With the progress of science and technology and the rapid development of data centers, the demand for high-speed optical communication modules is also growing. As a new type of high-speed optical communication module, 100G QSFP28 ER4 optical module is gradually receiving wide attention. In the previous articles, we have learned about 40G ER4 series optical module products, and today, we will follow Xiaoyi to look at the higher rate 100G ER4 optical module products.

I. Product information of 100G QSFP28 ER4 optical module

II.The working principle of 100G QSFP28ER4 optical module products

The 100G QSFP28 ER4 optical module is a 100Gb/s module designed for optical communication applications that comply with the Ethernet 100G BASE-ER4 standard. The 100G QSFP28 ER4 optical module adopts the QSFP28 Multi-Source Protocol (MSA) form factor and supports DDM digital diagnosis. It is designed to meet the harshest external operating conditions, including temperature, humidity and EMI interference.

The module converts four 25Gb/s electrical data inputs into four LAN WDM optical signals, which are then multiplexed into a single channel for 100Gb/s optical transmission. Instead, at the receiving end, the module demultiplexes the 100Gb/s optical input into four LAN WDM optical signal channels, which are then converted into four electrical signal output channels.

The central wavelengths of the four LAN WDM channels are 1295nm, 1300nm, 1304nm and 1309nm. The high-performance cooled DFB transmitter and highly sensitive APD receiver provide superior performance for 100G Ethernet applications, up to 30km links without FEC and 40km links with FEC.

III.Features and application scenarios of the 100G QSFP28 ER4 optical module

High-speed transmission: The 100Gbps transmission rate makes it ideal for processing large amounts of data and connecting different devices and servers, especially in data centers, cloud computing and other fields.

Long-distance transmission: The "Extended Range" that ER stands for means that it can transmit stably over a longer distance, usually up to 40 kilometers, which has significant advantages in long-distance communication environments, such as applications in optical communication backbone networks, and can also meet the needs of modern cities for communication speed.

Low power consumption: Compared with traditional optical modules, 100G QSFP28 ER4 optical modules usually have lower power consumption, which has a positive role in energy conservation and emission reduction.

Compatibility: 100G QSFP28 ER4 optical module It can be compatible with a variety of optical fibers and connection methods, making its application in different environments more flexible and diverse.

To sum up, 100G QSFP28 ER4 optical module as a high-performance optical module, is gradually becoming a popular choice in the field of optical communication, its high-speed, long-distance transmission and other characteristics make it play an important role in the data center, MAN connection, long-distance communication and other scenarios, but also provides a strong support for high-speed data transmission in the digital era.
