400G ZR or 400ZR is a networking standard designed to enable 400GE transmission over Data Center Interconnect links. 400ZR supports up to 80 km links and it utilizes a technology called “Dense Wavelength Division Multiplexing”. 400G ZR tends to provide long-term, single-carrier 400G implementation through dual-polarization 16 QAM at around 60 gigabaud where 16 QAM stands for 16-state Quadrature Amplitude Modulation.

50/125μm and 62.5/125μm fibers are commonly referred to as multimode fibers. The inner diameter of the plastic or glass core inside the optical fiber cable is 50 micrometers and 62.5 micrometers, respectively. The light that encodes your data travels through the fiber core. The 125m refers to the cladding's diameter, which limits the light to the core. The two, available kinds of multimode optical fiber cables are shown in cross-section. Varying bandwidths will result from the different core sizes. Because of the reduced core size, there will be more bandwidth.

Many of us already know about Forward Error Correction (FEC) as it is widely used in the networking and data communication industry. You can find it in space communication, wireless networks, bar code scanners, undersea optical fiber network, and even in your CD players. In this post, we will discuss its crucial role that helps transceivers in achieving longer reaches.

A broad range of 10G SFP+ modules from Cisco has earned tremendous popularity and reputation over the past few years. In 10G Ethernet deployments and diverse networking environments, 10G modules from Cisco are quite popular. Back in 2014, the technology giant came ahead with a new range of S-Class modules such as SFP-10G-SR-S. this new series of optical modules brings more options for data centers and enterprises.

When it comes to network implementation, you may only think of pluggable optics secondarily. However, in recent years, high-performance and high-capacity pluggable transceivers have been developed to meet the growing bandwidth requirements in service provider and data centre networks. As a result, the design of pluggable modules and their communication with the host ports of routers and switches has become increasingly complex. Today, 100G optics are considered a viable solution to the design and hardware costs of our network fibre infrastructure.

Numerous tests are done by vendors during the designing and production phase of fiber patch cables to ensure the shipping of high-quality patch cables only. These optical fiber tests are crucial for every type of optical fiber network. It is necessary for the vendor as well as for end-users to learn and understand the tests which are done to determine the quality of the fiber patch cable and the result of these tests is evaluated to decide whether the fiber patch cables under consideration are suitable for your application or not. In this post we are going to talk about the three most important tests; insertion loss (IL) test, 3D metrology test, end-face clarity, and return loss (RL) test.  

Bandwidth-hungry endpoints are testing the limits of enterprise campus networks. These days networks are subject to smart devices that support rich content including High-Definition (HD) video and advanced devices. In this scenario, enterprises can secure their networks by increasing bandwidth while avoiding major hardware changes.

OM3 and OM4 optical fibers are two types of laser-optimized multimode fibers (MMF) with 50/125µm fiber core size which are manufactured in compliance with the requirements as described by the ISO 11801 standard. OM3 and OM4 fibers come with many similarities such as applications and connectors. many similarities between the OM3 and OM4 fibers make it confusing for the users that which one they should purchase and why? In this article, we will discuss the differences between these two types of optical fibers in terms of major technical aspects such as speed, transmission distance, bandwidth, etc.

5G has turned into a reality and we can see it gaining popularity with time. More and more internet-based applications are coming online. From banking to education and from entertainment to gaming – almost every industry is making full use of the internet. Throughout this decade we have seen an exponential growth both in the numbers of internet users and traffic. The popularity of video sharing services and video streaming services such as YouTube and Netflix have brought immense stress on internet service providers.

The entertainment industry is undergoing a massive transformation to accommodate the expectations of people who use the internet to access online resources through their internet enabled digital devices. The ongoing development taking place in the broadcasting industry gives viewers brand new experiences. Huge demands on wired infrastructure are also expected because of growing audiences. Let us talk about five broadcasting technology trends that are going to consume more fiber resources in the next decade.
