SNMP CWDM FTTB CATV Optical Node GaAs Chip RoSH For RF Signal , 6dB ~ 9dB

SR1102 outdoor optical receiver is our latest 1GHz dual-way switch optical receiver. With wide range receiving optical power, high output level, low power consumption. It is the ideal equipment to build the high-performance NGB network.
Forward optical receive part: with 10km standard optical fiber, passive optical attenuator and standard optical transmitter composed the testing link. Set 59 PAL-D analog TV channel signal at range of 45/87MHz～550MHz under the specified link loss. Transmit digital modulation signal at range of 550MHz～862/1003MHz, the digital modulation signal level (in 8 MHz bandwidth) is 10dB lower than analog signal carrier level. When the input optical power of optical receiver is -1dBm, the RF output level is 108dBμV, with 9dB output tilt, measure the C/CTB, C/CSO and C/N.
Note: When the rated output level is the system full configuration and the receiving optical power is -1dBm, equipment meets the maximum output level of link index. When the system configuration reduce (that is, actual transmission channels reduce), the output level of equipment will be increased.
Friendly Notice: Suggest you setting the RF signal to 6~9dB tilt output in the practical engineering application to improve the nonlinear index (under the node) of the cable system.
 
 
 

Adopt advanced optical AGC technique, optical AGC control range: +2dBm ～ -9/-8/-7dBm adjustable; Two-way optical signal received, back up each other, arbitrarily set the auto-switching conditions and can also be set to manual switch; Downlink working frequency extended to 1GHz, RF amplifier part adopts the high performance low power consumption GaAs chip, the highest output level up to 116dBuv; EQ and ATT both use the professional electric control circuit, makes the control more accurate, operation more convenient; Built-in the standard II class network management responder, support remote network management (optional); With compact structure, convenient installation, it is the first choice equipment of FTTB CATV network; Built-in high reliability low power consumption power supply;
