Ako fungujú podmorské káble?

Ako fungujú podmorské káble? underwater submarine optical fiber cable Submarine optical cables are actually optical fibers, which use the propagation characteristics of light in optical fibers to transmit data. Avšak, the submarine optical cable is not a simple optical fiber, it is actually a complex transmission system. The submarine optical cable system consists of two parts: underwater equipment and shore equipment. Underwater equipment It mainly includes optical cable, optical amplifier/repeater and underwater branch unit. What is the repeater used for? As we all know, despite the high speed and sufficient bandwidth of optical fiber, the signal transmission distance is...

Kroky, ako podmorský robot opraví podmorský kábel

The steps of how the submarine robot repairs the submarine cable The importance of submarine cables The reason why people can communicate and surf the Internet across the mountains and the sea is due to the role of submarine optical cables. Podmorský optický kábel, tiež známy ako podmorský komunikačný kábel, je drôt obalený izolačným materiálom a položený na morské dno na vytvorenie telekomunikačného prenosu medzi krajinami. Podmorský optický kábel sa zaväzuje 90% súčasného medzinárodného komunikačného biznisu vo svete a je hlavným nositeľom informačnej komunikácie v dnešnom svete. V súčasnosti, there are about...
