Embodiment Construction

[0031] Aspects of the invention relate to dispersion compensating modules (DCMs) for use in coherent detection transmission systems, and to dispersion compensating fibers (DCFs) suitable for use in the described dispersion compensating modules.

[0032] Using the DCF of the present invention with an effective area increase of 4.5 times compared to other single-mode high FOM DCFs, a DCM with an FOM improvement of nearly 5 times compared to other known modules is described. Specifically, the enabling technology (enabling technology) is included in the LP 02 Or a few-mode fiber working at a higher mode. Fibers that support multiple modes are often associated with noise formed through multipath interference (MPI) due to the different propagation constants of the individual modes. However, a low MPI of -37dB is obtained even though the fiber of the present invention is not single-mode and a mode converter may be required in the modular system.

Abstract

A dispersion-compensating system and a dispersion-compensating fiber have an improved figure of merit and effective area. The dispersion-compensating system comprises a bulk dispersion-compensating module for providing optical-domain bulk dispersion compensation for an optical signal transmission. Additionally, the system may further comprise residual dispersion compensation, which can be performed in the electrical domain following coherent detection of both amplitude and phase of an optical signal. The dispersion-compensating fiber comprises an up-doped core region, a down-doped trench, an up-doped ring, and an outer cladding, and is configured to have a high figure of merit (FOM).

Description

[0001] Cross References to Related Applications [0002] This application claims priority to the following U.S. Provisional Patent Applications owned by the assignee of this application: [0003] U.S. Provisional Application Serial No. 61 / 379,739 filed September 3, 2010 technical field [0004] The present invention relates generally to fiber optic devices and related methods, and more particularly to improved dispersion compensation systems and dispersion compensating optical fibers having improved figure of merit and effective area. Background technique [0005] Coherent detection followed by digital signal processing in the electrical domain is currently being investigated as a viable technique for transmission systems with increased transmission rates. When both optical amplitude and phase are detected, linear impairments such as chromatic dispersion and polarization mode dispersion (PMD) can be fully compensated in the electrical domain. This method eliminates the nee...
