In the face of data explosion, how can the high-efficiency performance of the QSFP28-100G-ER4 optical module not make people shine?

In today's era of data explosion, high-speed and long-distance data transmission has become an indispensable requirement for all walks of life. In order to meet this demand, the QSFP28-100G-ER4 optical module came into being. With its performance and wide application scenarios, it has become a popular choice in the field of optical communications.

The QSFP28-100G-ER4 optical module is a 100Gb/s module designed for optical communication applications that comply with the Ethernet 100G BASE-ER4 standard. It adopts the form factor of the QSFP28 Multi-Source Agreement (MSA) and supports the DDM (Digital Diagnostic Monitoring) function to ensure the stability and maintainability of equipment operation. The module is well designed and can operate stably under harsh external working conditions (including temperature, humidity and EMI interference), providing reliable protection for key applications such as data centers and cloud computing.

The core advantage of the QSFP28-100G-ER4 optical module lies in its high-speed transmission and long-distance transmission capabilities. It uses wavelength division multiplexing (WDM) technology to send and receive data on four different wavelengths (1295nm, 1300nm, 1304nm and 1309nm), effectively improving the efficiency of optical fiber use and network bandwidth. This technology enables a single optical fiber to transmit four 25Gb/s electrical signals at the same time, and finally converge into a 100Gb/s optical signal for long-distance transmission, with a maximum transmission distance of up to 40 kilometers.

The working principle of the QSFP28-100G-ER4 optical module is relatively complex but efficient. At the transmitting end, it converts 4 25Gb/s electrical data inputs into 4 LAN WDM optical signals, and multiplexes these optical signals into a single channel for 100Gb/s optical transmission through a wavelength division multiplexer. At the receiving end, the module demultiplexes the received 100Gb/s optical signal into 4 LAN WDM optical signal channels, and then converts them into 4 electrical signal output channels. In this process, high-performance cooled DFB transmitters and highly sensitive APD receivers play a key role, ensuring high-quality signal transmission.

QSFP28-100G-ER4 optical modules are widely used in scenarios that require high-speed and long-distance data transmission, such as data centers, cloud computing, large enterprise networks, metropolitan area networks, and wide area networks. Inside the data center, it can achieve high-speed interconnection between different servers and switches, improving overall network performance. In cross-data center connections, QSFP28-100G-ER4 optical modules play an important role, supporting remote high-speed interconnection between data centers, and providing a convenient and economical solution for the expansion and upgrade of data centers.

QSFP28-100G-ER4 optical modules have become pioneers in the field of optical communications with their performance and a wide range of application scenarios. It can not only meet the current needs of high-speed and long-distance data transmission, but also provide a solid foundation for future network development. With the continuous advancement of technology and the continuous expansion of application scenarios, we have reason to believe that QSFP28-100G-ER4 optical modules will play a more important role in the field of optical communications.
