What magic keywords am I looking for? When I search for fiber transceivers for Ubiquiti US-48s, Amazon says that there are only 3 models that exist. That can't be right.

Per the title. I'm looking for LC fiber transceivers on Amazon to go along with my US-48 switches but either 10Gtek and 6com are the only manufacturers on the planet or the search terms "LC transceiver ubiquiti us-48" are too restrictive.
