How to use a fiber optic coupler to an Ethernet port

Connecting Fiber Optic Cable to Ethernet Port: Carefully insert the fiber optic cable connector into the Ethernet port, aligning the keying mechanism if applicable. Ethernet ports are designed for copper cables (like Cat5e or Cat6), which transmit data using electrical signals. This video will tell you how to make the RJ45 port on the router to use with fiber.

Is an optical module a type of chip

An optical module is a typically hot-pluggable optical transceiver used in high-bandwidth data communications applications. 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. The form factor and electrical interface are often specified by an interested group using a (MSA). Optical modules can either plug into a front pa. [pdf]
