CATV FTTP optical receiver/ Optical node
Product description
Huatai FTTP CATV receiver node P1228 product series, 47~1200MHz operate bandwidth, output level Vo=92dBμV ( Pin=-2dBm, PAD=4dB ), suitable for FTTP,FTTH optical fiber access network, which is a low power consumption, high performance, and excellent cost performance RFTV broadcast network ONU(Optical network unit ).
This series product adopts high sensitivity receiving tube and Huatai special low noise matching circuit. Under 3.8% modulation, when transmitting in full channels and with receiving power of -8dBm, the CNR can still reach high index of 45dB. Therefore, if adopting P1228, it is only need very low optical power to reach 45dB CNR required by the user.
P1228 optical port mode with following three types optional:
P1228/NC:RFTV operating wavelength 1260~1620nm.
P1228/WF:Build-in 1310/1490 filter, RFTV operating wavelength 1550nm.
P1228/WD:Build-in CWDM,RFTV operating wavelength 1550nm, pass
wavelength 1310/1490nm, ( Link EPON,GPON ONU ).
Main application
- FTTP
- FTTH, FTTO
