Fiber Type Matters When Simulating Optical Links and Latency

Posted by Kevin Miller on Thu, Apr 2, 2020 @ 11:04 AM

Simulating real-world fiber optic links and time delays in the lab environment is both a frequent and necessary task for engineers performing R&D and equipment certification testing processes.  With the evolution to more advanced network architecture, increasing speeds of 400G and beyond, and latency always being a key element, replicating the field network as closely as possible in the lab is critical to ensure systems will perform as expected post-deployment.

Simulating Fiber Optic Links and Latency at Financial Institutions

Posted by Kevin Miller on Fri, Sep 13, 2019 @ 11:09 AM

For banking and financial companies in the digital age, having reliable and predictable connectivity to markets along with minimal latency is critical to their success.  A financial network backbone must ensure a customer’s access to funds, particularly after hours, while delivering an additional layer of security and visibility of the most up to date financial data.  But how can a bank or financial institution have confidence that their network will perform as expected?  The solution is to accurately simulate field links and latency in a lab environment to validate system performance will be at the high level it needs to be.

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.
