Huawei SFP-10G-CU3M High Speed Cable Sample Report

High-speed cables, often also known as DAC, Direct Attach Copper Cable, are cables with integrated connectors and copper cables, which are easy and simple to use. High-speed cables can be directly connected to the optical interface of the device to use, and the difference with the AOC fiber optic cable is that the high-speed cable uses copper cable in the middle, and the signal is transmitted through the copper wire, while the AOC fiber optic cable is transmitted through the optical fiber.

Huawei company has a model SFP-10G-CU3M high-speed cable products, can support 10G Ethernet short distance applications, Moduletek Laboratory prototype testing of the product, to facilitate further understanding of the product's performance indicators and the effect of the actual machine use.

1. Product Description

Huawei SFP-10G-CU3M high-speed cable supports 3M link length on 10G copper cable. The official key parameters and the physical appearance of the module are as follows:

3. Module Key Parameter Test

3.1 S-parameter Test

The S parameters of the modules at both ends of the cable are tested using a network analyzer under normal temperature conditions, and the test results are as follows;

3.2 Impedance Test

The differential impedance of the modules at both ends of the cable is tested using an oscilloscope at room temperature, and the test results are as follows;
