ANAHEIM, Calif. -- OFC 2002 -- Nufern, an independent provider of application-specific optical fiber, has released its line of metalized optical fibers for use in soldered ferrule packages such as diode lasers, external modulators, and receiver modules. Providing plating-to-fiber adhesion of >3 lbs. and ductility in bending of >1.3%, Nufern metalized pigtails are available with Nufern’s application-specific fibers and many standard telecommunication fibers."This product line is another example of our range of in-house production," said Nufern Vice President of Operations, Dr. Kanishka Tankala. "With the unique plating processes and statistical process controls we have in place, we are able to provide customers with the kind of highly-engineered, repeatable, tight specification, application-specific products they require, even at high volumes."In a separate release:Nufern, an independent provider of application-specific optical fiber, has released four lines of photosensitive fibers — cladding mode offset fibers, cladding mode suppressed fibers, pump locker fibers, and fibers mode-matched to SMF28™.Designed for use in WDM and DWDM applications, Nufern’s Photosensitive Fibers exhibit uniform and controlled photosensitivity to conventional UV radiation techniques and are available in a wide range of photosensitivities. These photosensitive fibers provide a cost-savings for grating-writing because customers can write repeatable, quality gratings in a short time."Photosensitive is where it all started for us," said Nufern CTO, Dr. Adrian Carter. "Since 1998, we’ve been a leading independent manufacturer. Now we can offer customers four photosensitive product lines off-the-shelf, as well as custom-made photosensitive fibers."In a separate release:Nufern, an independent provider of application-specific optical fiber, has released the first product in its new line of high-performance Planar Waveguide fibers. Designed for specific mode-matching requirements in adiabatic splice diffusion between high NA Planar Waveguide chip technology and low NA telecommunications and component fibers, Nufern’s Planar Waveguide Fiber provides uniform transition, better performance, and lower insertion losses than the traditional lensing and anti-reflection coating methods."This is the first in a series of fibers that will give the Planar Waveguide industry improved interface with telecommunications and component fibers," said Nufern CTO, Dr. Adrian Carter. "Rather than a ‘band aid’ approach using lenses and coatings, this product allows for more efficient transition between fiber and chip optics."In a separate release:Nufern, an independent provider of application-specific optical fiber, has released its Polarization Maintaining PM14XX-HP (High- Performance) Fiber. Providing identical optical performance as the current standard with tighter mechanical tolerances and core/clad concentricity, Nufern’s PM14XX-HP is proof-tested at ≥ 200 kpsi and is available in standard or specialty lengths.According to Nufern Vice President of Operations, Dr. Kanishka Tankala, "We’ve captured all the optical performance characteristics and, through our statistical process controls, improved its geometrical and optical tolerances. The fact that we accomplished this in the short amount of time since the Panda™ fiber patent expired speaks well of our plant-processes and the motivation of our people."In a separate release:Nufern, an independent provider of application-specific optical fiber, has released its family of select cut-off single-mode fibers in operating wavelengths including 460 nm, 630 nm, 780 nm, 980 nm, 1060 nm and higher.Designed for use in telecommunications, visible-wavelength, RGB and short-wavelength applications, these high-performance fibers offer exceptional uniformity and core/clad concentricity specifications. In addition, these fibers offer tight second mode cut-off tolerances, tighter bend radius applications in miniaturized fiber optic packages, and are available in 80 µm and 125 µm form factors."This line addresses the breadth of the market," said Nufern President and CEO, Martin Seifert. "From deep blue visible, through video RGB, to infrared telecom, we are delivering what our customers need today — with better optical and mechanical tolerances."In a separate release:Nufern, an independent provider of application-specific optical fiber, has released its line of ultra-high-numerical-aperture fibers. These fibers are uniquely designed to meet stringent splice requirements for mode-matching amplifiers and laser components that use Fluoride fibers. They also fill other specific mode-matching applications such as adiabatic splice diffusion and act as combined attachments to standard telecommunication fibers.Nufern’s Ultra-High NA Fibers have numerical apertures between 0.25 and 0.35, depending on customer specifications, with standard second-mode cut-offs in the range of 800 - 1100 nm with tight tolerances. They are proof-tested at 100 kpsi, as a standard, with higher proof-test levels available.Nufern CTO, Dr. Adrian Carter said, "In the future, 80–90 percent of Planar Waveguide (PWG) and other active and passive components could utilize this type of fiber. This is another example of our filling a need in the marketplace for a secure supply of commercial-grade, application-specific fiber."NufernFor more information on OFC 2002, please visit: www.nottheofc.com
