FTTH Digital TV Ultra-low Optical Receiver
Product description
AITC H9122L is an FTTH Digital Tv Ultra-low Optical Receiver which is suitable for digital TV Fiber to the Home (FTTH) application. It has extra-high receiving sensitivity, used for digital TV; when the receiving optical power is -22dBm, MER≥28dB. With high optical power receiving, it will adjust the level via PAD to limit the output, so the H9122L can have excellent feature within the wide dynamic receiving optical power range +2dBm~-22dBm.
Digital TV, FTTH application, if adopts H9122L, can save a large number of optical power resource, For operators, it can greatly reduce the network construction cost. which is suitable for the application of village network, digital TV fiber to the home, and triple network integration.
