CompTIA®A+ Exam Notes : Identify The Various Types Of Network Cables And Connectors

2. Networking

2.1 Identify the various types of network cables and connectors.

The connector types commonly used for Fiber Optic networking are SC,ST, or MIC connectors. IDC/UDC is used in Token Ring networks. RJ-45, BNC connectors are commonly used in Ethernet networking.

1. ST connectors are the most common type of commercial fiber optic connector. These connectors utilize an exposed plastic tube housing the optical fiber. This requires a connection to a matching cable on the other side, incorporating a connector that mates to the other. These combine in a spring-loaded twist, reminiscent of BNC connectors, and are noted for their reliability.

2. SC connectors have the ferrule that houses the fiber mostly concealed. Probably the most similar commercial equivalent of To slink, SC connectors does not require a mating cable on the other side. Instead, these snap-on connectors simply push into their jacks with a click.

3. FC connector is similar to ST connectors, these fiber optic connector's screws into their mating jacks. Additionally, the tube surrounding the optical fiber is typically shrouded in ceramic or metal, as opposed to being fully exposed. The inner ring of the connector is keyed to ensure positive mating to its corresponding jack.
