 Product description Huatai H9122 product series, applicable to FTTx optical fiber switch-in network, as RFTV broadcast network's RX unit, it is a kind of high index, Low power consumption, high cost performance RFTV optical receiver.
This series products adopt high receiving sensitivity receiving tube and Huatai special low noise matching circuit Under 3.8% modulation, When transmitting in full channels and with receiving power of -10dBm, CNR still can reach high index of 45dB. It means that to meet the need of users45dB CNR, adopt to H9122 only need lesser optical power.
H9122 RFTV operating in 1210~1600nm wavelength.
H9122/WF: build-in channel filter, RFTV operating in1550nm wavelength.
H9122/WD: build-in CWDM, input wavelength 1550/1310, 1490. RFTV working wavelength 1550nm.Pass wavelength 1310/1490, connecting to GEPON ONU.
