GAO Tek Releases New Optical Device: Hand held OTDR

Toronto, Canada (SANEPR.com) June 23, 2008 -- With high memory capacity for testing data, the GAO3620 OTDR is capable of performing multiple calculations such as length, attenuation coefficient, connection point, fault point and loss distribution curves of the fiber. The optical device performs tasks such as loss characteristics analysis and fault point searching. It also shows the loss between two points, splice loss and return loss. Even though this OTDR has numerous features and functions it remains small in size, is easy to use and is designed to be highly durable even for outdoor operations. It is being widely used today in fiber manufacture, installation and maintenance. GAO’s hand-held OTDR is compatible with CATV, ISP and Telecommunications Fiber Networks.
