In this blog, ETU-Link will introduce what the fiber optic adapter is. And common types of fiber optic adapters.     Fiber optic adapters, also called flanges, are components that connect fiber-to-fiber or fiber-to-device. They are widely used in telecommunication networks, cable television networks, subscriber loop systems, and optical fiber link connections in regional networks. T...

一. Introduction to MPO Patch cord The MPO fiber optic patch cord is composed of a hot-swappable MPO connector and a multi-mode/single-mode fiber optic cable. The MPO optical fiber connector includes optical fiber, sheath, coupling components, metal ring, pin, dust cap, etc., and the pin part is divided into two forms: male and female. The male connector has two PIN pins, while the female connector...

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 article, ETU-LINK will take everyone into the optical fiber cabling system, which is simply the transmission network in buildings and complexes. The integrated wiring system is a digital infrastructure built by intelligent offices, which can support integrated applications such as voice, data, graphics, and multimedia. The integrated optical fiber wiring system is divided into the followin...

In this article, ETU-LINK will explain several problems that may occur after the optical fiber test is passed and the corresponding detailed analysis. (1) Why does the optical fiber test pass, but the packet is still lost when the network is running? In the standard selection, many users will make some obvious mistakes, such as not paying attention to whether the tested fiber is 50/125μm (OM2, OM3...

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...

Nowadays, video surveillance systems have become one of the indispensable infrastructures in all walks of life. With the popularization of high-definition and intelligent applications of video surveillance cameras, the requirements for video transmission signal quality, stream bandwidth and transmission distance have been improved. ETU-LINK will introduce to you today the use of PoE media converte...

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...
