Benefits of Using Fiber Optic Attenuators with Doped Fiber

Posted by John Kornegay on Thu, Oct 18, 2018 @ 12:10 PM

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.

Four Benefits of Protecting Your Optical Fiber In A Test Environment

Posted by John Kornegay on Mon, Sep 10, 2018 @ 15:09 PM

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.

Sources of Latency in a Financial Communications Network

Posted by John Kornegay on Tue, Aug 14, 2018 @ 10:08 AM

 

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.

Why Is Latency So Important In Financial Networks?

Posted by John Kornegay on Tue, Jul 10, 2018 @ 12:07 PM

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.
