Raman EDFA Module

Beogold's Raman amplifier module can be used for optical signal amplification in ultra-long-haul and dense wavelength division multiplexing (DWDM) systems to increase transmission distance. The module uses multi-pump laser multiplexer technology to achieve flat gain, low-noise optical signal amplification across C-band through a combination of different types of pump lasers and fibre type. For laser safety considerations, the module incorporates automatic shut-down mechanism, which automatically turns off the laser output when incidents, such as fibre breakage, line aging occur to ensure personal safety. The module has built-in drive circuitry and logic control circuitry to monitor key information such as pump laser temperature and module temperature in real time. All state parameters and configuration information can be flexibly adjusted and monitored by the upper computer control software. Default module state parameters can be provided according to specific order information and customer requirements. Module, table and rack mounted structures are available for different needs.
