Optical cable is usually composed of one or more optical fibers. Optical fiber can transmit light signals through the principle of total reflection to achieve efficient transmission of information. Multi-core mini optical cable is a compact optical cable containing multiple optical fibers and is used where high-density optical fiber transmission is required.
