The advancement of technology and the rapid development of data centers have led to a growing demand for high-speed optical communication modules. 100G QSFP28 ER4 optical modules, as a new type of high-speed optical communication module, are gradually gaining widespread attention. In the previous issues, we have learned about 40G ER4 series optical modules. Now, this post will introduce the m

High Speed Cables As a low-cost alternative to optical modules for short distance connections, it is widely used in data centre interconnection scenarios such as SATA storage devices, RADI system scenarios, core routers, 10G or 40G Ethernet, etc. What are high-speed cables?Direct Attach Cable (DAC) is usually a cable assembly that is purchased in fixed lengths with fixed connectors at both en

SFTP (SSH File Transfer Protocol) transfer speed is affected by a number of factors, including but not limited to the following:Network Bandwidth: Network bandwidth is one of the main factors limiting SFTP transfer speed. If the network bandwidth is limited, then the data transfer speed will be restricted.Server Performance: SFTP transfer speed is also affected by server performance. If the server

QSFP-DD (Quad Small Form-factor Pluggable Double Density) and QSFP28 DD (Quad Small Form-factor Pluggable 28 Double Density) are both high-speed transceiver form factors used in data communication applications, but there are differences between the two:1. Physical Form Factor: QSFP-DD has a larger form factor compared to QSFP28 DD. QSFP-DD has a higher port density and can support up to 8 lanes of

QSFP-DD (Quad Small Form-factor Pluggable Double Density) and QSFP28 (Quad Small Form-factor Pluggable 28) are both types of transceiver modules used in high-speed networking applications, but they have some key differences.1. Size and Density:- QSFP-DD is a double-density form factor, which means it has a higher port density and can accommodate twice as many channels as QSFP28. It is physically l
