Over the past few decades, communication network has undergone a milestone development, software defined network (SDN) is a new network structure which sprang up in recent years, it uses OpenFlow technology to separate control planes and data planes from network equipment, thereby to achieve flexibl

As we all know that the transmission distance of traditional Ethernet shielded / unshielded twisted pair is limited which only up of 100m. So Ethernet optical transceiver and optical cable are needed for achieving long-distance transmission of signals. This tutorial will explain the basic knowledge

With the growing demands for bandwidth that makes 100G network developed rapidly. 100G optical module is to be an important part of 100G network, and now many standards and form factors has been emerged on the market. Here we will introduce the related knowledge about 100G optical module in detail.T

For having a better understanding of optical modules and fiber connectors, this tutorial will introduce the application guideline of them, and we hope that this article will be helpful for you.Classification of moduleClassified by rate: 100BASE, 1000BASE, 10GE of Ethernet application; 155M, 622M, 2.

With the growing demands for data transmission rate, the market of 100G optical module is also expanding rapidly. IEEE organization was designed two optical module standards for 100G network: 100G SR4 QSFP28 and 100G LR4 QSFP28. However, in practical application, due to the diversity of optical fibe

According to the physical standard, Cisco SFP optical module can be divided into 1000BASE-T, 1000BASE-SX, 1000BASE-LX / LH, 1000BASE-EX, 1000BASE-ZX, 1000BASE-BX10-D / U optical module. The Cisco GLC-LH-SM optical module is a 1000BASE-LX / LH optical module, which will be covered in detail in this a

BNC interfaceBNC interface refers to the coaxial cable interface for 75 Euro coaxial cable connection to provide receiver (RX) and sender (TX) channels, which is used for unbalanced signal connection.Fiber interfaceThe fiber interface is the physical interface used to connect the fiber optical cable

With the rapid development of optical communication in recent years, users have increasing demands for the network. In this condition, 100G optical module has become the hot focus that users care. What is a 100G optical module? This post will give a complete introduction and guide about 100G optical

Distinction between SFP multi-mode and single-mode According to the wavelength, it can be divided into 850nm/1310nm/1550nm/1490nm/1530nm/1610nm. The one with wavelength of 850nm is SFP multi-mode with transmission distance of 2KM or less;The one with wavelength of 1310/1550nm is SFP single-mode with
