Q: What are the differences between 50G QSFP28 optical modules and QSFP+ optical modules?
A: The primary difference lies in the data rate, with 50G and 40Gbps respectively, and the QSFP28 package being smaller than QSFP+, making it more suitable for high-density applications. QSFP28 also supports more advanced modulation techniques such as PAM4.
Q: PAM4 technology in 50G QSFP28 optical modules
A: PAM4 technology refers to Pulse Amplitude Modulation, which enables the transmission of four signal levels per clock cycle, thereby achieving higher data rates on a single channel, and is a pivotal technology for realizing 50Gbps speeds.
Q: Hot-pluggable feature of 50G QSFP28 optical modules
A: The hot-pluggable support allows for module replacement without system shutdown, enhancing maintenance flexibility and system availability.
Q: Digital diagnostic capabilities of 50G QSFP28 optical modules
A: Offers digital diagnostic functions via the I2C interface, monitoring parameters such as temperature, voltage, optical power, etc., facilitating remote fault detection.
Q: Application of 50G QSFP28 optical modules in data centers
A: Widely used in intra-data center connectivity, including leaf-spine architectures, storage networks, server connections, and cloud services, providing high-bandwidth and low-latency links.
Q: 50G QSFP28 optical modules and future trends
A: Moving towards even higher speeds such as 100G/200G/400G, with optimizations for energy efficiency, lower costs, smaller sizes, enhanced compatibility, and richer intelligent management functionalities.
