1310 кабельного телевидения передатчик

The optic transmitter AOT-03, with 19 inch 1U rack-mount, adopts newly developed whole-band frequency pre-distortion circuit. Comparing with traditional pre-distortion circuit, it takes advantage of improving non-linear parametersCTB≥68dB , CSO≥66dB, meanwhile, as a result of signal without delay and will not drift with temperature, it enhances stabilities during signal transmitting; With the help of high performance DFB laser and microprocessor technology, AOT-03 transmitter operates with wide frequency bandwidth, big transmission volume, non-linear and low distortion characteristic; The working status of DFB laser monitored by microprocessor displays on the front panel.
