Dispersion-compensating module |
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).
