Optical Time Domain Reflectometer (OTDR) for Fiber Optic Testing - Singlemode 80-100km
OTDRs (Optical Time Domain Reflectometer) are used to measure fiber length and overall optical attenuation within a circuit. It also measures total insertion loss, including splices and mated connectors. In addition, it can be used to locate faults or broken fibers (micro bends) in the cable routing.
Another benefit is its ability to act as a multifunctional test instrument with high performance design for FTTx networks. It features two types of operation: touchscreen and keypress, making it both convenient and easy to use. The advanced LCD touchscreen is easily visible outdoors thanks to its anti-glare technology.
This OTDR features four optical ports and integrates an optical power meter and visual fault locator (VFL), supporting both singlemode and multimode testing. The interchangeable port configurations provide added versatility for testing and inspecting optical fiber connections.
The Optical Time Domain Reflectometer has an abundant number of external ports. You can externally connect USB and printers, allowing data communication with PCs. Test results can be stored internally. It makes use of a large capacity lithium battery, allowing up to 8 hours of use, making it suitable for extended outdoor work.
