QSFP28-100G-ER4 optical module: the preferred solution for high-speed and long-distance transmission

In today's era of data explosion, the demand for high-speed and long-distance data transmission is growing. In order to meet this demand, optical module technology is constantly innovating, among which the QSFP28-100G-ER4 optical module has become the focus of the industry with its excellent performance and wide application scenarios.

The QSFP28-100G-ER4 optical module is a high-speed optical communication module in the form of QSFP28 packaging, supporting a transmission rate of 100Gbps. The "ER" in "ER4" stands for Extended Range, and the "4" indicates that the module supports four wavelengths of optical signal transmission. This design enables the QSFP28-100G-ER4 optical module to achieve a transmission distance of up to 40 kilometers on a single-mode optical fiber, far exceeding traditional optical modules.

Technical features
High transmission rate: The QSFP28-100G-ER4 optical module supports a transmission rate of up to 100Gbps, meeting the needs of large-capacity data transmission. Whether it is Internet applications, cloud computing, big data or high-definition video transmission, it can be easily handled.
Long transmission distance: By adopting advanced wavelength division multiplexing (WDM) technology, the QSFP28-100G-ER4 optical module can achieve a transmission distance of 40 kilometers on single-mode optical fiber. This feature makes it perform well in scenarios such as data center interconnection, remote data backup and recovery, and cross-city network connection.
Low power consumption and high density: The QSFP28 packaging form gives the optical module the advantages of small size and low power consumption. In a commercial environment, its power consumption is usually less than 4.5W, and in an industrial environment it is only about 5.5W. This low power consumption feature not only meets the requirements of green energy saving, but also makes it suitable for high-density cabinets and environments with limited fiber installation.
Hot plug and play and compatibility: The QSFP28-100G-ER4 optical module supports hot plug operations for easy maintenance and upgrades. At the same time, it is also compatible with switches of various brands, such as Huawei, ZTE, Dell, Cisco, etc., providing users with a wider range of choices.

Application scenarios
Data center interconnection: With the rise of cloud computing and big data, the amount of data exchange between data centers has increased dramatically. The QSFP28-100G-ER4 optical module has become the preferred solution for data center interconnection due to its high transmission rate and long transmission distance. It can not only meet the transmission needs of large-capacity data, but also effectively reduce network latency and operating costs.
Remote data backup and recovery: For enterprises that need to remotely backup and restore data, the QSFP28-100G-ER4 optical module provides an efficient and reliable solution. It can maintain the integrity and stability of data during long-distance transmission, ensuring the smooth progress of backup and recovery operations.
Cross-city network connection: When building a cross-city or cross-regional network, transmission distance and transmission quality are two key factors. The QSFP28-100G-ER4 optical module provides strong support for cross-city network connections through its long transmission distance and high transmission rate.

With the rapid development of emerging technologies such as 5G, the Internet of Things, and artificial intelligence, the demand for high-speed and long-distance data transmission will continue to grow. As one of the key technologies to meet this demand, the QSFP28-100G-ER4 optical module has a broad market prospect. However, in the face of increasingly fierce market competition and changing user needs, optical module manufacturers need to continuously innovate and optimize product performance to provide more efficient and reliable solutions.
