The key features：
TFT true color display, touch screen operation
Graphical interface, one interface can display all measurement results
Dual-port design for pass through mode, support online monitoring and termination measurement
Provide ten groups of threshold selection, pass/alarming/fail, three indicators are correspondent with tested optical line status
Power values adapt green/yellow/red to distinguish pass/alarming/fail status
Built-in 500 records and upload via USB port
Built-in large capacity Li-ion battery, ultra long operation time
Product overview
With the rapid development of optical network, there is a need of PON Power Meter to judge the transmission quality of optical link during the opening and maintenance of operators EPON/GPON services.
OFT-1120A is a portable tester specially designed for FTTx/PON passive optical network testing, which can be connected to OLT and ONT so as to realize online synchronous measurement and display of optical signal. It is a helpful assistant for PON network engineer technicians for field testing.
Typical applications
Make an easy evaluation for optical power in any place of whole network from OLT to ONT
.bmp)
l FTTx/PON deployment：during opening phase, measure all PON signal, verify and ensure to meet network standards；
l FTTx/PON maintenance：various transportation problems in daily maintenance, for example, contaminated end face, fiber macro bending and fracture, optical transceivers fault etc.
