Is an optical bridge a switch and how do I connect it

An optical switch is a multi-port network bridge, which connects multiple optic fibers to each other and controls data packets routing between inputs and outputs. They're a core component in fiber-optic networks, where data travels as pulses of light through glass fibers. Every time that light needs to change direction or jump. Optical switching is the process of controlling the destination of individual optical information signals.
