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...

In 40G short-distance optical network transmission, the conventional optical module solution is to use QSFP-40G-SR4 optical module and 12-core MPO multi-mode OM3 fiber patch cord. Although this solution can realize the upgrade of 10G network to 40G network, it uses MPO branch jumpers to connect 10G equipment and 40G equipment are obviously too expensive, so the industry has given a new optica...

The Fibre Channel protocol was formulated by the X3T11 team of ANSI in 1988. It has the characteristics of high bandwidth, multi-media, and long-distance transmission. It can realize the transmission of large data files between storage, server and client nodes. In this article, ETU-LINK will focus on introducing the 16G FC DWDM SFP+ series optical modules for 16G Fibre Channel networks. ...

We all know that a switch is a network device used to forward electrical (optical) signals, while a router is a hardware device that connects two or more networks. It acts as a gateway between networks and reads the data in each packet. The address then determines how to transmit the dedicated intelligent network device. Next, ETU-LINK will give you a detailed introduction to the differences ...

The OM3 patch cord is a 10-Gigabit multi-mode patch cord. The multi-mode fiber uses light-emitting diodes as the light source, allowing multiple beams of light to propagate in the fiber at the same time, thereby forming a mode dispersion. Mode dispersion technology limits the bandwidth and distance of multimode fiber. Therefore, the core wire of multimode fiber is thick, the transmission speed is ...

We need to pay attention to the two parameters of transmit optical power and receiving sensitivity when purchasing optical modules, because these two parameters are one of the key factors to ensure the normal communication of optical modules. Next, ETU-LINK will introduce to you what are the transmitted optical power and the receiving sensitivity? And how to test the optical power of the optical m...
