CATV Erbium Doped Amplifier (EDFA)


CATV EDFAs inherit the reliable design of Amonics’s optical amplifier technology. They exhibit high output power, high gain with very low noise. They are thus ideal for CATV applications. CATV EDFAs are available in rackmount or module.

The turnkey rackmount CATV EDFAs provide microprocessor controlled alarms and status indicators. An integrated RS232 computer interface enables easy control, diagnostic functions and data acquisition.

The CATV EDFA modules, operated on a single +5V power supply, are ideal building blocks for OEM systems integration of a wide range of applications as they come with the essential EDFA functions to serve various purposes and the interfaces ready for system integration.

Amonics CATV Rackmount EDFA area made with high power pump laser and stability pump combiners, robust in high power boosting. The result are EDFAs that possess high output power, high gain with very low noise, and are ideal for CATV applications. The turnkey microprocessor controlled rackmount EDFAs manage alarms and status indicators. An integrated RS232 or Ethernet computer interface enables easy control, diagnostic functions and data acquisition.
