950~2600MHz Satellite L-Band PIN Optical Receiver
Softel SRS-2600CSP product series is a kind of CATV & SAT-IF optical receiver with high-performance and high-index. 7~2400MHz operate bandwidth. Output level Vo=86dBμ V ( 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 SRS-2600FP, it is only need very low optical power to reach 48dB CNR required by the user.
SRS-2600FP optical port mode with following three types optional:
SRS-2600FP/NC: RFTV operating wavelength 1260~1620nm.
SRS-2600FP/WF: Build-in channel filter, RFTV operating wavelength 1550nm.
SRS-2600FP/WD: Build-in CWDM, RFTV operating wavelength 1550nm, pass
Wavelength 1310/1490nm, ( Link EPON, GPON ONU ).
Extra-low noise ( 3.8% modulate, -8dBm receive, CNR≥ 48dB )
In high operating wavelength 47~2400MHz, adopting CATV & SAT-IF signal transmitting
Analog TV, Digital TV, SAT-TV, all have excellent features:
Analog TV: ( 59CH PAL-D, 3.8% modulation )
Pin=-10dBm, CNR≥ 44dB
Pin=0dBm, CTB ≤ -65dB, CSO ≤ -65dB
Digital TV: ( The original signal MER=38.6dBm, BER<1.0E-9 )
Pin=-14dBm, MER≥ 33dB ( MER deterioration5dB )
Pin=-19dBm, BER<1.0E-9
SAT-TV: ( The original signal =64% )
Pin=-15dBm, signal quality>38%
Large dynamic range of received optical power, high receiving sensitivity:
Analog TV: +2dBm~ -10dBm
Digital TV: +2dBm~ -19dBm
SAT-TV: +2dBm~ -15dBm
Extra-low inter modulation indicators
High output level ( Pin=-2dBm, Vo=86dBμ V )
In range of 47~2400MHz, all have good flatness
Metal shell, supply safeguards to opt electrical sensing device
Low power consumption, high cost performance
