The JDSU OLP-3057 FTTX Optical SIM adds high performance, optical power
meter testing to the HST-3000 for testing, installing, and maintaining
FTTX/PON-based systems. Its through mode allows simultaneous measurement
at all three wavelengths on the fiber: 1490 nm and 1550 nm downstream, as well
as the 1310 nm upstream. The 1310 nm channel provides correct power measurements of burst type upstream PON signals.
