New hydrogen aging loss mechanism in the 1400 nm window

K.H. Chang; David Kalish; Michael L. Pearsall

A new type of hydrogen aging loss increase of up to 0.21 dB/km at the 1385 nn OH peak can arise in some fibers when exposed to 0.01 atmospheres of hydrogen for less than 4 days at room-temperature.


optical fiber communication conference | 1985

Dispersion-shifted depressed-clad triangular-profile single-mode fiber

Hen-Tai Shang; Terrence Albert Lenahan; Paul F. Glodis; David Kalish

Conventional dual-window single-mode fiber has minimum attenuation in its 1.55-μm window. Because of high chromatic dispersion at this wavelength, its full capacity can be utilized only in a system using unconventional single-frequency lasers. Alternatively, a high-bit-rate system with repeater spacing over 100 km is possible with conventional multimode lasers when dispersion-shifted single-mode fiber is used.
