An optical-waveguide cable which is distinguished by a dispersion that avoids non-linearities in conjunction with a relatively low attenuation comprises at least one first section (a), which has fibers of a first type (H) which are designed as high-level fiber, and at least one second section (b), which has fibers of a second type (N) which are designed as low-level fiber, the fibers of the first type (H) being connected to the fibers of the second type (N) at at least one transition point (U) between the first and second sections (a, b), and the fibers of the first type (H) having a larger mode field diameter and a higher dispersion than the fibers of the second type (N). Furthermore, a method for transmitting optical signals is proposed, in which the optical signals to be transmitted are coupled into fibers of the first type (H) of a first section (a) of such an optical-waveguide cable and, after a specific transmission path, are fed into fibers of the second type (N) of a second section (b) of the optical-waveguide cable.

Lightwaveguide cable and process for carrying an optical signal using dispersion management

The invention is directed to an immersion agent that can be used to couple optical waveguides to optical components. The invention is also directed to the use of an immersion agent, a coupling arrangement and a method for coupling optical waveguides to other optical components; for example, an optical chip.

Immersion agent, coupling device and method for coupling an optical waveguide

A strand element for an optical cable which strand element has several light waveguide fibers for transmission of light waves received in a protective casing which surrounds the fibers and has an internal interior diameter which is larger than the exterior diameter of a hypothetical cylinder which surrounds the fibers characterized by each of the fibers being surrounded by a soft elastic material and being stranded with one another, and the space between the stranded optical fibers and the protective casing, which is capable of resistance, being filled with an easily shapeable filling compound which remains very soft and which displays no tendencies towards aging, melting or freezing.

Optical cable with thixotropic filling compound

An optical intermediate amplifier intended for a system of communications transmission by means of light waves through optical wave guides employs an optical amplifier for amplifying the light waves on the laser principle. The amplifier is provided with rectangular cross sectional areas traversed by the light waves which correspond in size with the cross-sectional areas of the core zones of the wave guides with which the amplifier is serially coupled, the rectangular cross sectional areas having heights of 0.1 to 10 .mu.m and widths of 100 to 300 .mu.m.
