For detailed answers to questions often encountered by 40G light modules

Today, I will share some questions and answer the 40G light modules and answer. Everyone knows that the competition between the mainstream optical communication transmission rate between 40g and 100G is quite fierce. Some issues.

Q: What are the general solutions for 40G networks?

Answer: In the center of the 40G network layer, a pair of optical modules (the most common is 40G QSFP+optical module) is generally connected to both ends of OM3 or OM4. The replacement plan is often used as the above -mentioned optical module and optical fiber in short -range interconnection.

Q: What are the packaging types of 40G light modules?

Answer: The encapsulation types of the 40G light module include CFP and QSFP+. Because of the large volume of CFP, the 40G optical module on the market is now QSFP+package.

Q: What is the maximum transmission interval supported by the 40G light module?

Answer: After the above form, we can clearly see that in several types of 40G light modules, the longest transmission interval is the 40G QSFP+ER4 light module, and its transmission interval can reach up to 40km. The scenes used by different transmission intervals are also different.

Question: What network is the 40G light module used?

Answer: These three 40G light modules are different because of different uses of various parameters.

40G QSFP+SR4 light module is mostly used in multi -mode applications, which is used to complete the short -range connection of data center devices. It can connect with the MTP/MPO jump line to complete the connection between two 40G network devices. The LC jumper uses the connection between 40G devices and 10G devices.

40G QSFP+LR4 light module and 40G QSFP+ER4 light module usually use WDM technology to complete the transmission of light signals on long -distance single -mode optical fiber.
