product description
 
  H9122L-4FE is a three-network, fiber-to-the-home ONU optical network unit. The product integrates a high performance CATV FTTH optical receiver and EPON ONU in an ultra-small metal case. It can provide users with high-quality CATV and high-speed data, language, video and other broadband business services. The high performance, high compatibility, and excellent performance-price ratio of the products are the preferred devices for today's three-network convergence and fiber-to-the-home.
 
  H9122L-4FE, built-in EPON ONU, can provide users with 4 10M/100M Ethernet ports. The product implements the interoperability standards of the Ministry of Industry and Information Technology, and is compatible with EPON OLTs of multiple manufacturers to achieve interconnection and interoperability.
 
  H9122L-4FE, built-in CATV optical receiver, H9122L with high sensitivity and ultra-low light reception. The digital TV fiber to the home, using the H9122L-4FE, can greatly save the optical power resources of the fiber amplifier. For operators, the cost of building the network can be greatly reduced.
 
  H9122L-4FE optical port mode, there are two types of selection:
 
  H9122L-4FE-SF: Single fiber access, built-in CWDM, suitable for single-fiber three-wave system.
 
  H9122L-4FE-DF: Dual fiber access, without CWDM, one fiber for CATV and data.
 
Features
 
CATV optical receiver
 
1. Ultra-low noise, used for analog TV, when Pin=-10dBm, Vo≥86dBμV, CNR≥45dB
2. High receiving sensitivity for digital TV, when Pin=-16dBm, Vo≥82dBμV, MER≥36dB
3. The received optical power has excellent characteristics in the large dynamic range of +2dBm~-22dBm.
4. Can save a lot of optical power resources and greatly reduce network construction costs

EPON ONU
 
1. Powerful L2 switching function
2. High-rate PON: uplink and downlink symmetric 1Gb/s data, VoIP language and IPTV
3. For ONU automatic identification, ranging, configuration, ONU can be “plug and play”
