While there are a number of aspects that can be discussed in regards to optical switching technology, the focus of this article is to provide information about two key categories of optical switches – symmetric and asymmetric. The concept is very straightforward, but still important to understand when determining which [ Continue reading…]
There are many scenarios in today’s networks that require the replication of an optical signal, also known as optical multicast. Some of those scenarios include video feeds or data streams that need to reach multiple endpoints simultaneously. In other scenarios an expensive 40/100Gbps port may need to be replicated. In [ Continue reading…]
Prior to deploying new equipment into a live fiber optic network, communications equipment manufacturers, service providers, and carriers must ensure that their systems will work exact as intended. As a result, these organizations strive to exactly simulate the live network in a laboratory environment. While the consensus in the industry agrees [ Continue reading…]
Learning to operate an OTDR properly is a critical skill for field technicians managing and servicing fiber optic networks. The OTDR is used frequently to determine length and loss characteristics, including testing optical fibers for faults and related issues that can negatively affect network performance. There are a number of excellent [ Continue reading…]
As the use of fiber optic equipment in communications systems continues to grow worldwide, network simulation testing has become vitally important for vendors seeking to offer their equipment for use in the field. In the past, many engineers and technicians wold simply use exposed bare optical fiber spools that [ Continue reading…]
Chromatic dispersion is a phenomenon that is an important factor in fiber optic communications. It is the result of the different colors, or wavelengths, in a light beam arriving at their destination at slightly different times. The result is a spreading, or dispersion, of the on-off light pulses that convey digital [ Continue reading…]
If your company is like most that are involved with building or utilizing fiber optic systems, chances are you have a few spools of bare optical fiber laying around the lab. Since it is critical to ensure fiber-based equipment works as intended prior to deployment in the field, it is a [ Continue reading…]
The most common multimode optical fibers, which allow multiple light modes to propogate along the link simultaneously, are designed with a core diameter size of 50µm for for high-speed communications networks. You may recognize these types of fibers by industry specifications such as OM2, OM3, and OM4 or by brand names [ Continue reading…]
With the explosion of CWDM, it is very necessary to formulate a basic testing procedure to certifying and troubleshooting CWDM networks during installation and maintenance. Today, one of the most commonly available test methods is the use of an OTDR or power source and meter, which is capable of testing [ Continue reading…]
Nowadays, the demand for high connection speeds is increasing at an intimidating pace. People need to send -and receive- more data than ever, and the technology that’s available to them often seems to just not being able to keep up. Optical fiber seems to represent the best choice when [ Continue reading…]
