H9122L-4FE, built-in EPON ONU, providing users 4 10M/100M LAN ports . Product implementation of the national Ministry of interoperability standards , compatible with multiple manufacturers of EPON OLT, to achieve interoperability .
H9122L-4FE, Built-in CATV optical receiver, high sensitivity, ultra light received H9122L.FTTH digital television, H9122L-4FE can be used to save a large amount of optical fiber amplifier power resource . For operators , can greatly reduce the cost of building the network.
H9122L-4FE optical port mode, there are two kinds of selection:
H9122L-4FE-SF: single fiber access , built-in CWDM, applicable Triplexer wave
system .
H9122L-4FE-DF: dual fiber access, without CWDM, CATV and data each with an
optical fiber.
Product feature  Digital TV optical receiver
1. Ultra-low noise, for analog TV,When Pin =-10dBm, Vo ≥ 86dBμV, CNR ≥ 45dB
2. High receiver sensitivity for digital television,while at Pin =-16dBm, Vo ≥ 82dBμV,
MER≥ 36dB
3. Received optical power over a large dynamic range of +2 dBm ~-22dBm,and have
excellent properties
4. Optical power can save a lot of resources, greatly reduce the cost of network
construction
EPON ONU
