TW-7E PON optical power meter is a special tester to test FTTx/PON passive optical network, it can synchronously measure voice, data and video signal on BPON/EPON/GPON framework. It also can set the power threshold and indicate the pass, alarm and fail of every wavelengh.  

◆  Feature
Test power value of 1490nm, 1550nm and 1310nm in PON system at the same time.
Test burst mode of 1310nm up wavelength.
Dual-port and pass-through design, it guarantee communication from OLT to ONT during test. 
Ten groups threshold can be selected, three indicator display the optical path state.
English menu.
USB interface.
Store 500 records on tester and the records can be viewed and deleted.
It can be set threshold, upload data and calibrate wavelength.
It can be set from 5 to 99 seconds to power off automatically.

◆     Application

FTTx/PON open: test all PON signal during openning to prove that match the network standard.
FTTx/PON maintenance: test the transmission performance in daily maintenance.

It can easily evaluate power value of any position in network which is from OLT to ONT.
