OLT 20A/B
OPTICAL LOSS TESTER
The OLT-20 series are multi-functional testing instruments for fiber optic networks.
The useful applications include installation,
routine inspection and daily maintenance
of MAN,WAN and CATV systems as well as
for lab test and research work.
The OLT-20 series integrate a laser source
module and a power meter module in one
set, which can perform power testing and
link loss testing of fiber optic network conveniently. It can test within the shortest
time and efficiently avoid errors caused by
not matching laser source and power meter. They are highly appreciated for their
excellent quality, safety, value and fast
testing features.
