A new fiber patch panel uses the small square connector with a latch, the size commonly paired on modern equipment. Which connector is that?
Select an answer to reveal the explanation.
Short Explanation
The plug is the small square one you see clipped in pairs on current switches. You want an LC connector. The round bayonet plug, the larger square plug, and a coax thread are other connectors, and they are not this little latch.
Full Explanation
LC is the small square fiber connector with a latch, and modern patch panels and switch optics commonly use it, often as a pair in one clip. The panel in this build is asking for LC. ST is a bayonet fiber connector with a round body and a twist lock. It is not the small square latch. SC is a square push-pull fiber connector that is larger than LC. Calling SC the smaller square plug reverses the two. An F-type connector threads onto coaxial cable. It does not terminate fiber. Exam caveat: match single-mode or multimode to the equipment as well as the connector shape. An LC plug on the wrong fiber type still will not make a good link. Operational check: click the LC into the panel, confirm the latch holds, and check the link light on the optic. Cap the unused fiber port and confirm you did not mix a single-mode jumper onto a multimode panel. Check the link light after the latch clicks, and reclean the end if it stays dark. Dust the fiber end with a proper cleaner if the link light stays off after the latch seats.
