Which cable is used for undersea communication?
Explanation: Modern submarine cables use fiber-optic technology. Lasers on one end fire at extremely rapid rates down thin glass fibers to receptors at the other end of the cable. These glass fibers are wrapped in layers of plastic (and sometimes steel wire) for protection.
Which cable mode is preferred for undersea communication?
There are two types of Submarine fibre cables: unrepeatered and repeatered. Unrepeatered cables are preferred in short cable routes because it does not require repeaters lowering costs however their maximum transmission distance is limited.

Are there fiber optic cables in the ocean?
Which cable is preferred for undersea communication single mode or multimode?
Single-mode fiber is capable of higher bandwidth and greater cable run distances (up to 3000 meters) than multimode fiber (up to 2000 meters only). Because of these characteristics single-mode fiber is often used for interbuilding connectivity or WANs (for example telephone company switch-to-switch connection).
Which cable is preferred for undersea communication graded index multimode?
How do undersea fiber optic cables work?
Where is multimode fiber used?
Applications of Multimode Fibers
Fiber bundles are used as laser delivery systems as a light source for illumination and as endoscopes – which have a long history in medicine and are also used for remote viewing in hostile environments such as nuclear reactors or pipe systems.
