Abstract: A wire cover includes an inner cover member covering a bent section of an electric wire from an inner peripheral side and an outer cover member covering the bent section from an outer peripheral side. One end portion of the wire cover sandwiches the electric wire along a first direction. The other end portion of the wire cover sandwiches the electric wire along a second direction. The inner cover member and the outer cover member move relative to each other along the first direction. When observed from a third direction intersecting a plane that includes the first direction and the second direction, a first attachment portion and a second attachment portion are positioned outward of the surface of the inner cover body on the innermost side of the bent section or inward of the surface of the outer cover body on the outermost side of the bent section.

Abstract: An optical communication device includes a conversion unit that receives an optical signal transmitted from a first optical communication device and converts the optical signal into a digital electric signal based on a clock signal, a clock switching unit that switches an oscillator generating the clock signal, and an operation mode control unit that detects an operation mode of the first optical communication device in the digital electric signal and commands the clock switching unit to perform switching from the oscillator generating the clock signal to an oscillator generating a clock signal at a frequency based on the operation mode of the first optical communication device.
