OLP-87/OLP-87P 9
OLP-87/OLP-87P POWER METERS
1 INTRODUCTION
Broadband mode
The 1310/1490 nm instruments feature non-selective power
measurements via the OLT port. In this mode, the OLP-87/OLP-
87P FTTx tester behaves like a standard broadband power meter,
e.g. attenuation measurements can be made in the usual way
using a suitable optical source. OLS-85 Optical Light Sources are
ideal for this application.
Both modulated and unmodulated light signals can be
measured. The average power of modulated light signals is
displayed. The broadband power meter is calibrated at 1310 nm,
1490 nm, 1550 nm and 1625 nm. Modulated signal mode, which
uses different fixed frequencies, can be used to identify fibers in
a fiber bundle, for example.
The “Auto-” function allows automatic wavelength detection.
This application requires a wavelength encoding light source,
e.g. one of the OLS-85 Optical Light Sources.
