Which of the following fiber connector types is the most likely to be used on a network interface card?
Correct Answer: A
* Definition of Fiber Connector Types:
* LC (Lucent Connector): A small form-factor fiber optic connector with a push-pull latching mechanism, commonly used for high-density applications.
* SC (Subscriber Connector or Standard Connector): A larger form-factor connector with a push-pull latching mechanism, often used in datacom and telecom applications.
* ST (Straight Tip): A bayonet-style connector, typically used in multimode fiber optic networks.
* MPO (Multi-fiber Push On): A connector designed to support multiple fibers (typically 12 or 24
* fibers), used in high-density cabling environments.
* Common Usage:
* LC Connectors: Due to their small size, LC connectors are widely used in network interface cards (NICs) and high-density environments such as data centers. They allow for more connections in a smaller space compared to SC and ST connectors.
* SC and ST Connectors: These are larger and more commonly used in patch panels and older fiber installations but are less suitable for high-density applications.
* MPO Connectors: Primarily used for trunk cables in data centers and high-density applications but not typically on individual network interface cards.
* Selection Criteria:
* The small form-factor and high-density capabilities of LC connectors make them the preferred choice for network interface cards, where space and connection density are critical considerations.
