Photosensitive Single-Mode Fibers

Product catalog summary

Overview: Nufern's photosensitive single-mode fibers are engineered to minimize grating-writing times compared to standard telecommunication fibers, offering cost-effective solutions for creating high-quality, repeatable gratings quickly. These fibers are also designed for easy splicing.

Typical Applications:

Wavelength Division Multiplexing (WDM)
Gain flattening filters
Dispersion compensators
Pump stabilizers

Features & Benefits:

Enhanced photosensitivity for shorter grating writing time
Mode-matched to transmission fibers for low splice loss
Tightly controlled specifications ensuring excellent uniformity
