Specialty Optical Fibers Handbook

for mid-infrared (MIR) light transmission and to make praseodymium and

thulium-doped fiber amplifier and sources. ‘‘MIR’’ optical fibers transmit light

between 2 and 5 mm. Specialty optical fibers are often classified and, therefore,

marketed by their optical, environmental, and mechanical specifications.

1.2.2 Tellurite Fiber

Tellurite fibers will also remain a niche market. The application is often

associated with the wideband fiber amplifier, but other alternative or competitive

technology exists. ElectroniCast considers Tellurite optical fibers an R&D fiber.

However, Tellurite optical fibers are considered more controllable in terms of

optical signal ...
