Product Description


This handheld fiber optic OTDR (optical time domain reflectometer) is an innovative test instrument for telecommunication networks and is specially designed for fiber network construction and maintenance in FTTx, WAN and CATV systems. It can be used in both single mode (1310/1550 nm) and multi mode (850/1300 nm) fiber applications. The unique hot key design makes it convenient and quick to conduct, review and analyze test results. The OTDR can save and transfer test results to a computer for further analysis, reporting and printing via included software. The OTDR is complete with adaptors for connection to different fiber types.
