OLP-88
Through path
The through path links the ONT upstream (1310 nm) and OLT
downstream (1490 nm and 1550 nm) signals. Thanks to the low
insertion loss the OLP-88 can be inserted into the PON network
transparently.
Burst power measurements at 1310 nm
The OLP-88 can also be used to measure burst type signals as
found in PON uplink paths at 1310 nm. The average burst power
is displayed independently from the burst duty cycle (active/
idle). This power meter port is calibrated at the respective center
wavelength.
