摘要： Disclosed is a dispersion-compensating (DC) optical fiber 10 that is designed to support the fundamental mode of radiation at 1550 nm. The DC fiber is fabricated from silica glass and has a refractive index profile that includes a core region 51 surrounded by a cladding region 52 having a nominal refractive index n4. The core region includes a central core 511 having a nominal refractive index n1, a “trench” 512 surrounding the central core having a nominal refractive index n2, and a “ridge” 513 surrounding the trench having a nominal refractive index n3. A range of refractive index profiles has been found that provides relative dispersion slopes (RDS) that are greater than 0.012 nm−1 and figures of merit that are greater than 200 ps/(nm·dB). The range is conveniently expressed in terms of index differences and radial dimensions: central core: radius=1.5±0.5 &mgr;m, and 0.015

摘要： Disclosed is a dispersion-compensating (DC) module [740] comprising a first length of DC optical fiber [10] in tandem with a second length of a standard singlemode optical fiber. The DC fiber is fabricated from silica glass and has a refractive index profile that includes a core region [51] surrounded by a cladding region [52] having a nominal refractive index n4. The core region includes a central core [511] having a nominal refractive index n1, a “trench” [512] surrounding the central core having a nominal refractive index n2, and a “ridge” [513] surrounding the trench having a nominal refractive index n3. A range of refractive index profiles has been found that provides relative dispersion slopes (RDS) that are greater than 0.012 nm−1 and figures of merit that are greater than 200 ps/(nm·dB).

摘要： Disclosed is a dispersion-compensating (DC) optical fiber 10 that is designed to support only the fundamental mode of radiation at 1550 nm. The DC fiber is fabricated from silica glass and has a refractive index profile that includes a core region 51 surrounded by a cladding region 52 having a nominal refractive index n4. The core region includes a central core 511 having a nominal refractive index n1, a “trench” 512 surrounding the central core having a nominal refractive index n2, and a “ridge” 513 surrounding the trench having a nominal refractive index n3. A range of refractive index profiles has been found that provides figures of merit that are greater than 300 ps/(nm·dB) and relative dispersion slopes that are greater than 0.01 nm−1. The range is conveniently expressed in terms of index differences and radial dimensions: central core: radius=1.5±0.5 &mgr;m, and 0.015
