1)TV EDFA Amplifier is a kind of 1550nm optical wavelength signal transmitting equipment for HFC broadband. 2)with best price TV EDFA Optical Indoor Amplifier is a kind of 1550nm optical wavelength signal transmitting equipment for HFC broadband transmitting network.Using direct modulate,on the demand of low operation input RF signal level,ensures it for the front of the channel.Under 860MHz.It can transmitTV signal and INTERNET digital signal.With MPU circuit,to control the working status of the Laser,it will display in the VFD on the front panel, inside double power supplies,switch automatically(backup power). Excellent non-linear can ensure products buildup multilevel fiber net,achieve the use-rsbestrow In a distance.it also can use RS232 for distance control.Features:(1) 980nm/1480nm pump laser optional.(2) High gain and power makes the products have a low noise figure.(3) output optical power: 14~23dBm.(4) CPU monitor the status,VFD display the status,customercan test parameters at any time.(5) RS232/485 interface, for network managment function.inside double power supplies, switch automatically(backup power).(6) 19 inch 1U design for installation.Electric Parameter:
