Product Description

1. Product Summary
This 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 Characteristics

• Optimized 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.
