This product is FTTH (Fiber to the Home) optical receiver, with low power optical receiving, which can satisfy the demand of FTTH CATV receiving. It can separately and effectively receive 1550nm wavelength of CATV signal, with optical isolator, to satisfy the demand of only allowing 1550 wavelength received, and filtering out other wavelength optical signals.
The product is with compact structure, it is easy to install, and this is an ideal product for FTTH CATV network.

Block Diagram
Interface introduction
1. LED indicator for power supply. If power supply works normally, the LED indicator will be green; if fails or power off, the indicator will be off.
2. LED indicator for optical receiving power. When optical receiving power is higher than -12dBm, the LED indicator will be green. When optical receiving power is lower than -12dBm, the LED indicator will be red.
3. CATV optical input port: SC/APC.
4. RF output port. Use coaxial cable to connect with the RF input port of TV or STB.
5. Power input port. Connect with the attached power adaptor.
