The EM650 laser module combines a DFB laser chip, an ultra-low noise current source and a temperature control unit.
The optical fiber Raman amplifier module is designed to amplify the optical signal of the ultra-long-distance optical transmission system and the dense wavelength division multiplexing (DWDM) optical transmission system to increase the transmission distance. A The module uses multiple pump laser combining technology, through the combination of different types of pump lasers and the matching of fiber types, to achieve flat gain and low noise optical signal amplification in the C-band range. Especially for the safety of Raman amplifiers, the module is designed to automatically pump the laser off function, which can automatically turn off the laser output according to different types of events, such as fiber breakage, line aging, etc., to ensure personal safety.
