SFP Optical Transceiver

Small Form-Factor Pluggable (SFP) Fiber Optical Interface converter is
hot-pluggable inputoutput device that plugs into a slot, linking the port with the network
SFP’s are used and interchanged on wide variety of telecommunication and data communication applications as SONET, Gigabit Ethernet, Fiber Channel and other standards.
DDM (Digital Diagnostics Monitoring) Modules with DDM capability assist network administrators to monitor parameters of the SFP such as optical output power, optical input power, temperature, laser bias current and transceiver supply voltage, in real time.
