A new type of optical switch, which is suitable for application to data paths with a loop bus-line configuration, is described. The switching action is obtained by moving a fiber directly. The insertion loss in the bypass mode is as low as 0.82 dB. R

The loss in a low-loss multimode optical fiber consists of Rayleigh scattering loss and microbending loss. These losses depend on the structural parameters of the fiber. On the other hand, the coupling optical power from optical source into fiber and

Additional loss in a W-type fiber induced by periodic bends is investigated experimentally in comparison with the corresponding singly clad (SCp and SCq) fibers. When the bending amplitude is small, the additional loss of the W-type fiber is almost e
