Additional InformationPortable Structure Design
OTDR Tests:Â GAO-OTDR-114 Series Handheld OTDR Test Set supports comprehensive fiber test functions and generates the test result with higher accuracy and higher speed. It can be the top option for Optical Fibre Network installation; operation; and maintenance.
iOTA – Intelligent Optical Link Topology Analysis:
Traditional OTDR only can display loss and event list of the fiber link. Event types and link topology requires an experienced engineer to analyze manually. However, the rapid growth of FTTH deployment demand definitely increases the engineer’s workload and the operator’s labor cost. iOTA function of GAO-OTDR-114 provides a more comprehensive analysis of fiber link, assists engineer to deploy, operate, and maintain optical fiber network more easily.
iOTA Test Principles: iOTA intelligently combines different pulse widths, only needs one time and one button can get the loss and return loss of fiber and splitter. Multiple pulse acquisition and algorithm can deliver more detail information of every element of the fiber link.
iNET – Intelligent Network Test Tool
Traditional OTDR only can determine the defects occurred in physical optical fibers. However, during the installation and maintenance of FTTH, it always requires to determine the defects which occurred in the data layer. The iNET function of GAO-OTDR-114 integrates common Ethernet testing methods, such as Ping, Traceroute, FTP, and HTTP; can verify Ethernet performance with high efficiency and reduce operation cost greatly.
