40G QSFP+ LR4 optical modules are widely used in 40G networks, which contain two types of 40G QSFP+ LR4 CWDM4 optical modules and 40G QSFP+ LR4 PSM4 optical modules. The former is used to connect WDM links and the latter is used to connect parallel single-mode fibre links, but what is the difference

QSFP+ stands for Quad Small Form-Factor Pluggable Plus. A parallel and hot-swappable fiber optical module that provides high-density 40G connectivity options for high-performance computing networks and modern data centers. It has four independent receive and transmit optical channels that can termin

With the increased demand for faster and more reliable networks, 400G has become one of the most popular optical modules when interconnecting next-generation data centre networks.QSFP-DD is the 400G solution needed for next-generation cloud computing networks. To facilitate better network deployment

Eye Diagram (Eye Diagram) can show the quality of digital signal transmission, often used in electronic equipment, chip serial digital signals or high-speed digital signals in the need to test and verify the occasion, in the final analysis, is the quality of the digital signal is a fast and very int

Optical fibres are generally divided into single-mode fibres and multi-mode fibres, and this time we will mainly start with multi-mode fibres. Multimode fibre allows many different modes of transmission within it when transmitting signals, and the transmission distance is limited due to the effect o
