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.

The Importance of Simulating PON Networks Before Deployment

Posted by John Kornegay on Fri, Jun 21, 2019 @ 12:06 PM

The fact that fiber optics are used in the transmission of light-signal data is widely known, as is the fact that separated ways are required to allow those signals to arrive at their intended destination. Typically speaking, there are two types of network that are employed to achieve this goal:

Eliminate the “Dead Zone” With an OTDR Launch Box

Posted by John Kornegay on Wed, Jan 23, 2019 @ 16:01 PM
The Optical Time Domain Reflectometer (OTDR) is a vital tool for fiber optic testing that can analyze the performance of fiber optic cabling through the use backscattering technologies, as well as identifying and locating connectors, splices, and breaks in fiber optic networks.

However, there is an unwanted phenomenon known as ‘dead zone’ that occurs when using an OTDR, which can cause improper readings if the right steps aren’t taken. This dead zone limitation can be avoided through the use of an OTDR Launch Box, which is what we review in more detail here.

The Launch Box Basics

The launch box, which is also known in the industry as a launch fiber, pulse suppressor, dead zone box or fiber ring, is a device that helps to eliminate the dead zone issue during fiber optic testing significantly. The dead zone is something that occurs when the pulse width changes and causes a high degree of reflection that can cover an area several hundred meters from where the OTDR is located. This results in the OTDR device not being able to detect events or issues in that area.

A term launch box is a box that contains a long spool of fiber that is placed in between the fiber being tested and the OTDR. This provides extra fiber on which the dead zone can occur. This enables the OTDR to now detect events at the beginning of the fiber being tested.

Using Your Launch Box

Launch boxes come in various shapes and sizes. However, all tend to have a robust outer casing to make them more durable. Each end of the fiber is terminated, with one to be attached to the OTDR and the other to the fiber being tested. Once connected to the relevant ports, the test can be run accordingly.

While using an OTDR box is a relatively simple process, you must be sure that it contains a sufficient length of fiber to take account of the entire dead zone or you still won’t achieve a proper reading on your trace and could miss events. Choosing the right OTDR launch box is important, as they can be customized to the specific application or device.

Choosing the Right One

When choosing the right OTDR launch box for your needs, you should approach it in the same way as you would choose a fiber patch cable. Box styles along with features such as connector type, fiber type, and fiber length should all be determined. Furthermore, some launch boxes are available with bulkhead adapters while others provide directly terminated fiber ends.

As mentioned before, a dead zone can cover several hundred meters, so your launch box spool should be long enough to cater for this. It is important to make sure you choose one that suits the job, and your OTDR user manual can provide guidance regarding the expected dead zones.

Reduce Truck Rolls With Fiber Monitoring

Posted by John Kornegay on Wed, Dec 19, 2018 @ 11:12 AM

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.

Using OMI to Benchmark CATV Systems

Posted by Kevin Miller on Wed, Oct 31, 2018 @ 12:10 PM

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.

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.
