Why Do You Need OTDR Launch Box?

Why Do You Need OTDR Launch Box? Optical time domain reflectometer (OTDR) is a necessary fiber optic testing tool which use light backscattering technologies to analyze the optical fiber performance. It can test the light loss and locate the breaks, splices and connectors in fiber optic network. However, OTDR has "dead zone" which can affect the testing result if proper measure is not taken. To overcome the limitation of OTDR dead zone, OTDR...

Test Optical Splitters Loss With Optical Power Meter & Light Source

Test Optical Splitters Loss With Optical Power Meter & Light Source Optical splitters are usually used in passive optical networks (PONs) to distribute fiber to individual homes or businesses. There is something different between testing an optical splitter and a patch cable although both of them use optical power meter and light source to test. In this tutorial, we are going to talk about optical splitter loss testing with optical power meter a...

OTDR (Optical Time Domain Reflectometer) Dead Zone Tutorial

OTDR (Optical Time Domain Reflectometer) Dead Zone Tutorial OTDR (Optical Time Domain Reflectometer) is a familiar fiber test instrument for technicians or installers to characterize an optical fiber. To understand the specifications which may affect the performance of OTDR can help users get maximum performance from their OTDRs. This tutorial will introduce one of the key specifications—Dead Zone. What Is Dead Zone The OTDR dead zon...

Optical Time-Domain Reflectometer Tutorial

Optical Time-Domain Reflectometer Tutorial What Is ODTR? Optical Time-Domain Reflectometer (OTDR) is an optoelectronic instrument used to characterize an optical fiber. It can be considered as the optical equivalent of an electronic time-domain reflectometer. OTDR injects a series of optical pulses into the fiber under test. It also extracts, from the same end of the fiber,light that is scattered or reflected back from points along the fib...

How to Solve the Common Problems in OTDR Testing

How to Solve the Common Problems in OTDR Testing OTDR (Optical Time Domain Reflectometer) is widely used in all phases of a fiber system's life, from construction to maintenance to fault locating and restoration. However, even a trained and experienced OTDR operator may have difficulty interpreting a fiber trace at times. There are a few cases where it is almost impossible to get an exact distance or loss determination based on one measurement. In...

Visual Fault Locator Tutorial

Visual Fault Locator Tutorial What Is Visual Fault Locator? Visual Fault Locator (identifier), or VFL/VFI, is a visible red laser designed to inject visible light energy into an optical fiber. Sharp bends, breaks, faulty connectors and other faults will "leak" red light allowing technicians to visually spot the defects. Fiber visual fault locator, also called laser fault locator, is a device which is able to locate the breakpoint...
