This blog ETU-LINK takes everyone to understand the difference between optical fiber, copper cable and twisted pair. First of all, let’s understand the twisted pair. The twisted pair is made up of multiple groups of insulated copper wires intertwined. The internal medium of the twisted-pair cable is also copper wire, and the internal transmission is an electrical signal. According to the principle...

In this blog, ETU-LINK will introduce the selection and connection scheme of lower access layer switch and aggregation layer switch. In the three-tier architecture, the role of the access layer is mainly to connect end users to the network. The access layer switch is the equipment of the switching layer. Because the access layer switch needs to connect more end users, the price of the access layer...

The application of optical fiber patch cord is more and more widely, and it is often used in communication room, local area network, cable TV, light into the home and other system networks, but it is relatively fragile, so we need to be extra careful when wiring. So how should the optical fiber patch cord be connected? And what are the precautions in the use process?   Optical fiber patc...

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...
