The rapid development of the Internet industry, mobile Internet access traffic growth, data traffic demand within the data center is doubled every year, resulting in increasing demand for data transmission to the development of high-speed rate, this article introduces the 200G QSFP-DD SR8 is one of the high-speed module.Figure：400G QSFP-DD200g optical module mainly QSFP-DD and QSFP56 two package t

PCI Express (PCIe) is a high-speed serial computer expansion bus standard that defines the physical and electrical characteristics of a data link between components on a motherboard. NVMe (Non-Volatile Memory Express) is a protocol designed for accessing storage devices, particularly solid-state drives (SSDs), through a PCIe interface. PCIe 4.0 and PCIe 5.0 are different generations of the PCIe st

40GBASE-SR4 and 40GBASE-CR4 are two different physical layer specifications within the Ethernet standard, each designed for specific network deployment scenarios. Here are the key differences between them:Medium:40GBASE-SR4: This standard uses multimode fiber optics as the transmission medium. SR stands for Short Range, and 40GBASE-SR4 is designed for relatively short-distance connections within d

QSFP56 and QSFP28 refer to different generations or variants of the QSFP (Quad Small Form-Factor Pluggable) transceiver module, each supporting different data rates and technologies. Here are the key differences between QSFP56 and QSFP28: Data Rates:QSFP28: QSFP28 supports data rates of up to 28 gigabits per second (Gbps) per lane. It is commonly used for 100 Gigabit Ethernet (100GbE) applica

SFP28 (Small Form-factor Pluggable 28) and QSFP28 (Quad Small Form-factor Pluggable 28) are both transceiver form factors used for high-speed network connections, but they differ in several key aspects:1.Size: SFP28 is a smaller form factor compared to QSFP28. SFP28 modules are designed for applications where space is limited, while QSFP28 modules are larger and designed for higher density applica
