Handheld Optical Time-Domain Reflectometer

AV6416 Handheld Optical Time-Domain Reflectometer (AV6416 OTDR) is a test instrument designed for FTTx, which is mainly used to measure the physical characteristics of optical fiber & cables, including length, transmission loss and splice loss etc.. It can also accurately locate the event point and fault point along the optical fiber. AV6416 OTDR is widely applied to the engineering construction, maintenance test, and urgent repairing of optical fiber communication system, as well as the R&D, manufacturing, and test of optical fiber & cables. AV6416 OTDR adopts the most advanced technology of double color and two materials integrative mold design process, which makes it novel and beautiful in appearance, strong and firm in structure. With antireflection LCD display, the operation interface is quite clear even in field environment. Two power supply modes are available. With the large capacity lithium battery, the instrument can work more than 10 hours. It has two types of USB interfaces, which can connect to the U disk, or can communicate with PC through USB cable. In addition, it provides comfortable straps for convenient carrying.
