980nm pump laser diode protector is a specially designed band-stop filter. This filter is connected to the output of the 980nm pump laser diode. It filters out any possible light from the optical link that may enter the 980nm laser diode and affect its operation or even damage it. Based on the applications, the stop band of the filter is C band (1520~1620nm) for Erbium doped fiber amplifier/laser systems, or at 1064nm (1020~1100nm) for fiber laser systems at 1060nm or 1064nm.
The filter has low insertion loss from 960 to 990nm. Hence it does not affect the 980nm pump laser.


  • Low insertion loss
  • High isolation at stopband
  • High optical power hanlding
  • High stability and reliability


  • Optical fiber amplifiers
  • Optical fiber lasers


Stop band at C band:

Stop band at 1064nm:

Ordering Information:

a: Stopband center wavelength, a=C for C band; a=1064 for 1064nm.
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: SF-980-1064-1-FA
Band stop filter designed to filter out 1064nm or 1550nm ASE power, and protect 980nm pump laser diode, wide stop band, high isolation, low cost
