Weatherproof Field 1003Mhz CATV Optical Node 1550nm For NGB Network

SR1104 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.

PIN photoelectric translating tube with high response. Line optimal design and SMT production process are useful for optimized signal channel and fluid optical signal transmission. RF attenuation, balanced linear and precision of professional RF attenuation chip are good. Power-double output of GaAs amplifier has high gain, low distortion and small heat dissipating capacity. The complete machine is controlled by single-chip. The parameters will be displayed by digital display. The operation is convenient and clear. The performance is stable. AGC characteristics are good. Output level is unchanged and CTB,CSO is essentially the same when optical power input is changed(-9～+2dBm). Connect to the network management responder, access the network management system  by reserving data  communication  interface.
