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...

The optical communications industry entered 2020 with very strong momentum. Demand for DWDM, Ethernet, and wireless fronthaul connectivity surged at the end of 2019, and major shifts to work-at-home and school-at-home in 2020 and 2021 due to the COVID-19 pandemic created even stronger demand for faster, more ubiquitous, higher reliability networks. While supply chain disruptions continued, the industry was able to largely overcome them, and the market for optical components and modules saw strong growth in 2020 and 2021, as shown in the figure below.We believe the transceiver market is on trac...

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...

LightCounting’s Access Optics Report describes the market outlook for both Fiber-to-the-X (FTTx) optics and wireless fronthaul, midhaul, and backhaul network optics. In aggregate, LightCounting estimates that the access optics market will reach 127 million devices shipped, and $1.77 billion in revenues in 2022 (Figure 1). FTTx devices will account for roughly three-quarters of shipments and 49% of revenues. Fronthaul transceivers account for 22% of unit shipments and 40% of total revenues.Annual revenues for access optics are expected to total $1.4 to $1.6 billion through 2027, cycling down fo...

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...

Owing to the growing demand and quality requirements of the optical transceivers, testing their performance is necessary and important. Fiber optics is a multi-parameter technology, so several factors must be considered while testing the optical transceivers. This post discusses different parameters and introduces testing methods of fiber optic transceivers. An optical transceiver features a transmitter and a receiver, so it is important to test this equipment for individual functionality. Different Techniques of Transmitter Testing and Receiver TestingLet us focus on different ...

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...

In the 5G era, Chinese companies have achieved the catch up of network technology—5G patents are the first in the world. Now many countries are developing 6G, and Chinese companies are also taking the lead in layout. The latest research shows that the 6G patents applied by China account for nearly 50% of the world, far ahead of other companies.The research institution called Market Research Future (MRFR) recently released the 6G Market Research Analysis Report, which shows that nearly 50% of the world's 6G patent applications come from China, and the rest from other countrie...
