    Filter Based WDM Couplers - 980/C+L, 1480/C+L

    Model WDM-F
    Price:   US$125.00
    Available Options:
    Center Wavelength:
    Connector Type:
    Pigtail Type:

These two filter-based WDM couplers combine or separate 980nm or 1480nm with C+L band (1520~1600nm). Using these WDMs, wideband Erbium doped fiber amplifiers can be constructured. The WDMs combines the pump laser from 980nm diode or 1480nm diode. Its signal band covers a wide range of wavelengths for both C and L bands. Hence, wide band amplification can be achieved.


  • Wide passing bands and reflection bands
  • High isolation
  • Low insertion loss
  • High stability and reliability


  • Optical fiber amplifiers
  • Optical WDM networks
  • Optical sensor systems


Ordering Information:

a: ID for the pump laser wavelength, a=9 for 950~1010nm, a=14 for 1480nm.
b: ID for the signal wavelength, b=CL for C+L bands.
c: Pigtail Type, c=0 for 250 micron bare fiber pigtail, c=1 for 900 micron loose tube pigtail, etc.
d: Connector Type, d=FA for FC/APC, d=SU for SC/UPC, d=N for no connectors, etc.

Example: WDM-F-9CL-1-SU or WDM-F-14CL-1-N
