ntroduction
HHTX-1310 series transmitter. This series transmitter take the high linearity, the low noise of the distribution feedback laser (the DFB laser ). High in capacity transmission, low in non-linearity distortion. Adopt APC, ATC technology, achieved the transmitter output optical power’s stability. It offers AGC/MGC level adjustment functions.Under the AGC status, when the input RF signal changes in allowable range(±5dBmV), add to laser’s modulation level basicly invariable. Thus keep the system of CNR, CTB and CSO three big targets for a long-term stability .
Characteristics
• Operating wavelength 1310nm;
• The bandwidth 45-862 MHz, transmit 59 the PAL-D channel of TV singal and digital modulation signal;
• Use AGC、APC and ATC circuit, guarantee the modulation level & output optical power’s stability;
• RS232 industrial standard status monitor connection;
• High quality reliable switching power supply, may work in the 110~265VAC electrical network;
