GAOTek offers a wide range of Optical Time Domain Reflectometers (OTDRs) and locators, which consist of an array of products, for example, OTDRs, OTDR with visual-fault- locators (VFL), fault locators, optical fiber identifiers, and optical fiber rangers. All of them are essentially used to verify the installations of fibers and to detect faults and malfunctions in those fiber optic systems.

Functions of OTDR and Locators

Optical Time Domain Reflectometers (OTDRs) are essential devices for the execution of new fiber optic installations and compare issues associated with the existing fiber links. A sophisticated version of OTDR testers is the Visual Fault Locators (VFL) which helps in detecting fiber communication networks. They are mostly utilized to authorize new fiber installations, examine fibers, and detect flaws within the fiber optic networks.

The main functions of Visual Fault Locators (VFL) are fiber tracking and consistently monitoring the optical systems during and after installations. Optical Visual Fault Locators are powerful enough to find deficiencies in fibers, run end-to-end consistency tests, and execute fiber tracking and for check-ups.

Optical Fiber Identifiers are reliable devices due to their effectiveness to detect the presence of signals on optical fibers. Another important characteristic of these devices is that they guarantee the connection of live fibers while also being capable of tracking fibers from end to end. Optical Fiber Rangers can control damages on optical fiber links, and are used for maintenance and test. Similarly, many technical specialists use these devices to fix, control and maintain optical fibers.


The OTDRs and Locators supplied by GAOTek are convenient and reliable test tools. A majority of the devices have durable batteries which can last long hours. These devices are built to implement and comply with the OTDR technical standards. These high-quality devices are precisely designed to detect fiber defects and they have an auto test, manual test, dead zone and real-time test mode.

Applications and Industries

The OTDRs and Locators produced by GAOTek include numerous functions that involve fiber optics engineering, commissioning, and technical support. Likewise, these devices are convenient for several sectors such as aviation and defense, electric utility, hardware assembling, mining, oil and gas as well as logistics. Also, they are mostly used by installers and contractual workers. LAN, FDDI, and ATM are some of the visual frameworks where OTDRs and Locators are utilized in order to support the fiber optic systems.
