What are the IEEE 802.3 Ethernet Test Standards?


What is the Ethernet?

Ethernet technology is a family of computer area networks that is a very common interface in home and work environments. It can connect desktops, laptops, and servers to network routers or switches. Ethernet is classified in the IEEE 802.3 specification. It is also the oldest and most commonly used interface in the market. In order to meet market demand, its performance, transmission distance, and interoperability are constantly improving. The current highest specification has reached 400G transmission speed.

Who is the IEEE?

The Institute of Electrical and Electronics Engineers (IEEE) is the world’s largest professional association, whose purpose is to create a more advanced ecological environment for the world. This association gathers and actively develops technological innovation and is committed to voice standard formulation in the fields of electrical machinery, technological computing, and information communication.

Ethernet FAQ

Pretest preparation

1. What needs to be provided before Ethernet testing?
  • 2 sets of samples
  • A completed copy of the one-page product information form <Click to Download>

For more information, please refer to the Ethernet Test Process page.

2. How should Ethernet test samples be prepared?

Before testing, please confirm that your product can enter the test mode smoothly. The test needs to be carried out in the test mode. Please provide GRL with the method to enter the test mode. Please contact us before the test if there are any questions.

During test period

1. Is it necessary to turn off products that support low power mode during testing?

During the test, the time for each item is at least 5 minutes up. If the product supports Low Power Mode, your product must be able to turn off Low Power Mode to avoid interrupting the test. The test result will be Failed if the product enters sleep or standby mode before it runs out of the test item.

Posttest checklist

1. Can product samples be recollected upon test completion?


If your product is very special, GRL might investigate your consent and keep samples for 2 months.
