to be supplied with signal from a single laser source. |
