SM OTDR OTA-240T 1310 /1550 /1625 nm

Oxin OTA series Optical Time Domain Reflectometer (OTDR) is the new generation of intelligent meter for the detection of fiber communications systems. With the popularize of optical network construction in cities and country sides, the measurement of optical network became short and disperse, OTA is specially designed for that kind of application, its economic and also have outstanding performance. OTA is manufactured with patience and carefulness, following the national standards to combine the rich experience and modern technology, subject to stringent mechanical, electronic and optical testing, quality assurance, in the other way, new design makes OTA smarter and more compact and multi-purpose, also it has various functions.
