Power over Ethernet (PoE) is a proven technology that saves money and time. With PoE, we can transmit power and data over the same network cable in local area networks (LANs). The following three types of PoE switches are currently available on the market;

Ongoing innovation in IT and the incorporation of newer technologies are driving the demand for faster speeds and higher bandwidth. To cater to these requirements, data center engineers test ways to connect a maximum number of network devices. Link aggregation group (LAG) is one solution using which we can merge multiple Ethernet links to create a single logical link to improve data transmission efficiency. Both vPC and MLAG allow LAG creation, but each has pros and cons. Let us discuss vPC, MLAG, and their differences.

High-speed 40G QSFP+ DAC cables and QSFP+ optical modules can be used as solutions for 40G networking at the data center level. 40G QSFP+ DAC high-speed cable applications mainly include short-distance transmission in data centers and convenient wiring. Whereas, Optical modules can provide communication over long and short distances at rates even beyond 40G.

The communication systems are advancing day by day due to emerging global trends. So, to cope with the needs of the customers' various types of communication cables are available in the market. Each variety of cable is appropriate for its applications. They all are featured well to perform well. Then why is there a distinction among them? Which features create differences? To answer these questions, let's have a detailed discussion on networking and communication cables.

Passive optical network (PON) technology was introduced in the mid-1990s. After that, PON technology underwent rapid development - it started with ATM PON (APON) and then evolved into Broadband PON (or BPON). Later, EPON (Ethernet PON) and GPON (Gigabit PON) entered the market, bringing significant improvements in transmission bandwidth and distance. In this paper, we will discuss the basics of GPON technology.

Following its official launch, 5G is rapidly gaining momentum worldwide, especially in Europe, North America and Asia. Various network bodies have predicted rapid growth in 5G connections in the coming years. According to one report, investments of around $1.1 trillion are expected between 2020 and 2025, of which around 80% will be attributable to 5G CAPEX alone (see figure below).

Transmission is at the height of progress and flourishing day by day, which shows it will change telecommunication effectively. According to the statistics, global optics fiber was valued at about USD 2.75 billion in 2016. Fiber optic transmission is becoming popular daily due to its intensive use in the industrial and residential sectors. This blog will discuss the pros and cons of optic fiber in detail. So, what are you waiting for? Let's go ahead.

Being the smallest of commercially available 400G form factors, QSFP-DD provides the greatest bandwidth density in the market while offering compatibility to various lower-speed QSFP pluggable transceivers and cables as well. QSFP-DD is frequently compared with other optical modules such as OSFP, COBO, CFP8, and QSFP56 when it comes to 400G applications. In this post, we will learn about the differences between QSFP-DD and other modules, their structure, advantages, and disadvantages.

The electrical circuitry of the SFP transceiver modules is connected to copper or optical network. This type of transceivers is widely used for both data communications and telecommunication applications. Any official standards organization does not regularize the fiber optic SFP. The construction and specifications of this form-factor are specified by an MSA (multisource agreement) between competing manufacturers. SFP transceivers are readily available in a diverse range of options.

According to various studies, 100G will be dominating the market of network equipment in the future. However, in today`s scenario, 100G technology is still in its development phase. Users, planning to construct 100G long-haul network infrastructure often met some design challenges. For example, the QSFP28 optics currently available on the market (QSFP28 100GBASE-LR4) can support up to 10 km only with WDM technology.
