Use Case for 10G/40G Switch-to-Switch Interconnect

In addition to 10 GbE, the telecom market nowadays is also actively deploying 40 GbE connections to support server connectivity, the typical use case is switch-to-switch interconnects. In fact, copper cables is used in some special cases, primarily for switch-to-switch short-reach connections. However, with the majority of 40 GbE connections being optic fiber-based, fiber optic cables, especially the MTP/MPO cables are widely deployed. From a cable plant standpoint, continued investment in fiber parallel-optic technologies will position the physical infrastructure for eventual migration to 100 GbE and beyond. This article will…

RJ45 Connector Used in Ethernet Connectivity

Have you ever noticed the copper cable plugged into your computer? Or to put it specifically, the crystal connector in your computer? That’s what we called RJ45 connector. It’s a common component used to connect computers into Ethernet-based local area networks (LAN). But how much do you know about this simple connector? Let’s get together to make sense what it looks like and how to terminate Ethernet cable with it. RJ45 Connector Overview RJ45 connector is the most common twisted-pair connector for Ethernet cables and networks. The letter “RJ” represents…

Two Major Prerequisites for Effective Communication

There are two major  prerequisites in order to have a successful communication, let it be between two living things or between two machines. Understandability is the first prerequisite. The transmitter and the receiver should speak the same language. If I speak in my mother tongue, which is different from the one that the receiver speaks and understands, there must be a translator. If the languages are different and if there is no translator, there is no understandability in that communication. If the transmitter and receiver speak different languages and they…

Introduction to Fiber Optic Patch Cables in Gigabit Optical Communications

As the medium of transmission in telecommunications infrastructure, fiber optic patch cables have gradually replaced copper wires in many telecommunication applications for the transmission of high-speed voice, video, and data traffic in enterprise and service provider networks. A fiber optic patch cable, often called fiber optic patch cord or fiber jumper cable, is a fiber optic cable made of glass and capped at either end with connectors. Depending on the type of application and the length to be achieved, various types of fiber may be considered and deployed. This paper…
