CATV FTTC FTTB Rfog Outdoor Optical Receiver Node
1. Product Summary
High response PIN photoelectric conversion tube.Optimized circuit design, SMT process production, optimized signal path, make the photoelectric signal transmission more smooth.Specialized RF attenuation chip, with good RF attenuation and equilibrium linear, high accuracy.GaAs amplifier device, power doubler output, with high gain and low distortion.Single Chip Microcomputer (SCM) control equipment working, LCD display
the parameters, convenience and intuitive operation, and stable performance.Excellent AGC performance, when the input optical power range is -9~+2dBm, the output level keep unchanged, CTB and CSO basically unchanged.Reserved data communication interface, can connect with the Ethernet transponder, access to network management system.Return emission can select burst mode to sharply decrease the noise convergence and reduce the forepart receiver number.ONU module optional.
3. Technique Parameter
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 modulated signal at the range of 550MHz~862/1003MHz, the digital modulated 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 8dB
output tilt, measure the C/CTB, C/CSO
and C/N.Backward optical transmit part: Link flatness and NPR
dynamic range are the link indexes which is composed of backward
optical transmitter and backward
optical receiver.
