A technician is terminating a fiber optic patch cable and needs to select a connector type that uses a small push-pull latching mechanism, allowing higher port density on a patch panel compared to older connector types. Which of the following connector types should the technician choose?
- AF-type
- BST
- CLC
- DSC
Show answer & explanationAnswer & explanation
Correct answer: C. LC
The LC (Lucent Connector) is a small-form-factor fiber connector with a push-pull latch, allowing twice the port density of SC connectors on a patch panel. ST connectors use a twist-lock mechanism and are larger, SC connectors use a push-pull mechanism but are larger than LC, and F-type is used for coaxial cable, not fiber.
Why the other options are wrong
- A. F-type connectors are used for coaxial cable, not fiber optics.
- B. ST connectors use a twist-and-lock bayonet mechanism and are bulkier.
- D. SC connectors use push-pull latching but are larger than LC, reducing density.
LC Fiber Connector
LC (Lucent Connector) is a small-form-factor fiber optic connector with a push-pull latch, enabling higher density than SC or ST connectors.
- Small form factor, high density
- Push-pull latching mechanism
- Common in modern fiber patch panels
Memory trick: 'L'C is 'L'ittle, so more fit on a panel.
