1. FTTH CATV optical receiver
2.2 output ports
3. Input optical power: -2~7dBm
SHG OR-860LH-II series optical receiver is a kind of lastest practical CATV network product designed according to our full research to market. This mahine adopts GaAs MMIC amplifing component combined with amplifing module, optimizing the circuitry design to make its output have better performance index when input optical power is in the range of -8~+2dBm. Output attenuation and equalization are adjustable, which makes CATV network project very convenient to debug. Digital and analogue signal can be transmitted at the same time. It is the priority of current HTTP network system construction.
