PM Coupler

980/1550nm & 1480/1550nm Fused WDM

 

980/1550nm and 1480/1550nm WDM are widely used in EDFA. They combine the pump power and optical signal into the Er-fiber. 980/1550nm WDM is used for EDFA C-band, and the 980/1590nm WDM is used for EDFA L-band. The normal WDM were built of Corning HI1060flex or OFS BF05635-02 fiber.

The mixed fiber 980/1550nm WDM uses SMF-28 standard fiber as coupler’s 1550nm signal port, while the 980nm pump port and the common port use Corning HI1060flex or OFS BF05635-02 980nm fiber.
 
The products are Telcordia GR-1221/1209-CORE qualified, and RoHS compliant.
