摘要： A method for producing a glass preform for optical fibers in which fluorine is efficiently incorporated into the preform without incorporation of Fe or Cu. A fine glass particle mass, made primarily of quartz, is converted into transparent glass by heating it in a gas atmosphere containing at least a fluorine-based compound gas and a chlorine-based compound gas. The preferred heating range is 1,100.degree. to 1,400.degree. C.

摘要： A dispersion compensating fiber has a negative chromatic dispersion slope and a value of chromatic dispersion suitable for practical application, and a bending loss thereof with a bending diameter of 40 mm is smaller than 0.01 dB/m at 1.55 .mu.m. A diameter of a core is larger than 3 .mu.m but smaller than 4 .mu.m. A ratio (Da/Db) of the diameter of the core to an outer diameter of a first cladding is between 0.4 and 0.6 both inclusive. A relative refractive index difference of the core to a second cladding, (nc-n2)/n2, is larger than 0.02 but smaller than 0.03. A relative refractive index difference of the first cladding to the second cladding, (n2-n1)/n2, is larger than 0.004 but smaller than 0.01. This dispersion compensating optical fiber has a sufficient negative chromatic dispersion slope at wavelengths (1.55 .mu.m to 1.65 .mu.m both inclusive) around 1.55 .mu.m and a bending loss thereof at the wavelength of 1.55 .mu.m with the bending diameter of 40 mm is smaller than 0.01 dB/m.

摘要： The present invention relates to a package in which an optical waveguide module is mounted, at least having such structure as to reduce influence of expansion or contraction (thermal stress) of a metal housing, caused with a temperature change of the external environment and applied on junction parts between an optical waveguide substrate and members for fixedly supporting tip portions of input and output optical fibers. This package comprises a cavity for housing the whole of the optical waveguide module as covered with a buffer protection material, and a metal housing having through holes for leading the above optical fibers to the outside. Particularly, the optical fibers and the through holes are bonded and secured with a filler having higher airtightness than the buffer protection material and having a lower tensile modulus than a metal material forming the housing.
