During that time Paul also wrote her latest book, Tough Broad: From Boogie Boarding to Wing Walking, How Outdoor Adventure Improves Our Lives as We Age. Paul looks at the latest research and social science on aging, and embarks on adventures that range from scuba diving with an octagenarean, to hiking with a 93-year-old, to birdwatching.
Hard-clad silica (HCS) or polymer-clad fiber (PCF) is an optical fiber with a core of silica glass (diameter: 200 μm) and an optical cladding made of special plastic (diameter: 230 μm). In contrast to all-silica fiber , the core and cladding can be separated from each other.
Non-zero dispersion-shifted fiber (NZDSF), specified in ITU-T G.655, is a type of single-mode optical fiber which was designed to overcome the problems of dispersion-shifted fiber. NZDSF is available in two primary flavours: NZD+ and NZD-, which differ in their zero-dispersion wavelengths . [ 1 ]
Optical fiber manufacturers have greatly refined their manufacturing process since that standard was issued and cables can be made that support 10 GbE up to 400 meters. Laser optimized multi-mode fiber (LOMMF) is designed for use with 850 nm VCSELs. Older FDDI grade, OM1, and OM2 fiber can be used for 10 Gigabit Ethernet through 10GBASE-LRM.

Dispersion-shifted fiber (DSF) is a type of optical fiber made to optimize both low dispersion and low attenuation. Dispersion Shifted Fiber is a type of single-mode optical fiber with a core-clad index profile tailored to shift the zero-dispersion wavelength from the natural 1300 nm in silica -glass fibers to the minimum-loss window at 1550 nm.
Different criteria for "broad" have been applied in different contexts and at different times. Its origin is in physics, acoustics, and radio systems engineering, where it had been used with a meaning similar to "wideband", [4] [5] or in the context of audio noise reduction systems, where it indicated a single-band rather than a multiple-audio-band system design of the compander.
