When supporting high-usage services, there is always a chance for service disruption, which directly impacts the customers. When service outages arise, service providers and businesses are in a reactionary position while attempting to locate the system failure. Depending on the structure of the troubleshooting protocol for a service provider or business, there can be many steps taken before a technician is deployed. Once the technician is deployed, there still is a chance that challenged can arise for them locating the exact fault.

Benchmarking is the evaluation of a performance in contrast to a standard, typically based on best processes and organizations in your industry. Typically bench marking revolves around key factors which are cost, time and quality. When considering communications systems of fiber optics, bench marking refers to the quality of performance of the information that is delivered. It is also a tremendously noteworthy impact on cost as well as time.

Fiber optic attenuators are used in networking applications where an optical signal is too strong and needs to be reduced. There are many applications where this arises, such as needing to equalize the channel strength in a multi-wavelength system or reducing the signal level to meet the input specifications of an optical receiver. In both scenarios, reducing the optical signal strength is necessary or else system performance issues may arise.

If you are in the line of work where you are simulating networks using optical fiber, it is safe to assume that you have a few spools of bare fiber sitting in your test environment. The importance of ensuring your fiber-based network devices will work as envisioned before deployment in the field is vital. However, running simulations using unprotected or unsecured spools fiber can prevent you from producing the maximum results due to challenges that can arise.

The world’s financial communication networks are a paradigm of the modern world, and they operate at very high speeds through necessity, often using fiber optic technology. So fine are the lines between success and failure in today’s trading environment that just tiny fractions of seconds do matter. When financial institutions trade via these networks, shaving microseconds off network latency can result in a significant competitive advantage and millions of dollars annually. To reduce latency, one must understand the factors that can cause latency.

In the previous article, I briefly explained and compared two types of optical sources used in transmitters: LED and LD. Today, I am going to discuss what happens at the other end of a fiber link -- detectors. Optical detectors, as the name implied, can detect the amount of light received. Our very own eyes are a pair of detectors as they can receive light information with the retina and transmit that light data to our brain. In the visible light spectrum, our eyes are great detectors to inspect fiber break or light leakage. However, most fiber works in the invisible wavelength spectrum where human eyes won't be able to see. That is the where the optical detectors come in .

When talking about computers, latency is a word used to describe how long after you input a command that the results of that command are displayed on the screen. In technical terms, it’s the measured delay involved getting a datagram or packet from one hardware location to another and so obviously, the lower the latency, the better performing the device or network is.

Network optimization is pretty challenging and requires effort and expertise. However, as they say, the bitter the challenge, the sweeter the reward. Before you dive into it, do the right amount of research. Once you get the hang of it, the results will amaze you and, well, others!
