摘要:
A mesh (36) is placed around a bundle (32) of fused glass fibers. The bundle is then immersed in a leaching bath (44). The ends of the bundle are protected from the bath fluid by ferrules (34). Some of the glass of the bundle is leached out, so as to provide a flexible fiber bundle.
摘要:
According to the invention, the signal quality on passing through a device for the transmission of optical signals, comprising a waveguide with a doped region, containing a material suitable for the amplification of optical signals may be impaired as little as possible, whereby the doped region has a pre-defined absorption and may have the amplification thereof altered by the injection of pumping light.
