Armored patch cord is a new type of optical fiber patch cord designed with a layer of stainless steel sleeve to protect the optical fiber. It has the advantages and functions of standard optical fiber patch cord, but at the same time has the durability of armor. The following ETU-LINK will give you a detailed introduction to the advantages, types and uses of under-armored fiber optic patch co...

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...

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 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. ...

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...

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...
