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

QSFP-DD packages are favoured for 400G due to their high speed, small size, and pluggability, and 400G QSFP-DD optical modules have become one of the most popular optical modules when interconnecting next-generation data centre networks. With the standardisation of 400G, major vendors and suppliers

Docking principleThe basic principle of optical module docking is:Optical modules supporting the same standard can be docked (the standard has defined the rate, wavelength and distance, etc., but does not include the package format, the package of the optical module can be inconsistent when docking)

Optical modules are optoelectronic devices that perform photoelectric and electro-optical conversion. The transmitting end of the optical module converts electrical signals into optical signals, and the receiving end converts optical signals into electrical signals. Optical modules are classified ac
