Nufern releases new fibers for couplers and FBGs

APRIL 4, 2007 -- Nufern announced the expansion of its NuCOMM line of specialty telecom fibers at OFC/NFOEC last week.

CMS-HP is a photosensitive singlemode fiber designed for the production of complex fiber Bragg grating (FBG) structures, such as those with high channel count, in which cladding mode suppression is a fundamental requirement.

"This fiber sets a new standard for photosensitive telecom fibers," says Dr. Adrian Carter, CTO at Nufern, "with its excellent cladding mode suppression, high intrinsic photosensitivity, and low birefringence."

Optimized for low polarization mode dispersion (PMD), the fiber enables the production of devices, such as dispersion compensating modules, with low polarization-dependent loss (PDL).

A new coupler fiber, 980C-HP, is designed to achieve extremely low bend loss and splice loss, making it ideal for couplers of all sorts and other ultra-compact components requiring small bend radii. In addition to its bending and splicing performance, the fiber's tight second mode cutoff tolerance and high tensile strength allow coupler manufacturers to achieve improved production yields and reduced manufacturing costs, Nufern asserts.
