1000Base WDM Single Mode SFP Modules (Upto 10 Km )

 

Product Overview 
Wirewerks small form factor pluggable (SFP) multimode supports Gigabit Ethernet over multimode cables at distances up to 10 km. It is fully compliant to IEEE 802.3z standard for Gigabit Ethernet. It is a cost effective method of providing changeable interfaces to switches and media converters with universal SFP socket. Digital diagnostics monitoring (DDM) functions, also known as digital optical monitoring (DOM), specified in industry standard SFF-8472, is also available as an option. This feature gives the end user the ability to monitor real time parameters of the SFP such as optical output power, optical input power, temperature, laser bias current, and transceiver supply voltage.
