OPTEC Wkładka SFP28 WDM SM LC 20KM TX1270 DDM

Transceivers SFP28 25G are modules with the form factor (dimensions) of SFP+ modules, but with electronic components adapted for transmitting at speeds of 25 Gb/s. Thanks to this innovative approach, there is no need to replace the passive infrastructure. Additionally, SFP28 Transceivers are backward compatible with SFP+ ports: they can be used in SFP+ ports, albeit at a speed adjusted accordingly to the port. It's worth noting that this works both ways - switches designed for 25 Gb/s technology and equipped with SFP28/SFP+ ports allow the use of SFP+ modules in SFP28 ports after adjusting the speed in the device settings.

Compatibility also extends to PCC (passive copper cable) and ACC (active copper cable).

The DDM function (Digital Diagnostic Monitor), compatible with Cisco DOM (Digital Optical Monitoring), enables monitoring of key module operating parameters such as optical signal transmit power, optical signal receive power, operating temperature, supply voltage, and laser current. Utilizing DDM helps prevent failures and speeds up troubleshooting of optical networks. Monitoring of operating parameters is only possible with devices implementing the digital diagnostic readout function.
