Detail Specification for Class IVa Dispersion-Unshifted Single-Mode Optical Fibers with Low Water Peak
| Published By | Publication Date | Number of Pages |
| TIA | 2000 | 30 |
This Detail Specification applies to a Class IVa dispersion-unshifted
single-mode optical fiber
that has low attenuation at wavelengths near the water peak (typically
near 1383 nm). Class IVa
single-mode fiber has a nominal zero-dispersion wavelength in the 1310
nm transmission window. The
fiber is commonly referred to as a dispersion-unshifted (or
non-shifted) fiber, and its dispersion
characteristic is approximated by a differentiated Sellmeier equation
(see 4.4.4 of the Sectional
Specification). This Detail Specification applies to a sub-category of
a Class IVa fiber that is
termed "Low Water Peak" fiber. These fibers are characterized by
having a low, environmentally
stable attenuation coefficient in the vicinity of 1383 nm –
traditionally referred to as the "water
peak."
