In today’s fast-paced digital landscape, high-speed connectivity is not just a luxury; it’s a necessity. With the increasing demand for faster and more reliable network services, service providers and fiber infrastructure providers are increasingly turning to remote fiber test systems (RFTS) to guarantee fiber infrastructure availability, reduce fiber network outages, and improve service delivery. These […]

First off, what is loopback OTDR testing? The concept is simple: it involves using a single OTDR, which stays at one site, and testing two fibers at the same time by using a loopback fiber or loopback device at the other site. And of course when it comes to OTDR testing you have the […]
One of the challenges with bi-directional (bi-dir) OTDR testing is the logistics and the amount of affordable, available, or required test equipment. A single-unit approach is usually considered to try and save on cost—one piece of test equipment versus two and one tech versus two—but it has its drawbacks. For one, it does not verify […]
Are your standards high enough to ensure quality fiber builds? In the previous blog we saw that bi-directional (bi-dir) OTDR testing provides a number of advantages and lets you deal with issues arising from differences between fibers being spliced together (specifically difference in Modal Field Diameter – MFD) that result in false positives or false […]
Well, let’s start with why test at all? With all the time, effort, and money (particularly the money) put into the deployment of dark fiber or construction of fiber networks, owners and investors want to make sure they are getting good quality fiber links out of these projects. Everyone knows that some form of testing […]
One of the most significant areas we have seen driving new test and measurement requirements has been data center interconnect – DCI. This rapidly growing area leverages the emergence of pluggable coherent optics (DCO) to allow rapid scaling of data center interconnect bandwidth based on an open, multi-vendor ecosystem. For the DCI market to grow […]
With the emergence of 400G Ethernet we have seen the wide deployment of higher order modulation in client interfaces. We have moved from the mature NRZ of 100G and below to PAM-4 modulation both optically and electrically. This has allowed 400G links to be deployed for reaches of 10km. But what about applications like data […]
