 Product description Huatai H9222L, operating bandwidth of 47 ~ 862MHz, is a suitable digital television FTTH applications, ultra-low optical receiver, Whether used in analog television or digital television. Receiving at high optical power can be adjusted by PAD level, played limiting output, so H9222L within a large dynamic range of the received optical power of +2 dBm ~-20dBm, have excellent characteristics.
H9222L for Analog TV, in Pin =-10dBm when, Vo ≥ 68.0dBμV, CNR ≥ 45.2dB.
H9222L for Digital TV, in Pin =-15dBm when, Vo ≥ 66.0dBμV, MER ≥ 36.2dB.
H9222L for Digital TV, in Pin =-20dBm when, Vo ≥ 55.7dBμV, MER ≥ 28.1dB.
Digital TV FTTH applications, the H9222L 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.
H9222L optical port mode of the following three selection:
H9222L : operating wavelength 1260~1620nm.
H9222L/WD: built-in CWDM, suitable for single-fiber triple wavelength system, CATV
operating wavelength 1550nm, pass wavelength 1310/1490nm, can
conveniently connect the ONU of EPON, GPON.
H9222L/WF: built-in 1310/1490nm filter, suitable for single-fiber triple wavelength
system CATV operating wavelength 1550nm.
