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.

Designed to be used in diverse applications, two types of optical fiber are available on the market; one is SMF or single-mode fiber, and the second is MMF or multimode fiber. This article will help our readers understand significant differences between multimode and single-mode type fibers.

By definition, a media converter is a flexible and cost-effective device designed to implement fiber links in almost every kind of network. Today, we have different types of media converters available on the market. The most often deployed type of media converter is a device that acts as a transceiver, which translates the electrical signals to light waves. Fiber optic connectivity becomes inevitable where the distances between two or more networking devices are greater than copper cable's transmission distances. Now let us discuss the benefits of media converters.

The designers and operators of data communication systems are looking for newer solutions to curtail with the ever-growing bandwidth demand and to maximize the reliability of data transmission.  One such system called FEC (forward error correction) has been proven pretty suitable. It's a technology that's been around for a long time to ensure effective data transfer over noisy channels. Let's study more about the FEC and its significance in optical networks where transmission volume and distance are increasing.

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.
