We all know that fiber optic patch cords are widely used equipment connection accessories in the field of optical communications. It can connect a variety of network equipment and devices with fiber interfaces, such as optical modules, adapter panels, distribution boxes, wavelength division multiplexers and solutions. Multiplexers, fiber optic transceivers, etc. Next, ETU-LINK will intro...

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...

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...

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...

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 ...

The Internet cafe network system needs to have a high bandwidth and support a large amount of data transmission. Therefore, Internet cafes have higher requirements for network hardware. When designing the Internet cafe network, it is necessary to ensure a high-quality network transmission speed, and also consider future network upgrades and maintenance. Next, ETU-LINK will introduce network equipm...

SAN refers to the regional storage network, which needs to be connected by optical fiber, and the operation mode of the SAN mainly depends on the hardware. The structure of the SAN allows any server to connect to any storage array so that the server can directly access the data it needs no matter where it is located. Due to the optical fiber interface, the SAN also has a higher bandwidth. The SAN ...

The Fibre Channel switch originated from the Fibre Channel protocol. On the fourth layer of the Fibre Channel protocol, the Fibre Channel-based SCSI protocol for storage, the IP protocol for the network, and the virtual interface (VI) protocol for clusters mapped to the network architecture are established. Fibre Channel switches provide Fibre Channel switching for high-bandwidth and low-latency d...
