Optical fiber switching module and optical fiber bypass equipment

An optical fiber switching module comprises a shell, at least two first collimators, at least two second collimators, a relay and a plurality of prisms. The shell is provided with a containing space, a first side wall and a second side wall, the first collimator is located on the first side wall. Each of the first collimators is configured to connect an even number of first optical fibers. The second collimator is located on the second side wall. Each of the second collimators is configured to connect an even number of second optical fibers. The second collimators are respectively aligned with the first collimators. The relay is located in the containing space and provided with a rotating support. The prisms are located on the rotating support, and the prisms are located between the first collimator and the second collimator. The rotating bracket is configured such that at least one prism is located on a light transmission path of a portion of the first optical fiber and a portion of the second optical fiber.
