Technologies intended to increase the speed of networks continue to develop rapidly. Meanwhile, maintaining configuration flexibility and high port utilization is essential for equipment deployed at the intersections of traditional copper and newer optical fiber networks. 1000BASE-T copper SFP modules and 1000BASE-T Ethernet cables have become the best option to maximize port flexibility and maximum port utilization. This article will discuss the two available interconnection options between 100BASE-T Ethernet switches that come with SFP ports.

In today's telecommunications industry, SFP ports are found in various networking devices, including routers, network cards (NICs), switches, servers, and more. What is the Ethernet switch SFP port? What is the difference between an SFP port and an RJ45 port? This article provides a detailed description of SFP and RJ45 ports and their main differences.

For many years copper was the standard for transferring communications signals. In recent years copper wire has been replaced with a new system called fiber optics cables. You've probably heard of this technology and how it is used by many different industries, including communications, the military, aerospace, and medical robotics, to name a few. These cables allow for higher speeds of signal transfer, provide greater resistance to electromagnetic interference from radios, engines and other nearby cables, and are known for being much easier to maintain than copper wires.

Router and gateway are two confusing terms that often come during the discussion about communication and networking devices. We will try to provide our readers with some valuable information about the difference between network routers and gateways through this article. Before moving ahead, it is vital to understand the similarities between gateways and routers. Both devices come with the capability of regulating network traffic between two or more distinct networks.

The Metro Ethernet Forum (MEF) has specified a framework for delivering Ethernet services over carrier-grade networks. The framework specifies requirements for the network architectures, services and interfaces. The Ethernet Services are delivered from User-Network Interface to User-Network Interface (UNI to UNI). In addition, a set of standard Ethernet Services has been defined based on the framework. An Ethernet Service is defined in the framework by an abstract construct called the Ethernet Virtual Connection (EVC). The Service Framework associates a service instance with the UNI characteristics, at which the Service is offered, to the Subscriber and with the EVC supporting the Service. The MEF Ethernet services, expressed through the EVC construct, are defined in a manner that is agnostic to the specific technologies implementing them. However, the most common technologies used for supporting MEF services may not always provide full transparency with their transport services.
