Group of answer choices

LR4

TX

T

LX

Answer 1

The two IEEE standards for Ethernet technologies that indicate the use of fiber are:

1. **LR4** - This standard refers to Long Range 4, which is designed for use over single-mode fiber.

2. **LX** - This is another standard indicating a fiber optic connection, typically for use with long wavelength signals on single-mode fiber.

So, the correct choices are **LR4** and **LX**.
