Photosensitive Single-Mode Low-NA Fiber0 pages

Photosensitive Single-Mode Fibers
Nufern photosensitive fibers are designed to reduce grating-writing times associated with industry-standard
telecommunication fiber and can be easily spliced. These photosensitive fibers provide cost-savings for grating-writing
because customers can write highly repeatable, quality gratings in a short time.
Typical Applications
Features & Benefits
• WDM
• Enhanced photosensitivity — Shorter grating writing time
• Gain flattening filters
• Mode-matched to transmission fibers — Low splice loss
• Dispersion compensators
• Tightly controlled specifications — Excellent uniformity
• Pump stabilizers
