The EMCORE PONA 2100 Series Erbium Doped Fiber Amplifier (EDFA) is an ideal building block for OEM system integrators. The family of PONA 2100 series EDFA’s is designed to meet the most demanding noise performance requirements of CATV applications, and performs all the functions required of an optical amplifier for system integration. Packaged in a convenient 1 RU housing, the PONA 2100 series EDFA’s provide optical isolation on the input and output of the gain block for stable, low noise operation. The input and output optical signal power levels are detected for monitoring and control. The input optical signal is amplified with active gain control for a constant output power level, or with active output power control for constant gain mode. The PONA 2100 series EDFA’s also provide monitors and associated alarms for all vital characteristics. The optical output of the PONA 2100 series EDFA’s can be split into multiple ports by an optional external splitter.
