Does the optical module come with a cable
Optical modules typically have an electrical interface on the side that connects to the inside of the system and an optical interface on the side that connects to the outside world through a fiber optic cable. An optical module is a typically hot-pluggable optical transceiver used in high-bandwidth data communications applications. It changes electrical signals into light signals and back again. This helps data travel faster and farther than with copper cables. That is, metal medium communication represented by coaxial cables and network cables is gradually being replaced by optical fiber media.
