Polarization Maintaining 980 nm Telecommunication Fiber
Nufern’s Polarization Maintaining Telco fibers are designed for today's most advanced networks. Optimized for use at 980 nm, these fibers are used in all PM applications for data and telecom. Nufern has applied its unique manufacturing facility and capabilities to this product area and has established leading optical, mechanical and geometrical tolerances. The bend insensitive versions of our fibers offer lowest bend loss and extinction ratios at small bend diameters enabling our customers to reduce package sizes. Available in either 250 or 400 micron coating diameters and prooftested to 200 kpsi, Nufern's PM fibers will meet the demands of all current and future applications.
≤ - 30.0 dB at 100 m @ 980 nm
Geometrical & Mechanical Specifications
Coating Requirements: UV Curable, Dual Acrylate.
Special Core Dopants: SiO2/GeO2.
The Bend Loss at 980 nm (100 turns as LTBR) is <0.001 dB, by design.
The Bend Radius for 0.05 dB/100 Turns at 980 nm is much less than LTBR, by design.
The Bend Radius for 0.05 dB/100 turns at 1550 nm is 15 mm, by design.
