InfiniBand cable
InfiniBand cables are used to connect MATE copper ports, which use InfiniBand 4X connectors.

Optical fiber
CAUTION:
Use the same types of transceiver modules, pigtail cords, patch cords, and fiber cables. If you use
single-mode optical fibers, the transceiver modules, pigtail cords, patch cords, and fiber cables must be
single-mode.
Optical fiber
Optical fibers are widely used in fiber-optic communications, which are advantageous for long-distance
communications.
Optical fibers can be classified into the following types:
• Single mode fiber—It has a core size of 10 μm or smaller, and has a lower modal dispersion. It
carries only a single ray of light. It is mostly used for communication over longer distances.
• Multi-mode fiber—It has a core size of 50 μm or 62.5 μm or higher, and has a higher modal
dispersion than single-mode optical fiber. It is mostly used for communication over shorter
distances.
