With the gradual improvement of living standards, the concept of networked and intelligent buildings is no longer unfamiliar to everyone. In intelligent buildings, we can not only exchange data information quickly, control lights and adjust air conditioning through the network system, but also build intelligent scenes such as network monitoring systems and intelligent parking systems. In order to ...

Fiber patch cords are widely used in the field of optical communications and optoelectronics. Insertion loss and return loss are two important indicators of fiber patch cords. Insertion loss will weaken the optical power in the optical link and reduce receiving sensitivity, while return loss will change the spectral width of the laser diode of the light source, introduce noise to the sys...

NAS storage network is a solution to meet the low-cost storage needs of small and medium-sized enterprises. Among them, NAS storage refers to network-attached storage, which is a device for storing data. It takes data as the center, completely separates storage devices and servers, and centrally manages data, thereby freeing up bandwidth, improving performance, reducing total cost of ownership, an...

Optical fiber testing is divided into primary testing and secondary testing. The primary testing is also the basic testing. It mainly tests the insertion loss (that is, attenuation) of the optical fiber and the length of the optical fiber link. No matter it is single-mode fiber or multi-mode fiber, they are all made of glass fiber, and natural loss will inevitably occur when optical pulse sig...
