Digital Optical Monitoring
Transceivers offer the ability to monitor important module parameters during operation. The temperature,
supply voltage, laser bias current, optical transmitter power and receiver optical power parameters are
continuously monitored for getting information about the module’s current status. All data is calibrated
internally; there is no need for external post processing.
Regulatory Compliance
The J4858C modules are designed to meet international requirements and standards in terms of product
safety. The modules optical output power meets Class 1 requirements for laser safety.
