Single-mode fiber can only transmit in one direction

Single-mode fiber can be either simplex or duplex. Simplex fiber optic cable uses only a single fiber strand for one-way transmission, while duplex fiber optic cable uses a pair of fibers for bi-direc...

Is fiber optical signal ouput one-way directional ?

Why can fiber optic cables only transmit in one direction? Fiber optic cables rely on optical-to-electrical conversion and are inherently unidirectional—from a laser transmitter to a light receiver.
