SFP+ OPTEC, 10G, SM LC, 14dB DFB/PIN (40km), TX1310, DDM (SFP-10GBASE-ER)

DDM - Digital Diagnostic Monitor (compatible  z Cisco DOM – Digital Optical Monitoring).

This feature allows you to track key parameters of the module such as the power of the optical signal transmission, the optical power of the received signal, operating temperature, supply voltage, current of the laser. Using DDM can prevent crashing and speed up the diagnostics of network problems optical. Monitoring of operating parameters ensure only devices with a built-in function for reading and diagnosis of digital technologies.
