Product description
Huatai HRS-24-H1 product series is a kind of CATV & SAT-IF optical receiver with high-performance and high-index. 7~2400MHz operate bandwidth. Output level Vo=86dBμV ( Pin=-2dBm ), suitable for FTTH, FTTP fiber access network. It is a low power consumption, high performance and excellent cost performance CATV & DBS network ONU(Optical network unit).
This series product adopts high sensitivity receiving tube and 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 48dB and low inter modulation index. If adopting HRS-24-H1, it is only need very low optical power to reach 48dB CNR required by the user.
HRS-24-H1 optical port mode with following three types optional:
HRS-24-H1/NC:RFTV operating wavelength 1260~1620nm.
HRS-24-H1/WF:Build-in channel filter, RFTV operating wavelength 1550nm.
HRS-24-H1/WD:Build-in CWDM, RFTV operating wavelength 1550nm,pass
   wavelength 1310/1490nm, ( Link EPON、GPON ONU ).
