optical ports
•
OLT:
optical connector port input which measures 1490 nm downstream power levels and
optional 1550 nm (RF Video) in a GPON network. On FX81, measures 1577 nm downstream
power levels for XGS-PON/10G-EPON.
•
ONT:
optical connector port input which measures 1310 nm upstream power level. On FX81,
measures the 1270 nm upstream power levels for XGS-PON/10G-EPON.
•
OPM
(optional)
:
Measures optical power in absolute and relative mode and to save the
measurement results.
•
VFL
(optional)
:
Use the 650 nm visual fault locator to visually locate breaks or excessive
bends in fibers.
[FX80 Only]
The FX80 can be configured with either optional OPM or VFL, but not both. The
FX81 can only be configured with optional BB-OPM with 4 wavelengths.
4.2.2 Service Port
The service port (micro-USB) located on the left side of the device is used for battery charging
and transferring OPM results to the LTSync and/or FMOLTS software application. An OTG cable
may be needed for operations with an Android mobile device.
