Overview
The NF-912 PON optical power meter is designed through a specially designed
optical path and electricity.-Path structure to realize the special
requirements of signal optical power measurement in the PON system. In other
words, it is necessary to meet the simultaneous test and online measurement of
three kinds of optical signal wavelengths on the line. With the burst test
function of testing and 1310nm signals, Thus it is convenient to install,
manage and maintain the PON system.

Scope of application
At present, FTTx/PON (fiber to home, fiber to building, fiber to resident,
etc.) network construction is becoming a hot spot in the construction of
global access networks. The power meter is suitable for measuring optical
fiber-to-home networks. The specific measurement power meter outputs three
kinds of wavelength laser (1310nm 1490nm 1550nm) from a single port, in which
1330nm measures the uplink transmission direction, 1490 and 1550 can measure
the downlink direction test.
- 0NT Uplink signal probe (1310nm)
- OLTNideo Downlink signal probe (1490/1550nm)

Battery charging
When the power icon in the upper right corner of the host screen appears low
power or does not boot properly, it is usually caused by insufficient battery
voltage and needs to be plugged in a power adapter to charge the battery.
Matters needing attention
-
Do not push too hard in the operation of the optical fiber SC interface, insert or unplug the interface into or out of the SC single flange of the main engine, should plug and pull smoothly
-
After the instrument test, please turn it off in time so as not to affect the battery life
-
Do not open the rear cover of the main engine on your own, need to be repaired or calibrated on time, please send it back to the production plant or agent.
