Pluggable Optical Interfaces and Their Compatibility with Xilinx FPGAs
... Single-mode fiber consists of a single strand of fiber that the data is transmitted across. Multi-mode fiber is composed of multiple strands of fiber bundled together, where light can pass across each strand. In either case, an effect known as dispersion can impact the fidelity of the transmit signa ...
