Dispersion compensation in 1310 nm-optimised SMFs using optical equaliser fibre, EDFAs and 1310/1550 nm WDM

Design optimization of dispersion compensating fibers and their packaging techniques

“…The total accumulated dispersion to cancel out by the DCFM is determined in advance, so the figure of merit (FOM) defined by Eq. (2) has been introduced to express the excellence of the DCF in terms of the attenuation. where D and α represent the dispersion and the attenuation of the DCF.…”

“…Dispersion compensating fiber (DCF) was proposed to equalize the pulse distortion in 1980 [1]. In the early 1990s, numerous DCFs [2][3][4][5][6] were proposed and developed for commercial use. They were initially developed to upgrade the existing systems using 1.3 μm standard single-mode fibers (SSMFs) to higher bit-rate systems [7,8] or long distance transmission [9] in the 1.55-μm windows.…”

Erbium-Doped Dispersion-Compensating Fiber for Simultaneous Compensation of Loss and Dispersion

“…Such DCF can be designed to have a very large negative dispersion coefficient at 1.55 m so as to optically compensate the positive dispersion accumulated in a w x long fiber link by inserting a short section of DCF 6 . Following this logic, system experiments in which dispersion and loss are compensated by using DCF followed by w x EDFA or vice versa have been reported 5,7 .…”

Research of Dispersion Compensation Amount of Chirped FBG on 10 Gbit/s System

“…The solution of this problem is through dispersion compensation [1]· There are many solutions, including dispersion supported-transmission [2], dispersion compensation fibers (DCF) [3], prechirping laser pulse [4], spectrum inversion [5] and chirped fiber Bragg gratings (chirped FBG) [6][7]. At present, there are two significant barriers to achieve high-speed and long-distance transmission.…”
