摘要： A chromatic dispersion compensating and dispersion slope compensating optical fiber comprises a central core having an index difference Δn1 with an outer optical cladding, a first buried inner cladding having an index difference Δn2 with the outer cladding, a ring having an index difference Δn3 with the outer cladding and a second buried inner cladding having an index difference Δn4 with the outer cladding. The index difference between the first buried inner cladding and the outer cladding Δn2 is less than or equal to −13.5.10−3 and the index difference between the second buried inner cladding and the outer cladding Δn4 is less than or equal to −3.10−3. The fiber has, for a wavelength of 1550 nm, a chromatic dispersion less than or equal to −50 ps/nm/km and a ratio of the chromatic dispersion over the chromatic dispersion slope DOS less than or equal to 70 nm. The second deeply buried inner cladding allows obtaining a low DOS value whilst maintaining acceptable optical characteristics.

摘要： Disclosed is a chromatic dispersion compensating optical fiber comprising a central core, an intermediate cladding having a width (r2−r1) of 2.0 microns or greater, and a depressed inner cladding having a refractive index difference Dn3 with the external optical cladding of −3.0×10−3 or lower. At a wavelength of 1550 nm, the optical fiber exhibits a positive chromatic dispersion of 21 ps/nm·km or higher and a ratio of mode radius to intermediate cladding radius of (W02/r2) of 0.7 or less. The present optical fiber has a good figure of merit value and limited bending and microbending losses. The optical fiber can be rolled up in a housing of reduced size in a chromatic dispersion compensating optical module having limited insertion losses and reduced polarization mode dispersion
