Description
Technical field
The present invention relates to technical field of optical fiber, particularly relate to a kind of optical fiber joint end head.
Background technology
In prior art, mostly lay the single-mode fiber of 1.3 μm standards, in order to make to have used 1.3
μm fibre system uses WDM/EDFA technology, is necessary for transferring the operation wavelength of optical fiber to 1.55 from 1.3 μm
μm, and standard fiber is not zero in the dispersion of 1.55 mum wavelengths, but positive (17-20) ps/ (nm
Km), and there is positive chromatic dispersion gradient, so the color of negative dispersion must be had adjunction in these optical fiber
Dissipate compensated optical fiber, carry out dispersion compensation, to ensure that the total dispersion of whole piece fibre circuit is approximately zero, thus real
The now communication of high speed, Large Copacity, distance.
How both single-mode fiber and Dispersion compensating fiber are linked together, and effectively reduce signal damage
Lose so that signal can high efficiency pass through, and is problems of the prior art.
Summary of the invention
