Singlemode Fiber, Highly Photosensitive, FBGs, 1310/1500 nm, 125 µm Clad

The F-SBG-13/15 very Highly Photosensitive Fiber is co-doped with Boron and germanium and is intrinsically photosensitive. This fiber has been designed to match the MFD characteristics of typical, dual-wavelength, 1310nm and 1550nm telecommunications fiber, making it ideal for the fabrication of add-drop multiplexers or Erbium Doped Fiber Amplifier (EDFA) Gain-Flattening Filters (GFFs). With this 1310/1550 nm fiber, a 1 nm wide, 47 dB deep 15 mm long transmission grating can be written in these fibers within a few minutes by a pulsed Excimer Laser (10 Hz, 0.5 J/cm2, 248 nm). Standard pricing is per meter.
