Catvision Erbium Doped Fiber Amplifiers (EDFAs) use erbium and ytterbium co-doped double clad fibre technology. The no. of input & output optic ports and the power in each output port, is optional. Also optional is single or dual power supply (one as back-up), SNMP control and PON connectivity. All these options need to be specified at the time of ordering. They are designed with dual pump lasers that provides long term life and stable outputs with high C/N and low dispersion for extended range.

Main Features
