Techopedia Explains Fiber Optic Jumper

The majority of fiber optic jumpers have the same type of connector on both ends. Although rare, a fiber optic jumper can be of the hybrid form, meaning it can have different kinds of connectors on each end. Connectors on the end of fiber optic jumper cables can be of various types, including SC, ST, FC, LC, MU, MTRJ or E2000. Fiber optic jumpers can be of two types: single mode (with a yellow cable jacket) and multimode (with an orange cable jacket). These jumpers can be simplex (with one connector on each end) or duplex (with two connectors on each end).
