1480/1550nm Wavelength Division Multiplexer (WDM)

1480/1550nm Wavelength Division Multiplexer (WDM)
1480/1550nm Wavelength Division
Multiplexer (WDM)
Overview:
1480/1550nm and 1480/1590nm WDM couplers are widely used in EDFA. They combine the 1480nm
pump power and optical signal into the Er-fiber. 1480/1550nm WDM is used for EDFA C-band;
1480/1590nm WDM in EDFA L-band.
Features:
* Low insertion loss
* Low PDL
* High wavelength isolation
* High stability and reliability
Applications:
* EDFA
