with Sat-If Input Optical Amplifier EDFA (HA4600/IF)

HA4600/IF
SAT-IF Optical Amplifier

Product description
AITC HA4600/IF series, is narrow-band multiplexing EDFA suitable for L-Band fiber link application. With build-in 1550nm Internal Modulation SAT-IF optical transmitter, used for inter-cutting DBS. The WDM inside will multiply the signal from TX and main line signal that is inputted from outside, then the combined signal will enter EDFA to be amplified to serve the local subscribers. To avoid the interferes caused by mismatching of the optical output power between TX and main line signal from outside, output power of the TX can go through a VOA, thus, it can be adjusted or set from the front panel. This unit is simple and clear, easy to be installed and tested. It offers a high quality and cost-effective solution for inter-cutting DBS into full optic relay 1550nm fiber CATV system and second-stage service area.
