Product Description
FTTH Digital TV Ultra-low Optical Receiver
H9122LG, H9122LG/WD, H9122LG/WF

Product description
Huatai Huatai H9122LG, operating bandwidth of 47 ~ 862MHz, is a suitable digital television FTTH applications, ultra-low optical receiver, it has a very high receiver sensitivity. Due to the built-in optical AGC, at high optical power receiver, played limiting output, so H9122LG in the received optical power over a large dynamic range of +2 dBm ~-21dBm, and have excellent properties.
H9122LG for Analog TV, in Pin =-10dBm when, Vo ≥ 82dBμ V, CNR ≥ 45dB.
H9122LG for Digital TV, in Pin =-16dBm when, Vo ≥ 80dBμ V, MER ≥ 36dB.
H9122LG for Digital TV, in Pin =-21dBm when, Vo ≥ 70dBμ V, MER ≥ 28dB.
Digital TV FTTH applications, the H9122LG can save a lot of optical fiber amplifier power resources. For operators, can greatly reduce the cost of building the network. Suitable for rural power digital TV, FTTH, triple play of wide application.
H9122LG optical port mode with following three types optional:
H9122LG: Operating wavelength 1260~1620nm.
H9122LG/WD: Built-in CWDM, suitable for single-fiber triple wavelength system, RFTV
Operating wavelength 1550nm, passwavelength 1310/1490nm, can conveniently connect the ONU of EPON, GPON.
H9122LG/WF: Built-in 1310/1490nm filter, suitable for single-fiber triple wavelength system, RFTV operating wavelength 1550nm.
