Description
Springtek DWDM SFP Transceiver exhibits excellent wavelength stability, supporting operation at 100 GHz channel, cost effective module. It is designed for DWDM SONET/ SDH, Gigabit Ethernet and Fiber- Channel applications.
The transceiver consists of two sections: The transmitter section incorporates a colded DFB laser. And the receiver section consists of an APD photodiode integrated with a TIA.Springtek DWDM SFP modules satisfy class I laser safety requirements.
DWDM SFP transceiver provides an enhanced monitoring interface, which allows real-time access to device operating parameters such as transceiver temperature, laser bias current, transmitted optical power, received optical power and transceiver supply voltage, laser temperature and TEC current.
