Design of Dispersion Flattened and Compensating Fibers for Dispersion-Managed Optical Communications Systems

Single mode optical fibers having minimum non-zero dispersion over the spectral windows of 1300 and 1550 nm region are essential for the multi-channel operation of dense wavelength multiplexed systems and minimizing the nonlinear four wave mixing effects This paper demonstrates that nonzero dispersion flattening of the dispersion factor extends over a wavelength range of more than 350 nm is ach...

Inverse Design of Dispersion Compensating Optical Fibres Using Topology Optimization

Dispersion Compensating Fibers

In this paper we briefly review the work on dispersion compensating fibers (DCFs) in the last few years. Starting with the basic principle behind DCF, its need for upgrading the 1310 nm optical fiber links is discussed. The experimental and theoretical results of some researchers have been cited. The latest trend in optical communication has been to use dense wavelength division multiplexed (DW...

Dispersion Compensating Fiber Modules for Dispersion-Shifted Fiber

A dispersion-shifted fiber (DSF) is designed to have its zero dispersion wavelength in 1.55μm wavelength range. Since the dispersion of DSF is close to zero in the C-band, conditions for dense wavelength division multiplexing (DWDM) transmission using DSF are limited due to four wave mixing (FWM). In the L-band, however, the DSF has some dispersion values, so that the DWDM transmission using DS...

Optimal packaging of dispersion-compensating fibers for matched nonlinear compensation and reduced optical noise.

A method of packaging dispersion-compensating fibers (DCFs) is discussed that achieves optimal nonlinearity compensation and a good signal-to-noise ratio simultaneously. An optimally packaged dispersion-compensating module (DCM) may consist of portions of DCFs with higher and lower loss coefficients. Such optimized DCMs may be paired with transmission fibers to form scaled translation-symmetric...
