DIGITAL DIAGNOSTIC FUNCTIONS
The Cisco SFP optics for POS and ATM applications allow real-time access, through the digital diagnostic monitoring interface, to a set of
transceiver parameters such as optical output power, optical input power, temperature, laser bias current, and transceiver supply voltage.
The ability to read these parameters in real time greatly enhances the installation, activation, and troubleshooting of these SFP optics.
