A method of knitting an intarsia pattern fabric that can prevent occurrence of a yarn catching even when a tubular knitted fabric with an intarsia pattern and the like is knitted by using a four-bed flat knitting machine and also can eliminate the need of a split knitting to provide improved productivity. An actuating element can be displaced along a first axis and releases, in an actuation position, a swivel path for a control unit arranged to swivel about a second axis. By utilizing an outer jacket material having a reduced coefficient of thermal expansion, the need for rigid strength members within the outer jacket is eliminated, thereby providing a fiber optic cable having a reduced size and weight. Electro-optic devices described herein contain one or more of the described electron acceptors, electron donors, conjugated bridges, or chromophores.
