Is the ability to manually set up tests and interpret Optical Time Domain Reflectometer (OTDR) traces becoming a lost art, due to embedded processors and sophisticated software? This article discusses some of the advanced OTDR techniques that expert technicians use to perform during testing. Similar to a digital photographer’s film camera experience, an understanding of the knowledge and skills used for manual OTDR testing can enhance a technician’s fiber testing when using the latest OTDR with automatic capabilities
Have you ever wondered how a Standard and an Application Note differ? No, the answer is not only that one is provided free by vendors. Both contain guidance and useful technical information so what is the difference? Well, a Standard is developed by many experts using consensus to provide accurate technical information and guidance while an Application Note, while technically accurate, is developed by one vendor to position their brand. One case in point is bi-directional testing using an OTDR. Many application notes have been written about bi-directional testing with an OTDR but what do the Standards say?

When we make an OTDR (Optical Time Domain Reflectometry) measurement, we use the launch cable to allow the trace to settle down after the pulse(s) are sent into the fiber, allowing us to see and analyse the start of the fiber being tested. This is because a large event will be seen in front of the connection on the trace usually caused by reflectance from the connector on the OTDR, thus not allowing us to make a good measurement of the first connection. The launch fiber also overcomes the issue of any dead zone (unseen event) that may occur if the pulse width is wider than the distance to a connector a short distance away from the OTDR connector.
By now you should know that an OTDR calculates signal loss based on the amount of reflected light, or backscatter, that it detects. Connection points along the fiber demonstrate a large reflection, which is used to determine the return loss of the connection. When there is a poor connection, light can bounce multiple times between events. Not only will light be reflected back towards the OTDR, it will also reflect in the opposite direction towards the far end, which is then reflected back again.

As fiber grows more common, network owners, network technicians and network installers are paying more attention to the two crucial devices for certifying fiber optical cable: the Optical Loss Test Set (OLTS) and the Optical Time Domain Reflectometer (OTDR). While the measurements taken by these instruments seem similar, they perform distinct yet important roles in the fiber certification process. This paper explains how each product works and how they complement each other to prevent network problems.
Akin to water flowing from a small pipe into a large pipe, gainers are essentially perceived increases in optical power that occur at splice points due to variations in fiber characteristics, including core diameter, numerical apertures, mode field diameters and backscatter coefficients. Since gainers can be a significant source of confusion for new optical time domain reflectometer (OTDR) users, let's take a look at why these occur, what impact they have and how to avoid them.
This primary international standard provides guidance for measurement of attenuation using power meters, light sources and OTDRs on 50/125 µm and 62.5 µm multimode fiber cabling that may include connectors, adapters and splices. Various test methods and cabling configurations are described. This report gives important information regarding upcoming changes for anyone needing to specify testing. Architects, Consultants and Engineers may use this information to learn of changes in IEC, anticipate customer concerns and gain insight to cabling testing trends.
Unlike required Tier 1 testing for attenuation (insertion loss), length and polarity that can be achieved with an optical loss test set (OLTs), few technicians in the field find themselves faced with Tier 2 testing and the need for an Optical Time Domain Reflectometer (OTDR). But every now and then, there is that one customer or consultant who specifies Tier 2 testing—especially as fiber networks have ever-tighter loss budgets and less room for error. Or there may be the need to gain more insight into the performance of a link component for troubleshooting purposes.
By now you will have heard about the new OptiFiber Pro OTDR and that’s a relief for me because I’ve been biting my tongue for a while! Now that its been announced, let me share my impressions and an overview of what makes the product unique. I will also include some links to more detailed information. Take this from a guy that has spent five of the last seven years playing with OTDRs… I’ve used them all. And this one is going to change everything!
Maximizing productivity in today's fast-paced workplace is essential. Whether installing new fiber links or troubleshooting an existing network, the faster you can locate a problem, the faster you can fix it. That's easier said than done when you are faced with a complex network of fibers, connectors and patch cords. A visual fault locator (VFL) is a great fiber diagnostic tool in your belt for verifying continuity and polarity and illuminating damaged connections, breaks, defective splices and tight fiber bends for exposed lengths of fiber in and around equipment racks. And while an Optical Time Domain Reflectometer (OTDR) is an indispensable tool for finding problems large or small along the entire cable length, it may be beyond the price range of someone who only occasionally needs to figure out where the fiber is broken.
