OPM4-FTTx PON Power Meter
The Noyes OPM4-FTTx from AFL Telecommunications is designed to measure optical
power in FTTH and other passive optical networks (PONs) that use 1490 nm for
downstream data and 1550 nm for downstream video traffic. In addition, the OPM4-FTTx
provides an integrated Visual Fault Locator (VFL) - 650 nm (red) laser for short-range fault
location and connectivity testing.
Equipped with wavelength filters and a dual photo detector, the OPM4-FTTx can separately
and simultaneously measure 1490 and 1550 nm power at the ONT or other points in
an FTTx PON. A large, dual-wavelength LCD display with backlight shows power at both
wavelengths in units of dBm or µW. The “set reference” feature may be used to measure
the difference between two power (dBm) levels, in units of dB measured at different parts
of the network.
The power meter and VFL ports accept Noyes thread-on style adapter caps and are
compatible with angled or non-angled connectors. The OPM4-FTTx offers an automatic
power shut-off feature, long battery life from standard AA alkaline batteries, and is fully
N.I.S.T. traceable.
