QSFP28-100G-ER4: Pioneer in the new era of high-speed optical communication

With the rapid development of science and technology and the continuous expansion of data centers, the demand for high-speed optical communication modules is increasing. Among the many optical modules, QSFP28-100G-ER4 is gradually becoming a popular choice in the field of optical communication due to its performance and wide application scenarios.

The QSFP28-100G-ER4 optical module is a high-speed optical communication module designed for optical communication applications that meet the Ethernet 100G BASE-ER4 standard. It adopts the QSFP28 (Quad Small Form-factor Pluggable) packaging form and supports high-density and low-power transmission characteristics. Among them, "ER" stands for Extended Reach, which means that the module can be stably transmitted over a long distance.

The working principle of the QSFP28-100G-ER4 optical module is relatively complicated, but in short, it converts electrical signals into optical signals for transmission and converts optical signals back to electrical signals at the receiving end. Specifically, the module converts 4 25Gb/s electrical data inputs into 4 LAN WDM (LAN wavelength division multiplexing) optical signals, which are then multiplexed into a single channel for 100Gb/s optical transmission. At the receiving end, the module demultiplexes the 100Gb/s optical input into 4 LAN WDM optical signal channels, which are then converted into 4 electrical signal output channels.

QSFP28-100G-ER4 optical modules play an important role in data centers, metropolitan area network connections, long-distance communications and other scenarios due to their high-speed and long-distance transmission characteristics.

Data Center: Within the data center, the QSFP28-100G-ER4 optical module supports 100G Ethernet applications, enabling high-speed interconnection between devices within the data center. At the same time, it also supports OTU4 optical transport networks, providing a convenient and economical solution for remote high-speed interconnection between data centers.
Metropolitan Area Network Connection: In the metropolitan area network, the QSFP28-100G-ER4 optical module enables remote high-speed connections between data centers in different geographical locations. Through single-mode optical fiber, the module can transmit up to 40km, providing stable and reliable guarantee for data transmission between cities.
Long-distance communication: In the optical communication backbone network, the QSFP28-100G-ER4 optical module also performs well. It can not only meet the demand for communication speed in modern cities, but also reduce the complexity of networking, reduce relay equipment, and thus reduce maintenance costs.
