“…The optical fibers have positive dispersion in a C-band operated at a wavelength of 1550 nm and has about 18 ps/(nm.km) dispersion. Whenever the signal transmit through a long distance, the accumulated positive dispersion become big which reduces the signal to noise ratio and increase in bit error rate [11][12][13][14][15]. In order to compensate this DCF is designed which have a negative dispersion in the range of -70 to -90 ps/(nm.km).…”

In this paper, we employed a Dense Wavelength division multiplexing (DWDM) system in which 96 channel optical network is designed, simulated and then analyzed for long haul distance using Dispersion compensation fiber(DCF) and Fiber Bragg Grating(FBG) technique. Symmetric compensation technique is used for DCF and post compensation technique is used for FBG. The simulation result such as Bit error rate (BER) and Quality factor indicate that DCF is better as compared to FBG.

“…After a long transmission distance, the accumulated positive dispersion becomes big, which results in the reduction of the signal to noise ratio (SNR), an increase in bit error rate, and deterioration in the system performance. Therefore, we must design a kind of DCF that can compensate for the accumulated positive dispersion, which has negative dispersion and a negative dispersion slope in the operation wavelength range [11][12][13][14][15][16].…”

Dispersion compensation was originally proposed to equalize pulse distortion. With the development of wavelength division multiplexing (WDM) techniques for large capacity optical communication systems, dispersion compensation technologies have been applied into the field. Fiber-based dispersion compensation is an attractive technology for upgrading WDM communication systems because of its dispersion characteristics and good compatibility with transmission optical fibers. Dispersion compensation fibers and the modules are promising technologies, so they have been receiving more and more attention in recent years.In this work, high performance dispersion compensation fiber modules (DCFMs) were developed and applied for the 40 Giga bit-rate systems. First, the design optimization of the dispersion optical fibers was carried out. In theory, the better the refractive index profile is, the larger the negative dispersion we could obtain and the higher the figure of merit (FOM) for the dispersion optical fiber is. Then we manufactured the fiber by using the plasma chemical vapor deposition (PCVD) process of independent intellectual property rights, and a high performance dispersion optical fiber was fabricated. Dispersion compensation fiber modules are made with the dispersion compensating fibers (DCFs) and pigtail fibers at both ends of the DCFs to connect with the transmission fibers. The DCFMs present the following superior characteristics: low insertion loss (IL), low polarization mode dispersion, good matched dispersion for transmission fibers, low nonlinearity, and good stability for environmental variation.The DCFMs have the functions of dispersion compensation and slope compensation in the wavelength range of 1525 to 1625 nm. The experiments showed that the dispersion compensation modules (DCMs) met the requirements of the GR-1221-CORE, GR-2854-CORE, and GR-63-CORE standards. The residual dispersions of the G.652 transmission lines compensated for by the DCM in the C-band are less than 3.0 ps/nm, and the dispersion slopes are also compensated for by 100%. With the DCFMs, the 8Â80 km unidirectional transmission experiments in the 48-channel 40 Gbps WDM communication system was successfully made, and the results showed that the channel cost was smaller than 1.20 dB, without any bit error.

“…In order to have a large negative dispersion or low optical nonlinearity, the DCFs based on the higher-order mode like LP 11 or LP 02 were also proposed and developed [17][18][19]. The DCFs having an extremely large negative dispersion or DCFs compensating for the loss as well as the dispersion of the transmission fibers simultaneously were also proposed and demonstrated [20,21].…”

Design optimization of dispersion compensating fibers (DCFs) based on the fundamental mode is described considering the packaging technique. Optical performances of the DCF modules are mainly limited by the macro-, micro-bending loss and the polarization mode dispersion that strongly depend on the module structure. Two types of DCF modules are demonstrated as examples. Bobbin-less module structure that mitigates the bending limit is also described.
