Multimode Fiber |
|
|
 |
Because
of its high capacity and reliability, multi-mode optical fiber
coupling laser generally is used for many fields. Because multimode
fiber has a larger core-size, it supports more than one propagation
mode; hence it is limited by modal dispersion. Also, because of
their larger core size, multi-mode fibers have higher numerical
apertures which means they are better at collecting light than
single-mode fibers. Due to the modal dispersion in the fiber,
multimode fiber has higher pulse spreading rates. |
