The polarized phase of the transmitted light can be conserved for a long distance owing to the two stress-applying units in the fiber. Optical signals are transmitted without deteriorating cross-talk values even when aconnector is connected. Features The polarized phase (straight line polarization) of transmitted light can be conserved for a long distance. This cord can be applied to various sensors by taking advantage of the polarization and phase characteristics. We can offer in the form of couplers with a connector to conserve the polarized phase.
