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.

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

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.

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.

Verification testing answers this question. For copper cabling, these simple-to-use, low cost tools perform basic continuity functions such as wire map and toning. Wire mapping will tell you that each pair is connected to the right pins at plugs and jacks with good contacts in the terminations, while toning is used to help identify a specific cable in a bundle or at the remote end. Some verification testers like Fluke Networks' MicroScanner2 Cable Verifier include a Time Domain Reflectometer (TDR) feature to help determine the distance to the end of a cable or a trouble spot. It can also detect if a switch is connected to the cable under test. 

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.
