The QSFP-DD 400G LR4 optical transceiver can reach up to 10 kilometers (6.2 miles). This makes it suitable for long-distance data transmission in high-speed networking applications.Why QSFP-DD over other 400G capable form factors (OSFP, CFP8, & COBO)?When compared to the octal small form pluggable (OSFP), the QSFP-DD is quite similar. Both utilize eight lanes to achieve 400G data rates (8x50G)

Quad Small Form-Factor Pluggable (QSFP) transceivers offer several advantages in data centers, making them a popular choice for high-speed data transmission. Here are some of the key advantages:Higher Data Rates: QSFP transceivers support higher data rates compared to traditional transceivers. They are designed to handle speeds of 40 Gbps, 100 Gbps, and beyond. This allows for faster and more effi

Selecting the right Passive Power over Ethernet (PoE) solution is crucial for optimizing network performance and meeting specific power requirements. The choice of a passive PoE injector, switch, or power supply device can significantly impact the overall efficiency of the network setup. This guide provides detailed insights into the factors to consider when choosing these components, their suitab

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
