Broad band dispersion slope compensation of dispersion shifted fiber using negative slope fiber

24th European Conference on Optical Communication. ECOC '98 (IEEE Cat. No.98TH8398), 2002
The dispersion of zero and/or non-zero dispersion shifted fiber (DSF) at 1550 nm was compensated to be flat about 30 nm band-range, by connecting with dispersion slope compensating fiber, with negative slope of 20 times larger absolute value than DSF.

Negative slope dispersion compensating fibers

OFC/IOOC . Technical Digest. Optical Fiber Communication Conference, 1999, and the International Conference on Integrated Optics and Optical Fiber Communication, 2003
Two types of DC fibers are presented. The first is an improved high figure of merit (267) negative slope dispersion-compensating fiber intended for DC modules. Also presented is a type II DC fiber intended for field deployment that leads to total broadband dispersion compensation.

Research on dispersion-compensating fibre with negative dispersion slope

Czechoslovak Journal of Physics, 1999
Theory of three-cladding dispersion-compensating fibre (DCF) with negative dispersion slope is analyzed, suggestions of adjusting various parameters in DCF are given, and a novel overclad technology is proposed. At the same time spinning when drawing was applied to lower polarization mode dispersion in DCF, and finally modified chemical vapour ...

Fiber Bragg gratings for pure dispersion-slope compensation

Optics Letters, 2003
Single-fiber Bragg gratings designed to compensate for pure third-order dispersion are demonstrated. The devices are designed by use of a layer-peeling inverse-scattering technique and exhibit dispersion profiles across their reflection bandwidths of -20, +/- 40, and -225 ps/nm2 over bandwidths of 4.5, 6, and 3 nm, respectively.

Compensator for dispersion and dispersion slope using fiber Bragg gratings

SPIE Proceedings, 2006
We propose a novel method of tunable compensation for dispersion and dispersion slope based on a uniform fiber Bragg gratings (FBGs). A specially designed mechanical rotator and a metal beam with a thickness gradient can induce a nonlinear strain gradient along the length of the gratings so as to control the dispersion of the gratings and their ...

Non-zero dispersion shifted fiber with low dispersion slope

Fifth Asia-Pacific Conference on ... and Fourth Optoelectronics and Communications Conference on Communications,, 1999
A new non-zero-dispersion-shifted fiber design is presented. These fibers, with low dispersion slope of 0.03 ps/nm/sup 2/-km and small negative dispersion from 1530 to 1620 nm, are ideal transmission medium for use in broad band DWDM systems.

Hole-assisted lightguide fibers with small negative dispersion and low dispersion slope

Applied Optics, 2008
A nonzero dispersion shifted fiber design based on hole-assisted lightguide fiber is presented. The proposed fiber has low dispersion slope around -0.01 ps/nm(2)-km and small negative dispersion values over the wavelength range from 1530 to 1620 nm. It can be used as a transmission medium for a long-haul dense wavelength-division-multiplexed system.

WDM transmission system using dispersion slope management

SPIE Proceedings, 1998
In wavelength division multiplexing (WDM) transmission systems, it is a problem that the transmission characteristics are degraded due to the fiber nonlinear effects. These nonlinear effects are caused by the pulse collision due to the group velocity difference between different channels.

Modules for chromatic dispersion and dispersion slope management

Optical Fiber Communication Conference and Exhibit, 2002
Dispersion management of high-speed, broadband, long-distance networks calls for continuous full-slope matching of all DWDM channels, as well as low insertion loss, low PMD and low sensitivity to non-linear effects. Dispersion compensation via the fundamental mode meets most requirements, but is inherently accompanied by very small effective areas ...
