Singlemode QSFP28 and Multimode QSFP28: Which One is Better?

To cater for people’s demands on higher bandwidth, lower cost, longer transmission distance, QSFP28 optics appears. Under common circumstances, optical transceivers can be divided in the form of single mode and multimode. Of course, QSFP28 optics are without exception. However, what are the differences between singlemode and multimode QSFP28 optics and which one is better? This article will have an…

Le pointeur laser est le meilleur outil pour l’astronomie

Je n’ai jamais utilisé un laser pointeur très faible pour les présentations internes, ce qui est une bonne préparation pour les caractéristiques de mon pointeur laser. Littéralement, je pense que je peux toucher la lune et les étoiles! La portée reportable de ce pointeur laser vert est de 80 km (50 miles). Le laser 5000mW est également facile à voir pendant la…

What Are the Differences Between QSFP28 and CFP Optics?

With the upgrade of optical network from 10G to 100G, the development trend of 10G-25G-100G/10G-25G-50G-100G starts to prevail in the optical market. In the development process of 100G optical transceivers, their  form factor type and standard are developed according to the cost and power consumption, which are regarded as the main drive in the development of interconnect market. QSFP28 is…

An Overview of DWDM: Definition, Advantages and Applications

When capacity expansion takes place in traditional network transmission, Time Division Multiplexer(TDM) and Space Division Multiplexer(SDM) are adopted. Both of transmission networks use a single wavelength signal for data transmission. However, this transmission method does not make full use of optical fibers with large capacity as transmission medium, resulting in a great waste. To deal with the issue, the DWDM…
