CATV 1u Four-Way Return Optical Receiver

1. Product SummaryThis optical receiver can automatically set or manually adjust the input signal on/off function (RFOG), greatly curb the overall network noise. Add optical AGC function, keep the output constant when the signal changed in a wide range; and add microcomputer condition monitoring circuit and front panel display screen, support standard Ethernet network management transponder.2. Performance CharacteristicsOptimized circuit design, SMT process production, optimized signal path, make the photoelectric signal transmission more smooth.SCM control working status, LCD displays the parameters, convenience and intuitive operation, and stable performance.Excellent AGC characteristic, keep stable output level in the received optical power range -10~0dBm.Can switch to burst mode, greatly reduced the link aggregation noise; with single way RF shut off function, the localization diagnosis of ingress noise is easy.Support dual power supply hot backup mode and four-way mixed output mode.Reserved data communication interface, can connect with Ethernet transponder, access to network management system.4.
