Raman pump source
FURUKAWA ELECTRIC
Descriptions
* ErFA 40000 series are Raman Pump Module (RPM) embedded EDFA gain block of the
signal wavelength band of 1529nm to 1562.5 nm. High power Raman pump unit is
suitable for long distance transmission, and also 100G network application to maintain
high OSNR. Integration of Raman & EDFA hybrid units realize low price by sharing of electrical interface, enclosure, and some optical components.
* The module can be controlled flexibly by fully software using RS232 communication interface.
