Difficulty: MediumNetwork Cable Types and Connectors

A network technician is setting up a high-density fiber patch panel to connect core switch ports via SFP+ transceivers. The installation specifications require a small form factor (SFF) optical fiber connector featuring a push-pull latching mechanism. Which of the following connector types should the technician terminate on the patch cables?

  1. LC (Lucent Connector)Answer
  2. B
    ST (Straight Tip)
  3. C
    SC (Subscriber Connector)
  4. D
    F-type connector

Answer

LC (Lucent Connector) is correct because it is a small form factor fiber optic connector with a push-pull latching tab designed for high-density network devices and SFP/SFP+ transceivers.
LC (Lucent Connector) is a small form factor (SFF) fiber optic connector utilizing a retaining tab latch mechanism similar to an RJ45 plug. Its compact footprint makes it the standard connector choice for SFP and SFP+ optical transceivers.

Step-by-Step Solution

1
Analyze the physical connectivity and form factor specifications in the scenario.
The requirement specifies an optical fiber connector with a small form factor (SFF) and a push-pull latch mechanism for SFP+ transceivers.
SFP+ transceivers require compact connectors due to high port density on switch line cards.
2
Compare candidate fiber connectors against form factor and latch mechanism requirements.
LC is SFF with a push-pull latch clip. ST uses a bayonet twist lock, SC is standard-sized, and F-type is coaxial.
Only the LC connector fulfills both the small form factor size constraint and push-pull latch requirement.
