Switches are an integral part of modern networks, which enable communication between network devices and cables. They are especially useful in mixed or blended networks such as fiber optic and copper cable network. Industrial Ethernet switches are different and more advanced than regular switches. They are robust and are designed to resist harsh weather conditions, industrial environments, and so on. These are manufactured under special industrial grade standards and have a wide operating temperature range. When selecting Ethernet switches, there are many factors one must consider. This post d...

Differences between PoE, PoE+ and PoE++ SwitchesThe following are some important pointers that will help you understand the difference between these switches.One of the major differences between PoE, PoE+, and PoE++ switches is the IEEE standards. A PoE switch is designed as per 802.3af, PoE+ as per 802.3at, and PoE++ as per 802.3bt.Next, Ethernet cabling is an important consideration when differentiating these switches. PoE switch use two pair twisted cables, and the same goes for the PoE+ network switch. On the other hand, PoE++ uses four pairs of twisted cables. Differences among these...

PoE(Power over Ethernet) technology enables data and power transmission over a single cable through separate lines and is mainly designed for wired Ethernet as well as fiber optic networks. As far as fiber optic networks are concerned, you can connect a PoE switch and use a media converter along with it for transmission signal conversion. PoE is gaining momentum owing to the simplicity and efficiency it assures, and saves on external electric supplies for powering devices. There are different versions of Power over Ethernet switches in use today – PoE switches, PoE+ switches, an...

Know why fiber opc cable is better than copper cableBuilding a network with huge bandwidth and higher transmission speed has emerged as a key requirement in recent years. To accomplish this, several network cables have been used over the years. Traditionally, copper cables are widely used which are now being connected to fiber optic cables for better connectivity and geographical network expansion. In the case of new networks, especially in application where high-speed internet is a prerequisite, only fiber optic cables can be used entirely. Both cables offer unique advantages and specific ben...

As can be seen from the word, DCI refers to the network connection of two or more data centers. Depending on the distance and transmission capacity, engineer can use a variety of different technologies for interconnection, which is a broad concept. DCI can be built from the optical layer, using switches and routers. DCI generally refers to the interconnection of different data centers of operators, or the interconnection of enterprise-level data centers. In 2022, the demand for cloud services will explode, and the capacity, cost of data center interconnection will become several key points. Op...

1. Introduction Optical fiber sensing takes advantage of the physical properties of light as it passes through the optical fiber to detect changes in temperature, strain and other parameters. Optical fiber has wide working frequency band and large dynamic range, which is suitable for remote measurement and remote control. It is an excellent low loss transmission line. Under certain conditions, optical fiber is particularly easy to accept the measured or field loading, and is an excellent sensing element. The optical fiber is electrically neutral, small in size, light in weight, ...

It is universally acknowledged that optical transceiver is widely used in the data center. That is because optical transceiver is playing a major role on data transmission. Therefore this article is written for make a brief introduction about data transmission. Descriptionthe Data transmission, also referred to as digital transmission or digital communications, is the movement of data over a communication medium from one device to another. In the form of a digital bitstream or a digitized analog signal, the process of data transmission is applied in different channels: point to point, poi...
