Fiber Optical Networking

In the OSI model, we know that traditional network switches operate at Layer 2 while network routers operate at Layer 3. Besides, switches are understood to be forward traffic based on MAC address, while routers perform the forwarding based on IP address. Layer 3 switches have a lot in common with traditional routers: they can also support the same routing protocols, inspect incoming packets and make dynamic routing decisions based on the source and destination addresses inside. For this reason, many networking beginners are puzzled over the definition and purpose of a Layer 3 switch. So what is on earth Layer 3 switch and how is it different from router? Layer 3 Switch Layer 3 switch is also called multilayer switch. It is a specialized hardware device used in network routing, which is conceived as a technology to improve network routing performance on large local area networks (LANs) like corporate intranets. A Layer 3 switch is both a switch and a router. So Layer 3 switch i

As we all know, network switches are always a little bit noisy. Many people are bewildered by this problem. In fact, the noise mainly comes from the multiple fans that operate from within the network switch, in order to cool the various components of the switch from within. Considering the certain situation when some SMB might prefer having a fanless network switch, a brand new S2800-24T4F fanless switch has been introduced to meet the silent and cost-effective requirement for SMB customers. Let’s take a closer look at this energy-saving S2800-24T4F fanless switch. What Is Fanless Switch? In some scenarios, operating fans within the network switches is inevitable. It is the reason that the switches emanate so much heat, especially when multiple network switches are locked up into a rack along with many other active devices. At this time, fans play a important role to help cool various components within the network switch. However, the constant noise coming from the fans withi

Today, small and midsize businesses are embracing mobile and cloud technologies to improve employee productivity and engage with customers. More business needs an affordable, high-performance and secure wired and wireless infrastructure that can support the growing number of mobile devices and cloud-based applications. When asking for a recommendation for SMB switches, many people always recommend the HP because it has most of the same capabilities such as full management capability, rock solid operation and great support (as the Cisco), but at half the price. And HP 1810-48G switch is one of such SMB switches. This article intends to give a simple introduction to HP 1810-48G switch and provide compatible SFP transceiver solutions for it. HP 1810-48G Switch (J9660A) The HP 1810-48G switch is a basic smart managed Gigabit Ethernet Layer 2 switch that is designed for small businesses. This HP ProCurve 48 port gigabit switch has four additional true Gigabit Ethernet SFP ports (

According to a recent survey, over half (57%) of companies have already adopted the Internet of Things (IoT) technology. By 2019, that statistic is projected to reach 85% as the expectations for IoT to deliver value and innovation continue to grow. Many advocates are struggling to secure IoT devices. To lead the pack in the switches markets, Cisco recently announced the Catalyst 9500 Series switches, which are designed for security, IoT and the cloud. The switches will be the next generation of the most widely deployed switching platform. Here in this article will take you to understand more about Catalyst 9500 switches and which optical transceivers are compatible for it. Cisco Catalyst 9500 Switches - Built for Security, IoT, and Cloud The Cisco catalyst 9500 series switches are the next generation of enterprise-class core and aggregation layer switches, which are part of the new Cisco catalyst 9000 family. These switches come with 4-core 2.4-GHz CPU, 16-GB DDR4 memory and

A network switch is a small hardware device that centralizes communications among multiple connected devices within one local area network (LAN). Network switches come in different sizes, features and functions, so choosing a switch to match a particular network sometimes constitutes a daunting task. This blog will give you a few useful things to consider when choosing the appropriate switch for a layer in a particular network. Network Switch Technology While switching capabilities exist for several kinds of networks, including Ethernet, Fibre Channel, RapidIO, ATM, ITU-T G.hn and 802.11, network switch can operate at one or more layers of the OSI model. Switches provide multiple advantages in network designs. All switches provide the basic traffic filtering functions, which improves network bandwidth. Besides, the internal switching circuits allow traffic flows to simultaneously occur between multiple ports. Currently, mainstream network switches support Gigabit Ethernet sp
