Sample Spectrum

Transmission spectrum for a sample FBG with center wavelength of 1546.83nm and 90% reflectivity:

Please note: the FBG is made on bare single mode fiber and has no steel tube or any other types of package. Connectors can be spliced on both ends of the fiber Bragg gratings upon request.

Ordering Information:

FBG-S-a-b-e-c-d
a: Center Wavelength in nm, for example a=1550.50 for 1550.50nm.
b: Bandwidth (-3dB) in nm; b=0.2 for 0.2nm, b=0.5 for 0.5nm, etc.
e: Peak Reflectivity; e=0.9 for 90% reflectivity at the center wavelength; e=0.5 for 50%, etc.
c: Fiber Pigtail Type; c=0 for 250 micron bare fiber; c=1 for 0.9mm loose tube pigtail (excluding the grating section).
d: Connector Type, d=FA for FC/APC, d=SU for SC/UPC, d=N for no connectors, etc.

Example: FBG-S-1535-0.3-0.95-0-N
