The Road to 400G: How PAM4 Modulation Is Transforming Optical Networking Global consumers of data continue to show increasingly insatiable demand for bandwidth. Since the existence of 100G, there had been expectations of better bandwidth technology, 200G, with faster transmission and signals. With such advancements, it is inarguable that the need for 400G within the…
The Rise of QSFP – 40GbE to 400GbE and Beyond The network infrastructure industry is testing 400GbE products and is anticipating the construction of next generation systems. A couple of years ago, there were arguments in the industry about the “correct” pluggable factor of form for 400GbE. But, it seems like that argument has ended,…
Solving Datacenter Network Bandwidth with 400GB Fiber Optics Datacenter networks are running into traffic problems because of the increase in data density in recent years. Since 2012, advancements in cloud storage, social media, messaging, large chunks of data, and content distribution networks have contributed to network IP traffic. Data transmissions have doubled by at least…
4 Ways to Segregate a Network – Enterprise IT Infrastructure Do you need to segregate? Most situations in which you need to segregate are related to the security of your network. The main reason for segregation is to limit access to the network that a group of users or devices may have. This ensures that…
Comparing Active and Passive Optical Networks FTTH (Fiber to the Home) access networks are widely deployed in homes across many countries. Today, more and more subscribers are using optical fibers rather than copper lines for broadband Internet access. FTTH is the most advanced form of fiber-optic communication which you can avail of in your living…
6 Reasons to Upgrade Your Network Infrastructure Network traffic is going to increase with the growth of IoT but many networks aren’t ready for it. Here’s 6 reasons why you might need an upgrade. Reason #1: The network traffic is going to increase – is your network infrastructure ready for it? As you are…
Big Data: Single-mode or Multi-mode in the Data Centre? One of the biggest reasons for the huge demand for Big Data these days is the increasing use of the concept of the Internet of Things (IoT). IoT is today much more than just a concept – it is a part of everyday life and there…
Optical Transmission in Data Communication (Part 2/2) One major issue with copper wires is that any signals sent through them can be subjected to electromagnetic interference (EMI) or signal noise as it is called. The interference is because of a number of reasons. It could be because of the electrical motors or the power lines.…
Optical Transmission in Data Communication (Part 1/2) There are situations when using fiber optic transmission makes sense and has many unique benefits. Fiber optics are much needed in data centers and also to handle data communication in a range of industries such as automation, aerospace, petrochemical, automotive and utilities. Here are some of the advantages of…
Optical Fiber vs. Copper Wires for Data Communication Optical transmission or fiber optic communications involves transmitting data in the form of pulses of light through extremely thin strands of glass. Optical fibers are extremely thin, with a thickness that can be compared with that of a human hair. They transmit light from one end to…
