Whether the RI port sensitivity of the PID board can be queried

2

The module of the RI port on the PID board is a passive red/blue band filter. The RI port is only a logical optical port connected to an optical fiber. The receive wavelengths (12+8) on the RI port are processed by the red/blue band filter, and then arrive on the 12 independent physical optical ports of a blue-band PID board and the 8 independent physical optical ports of a red-band PID board.
TO/RI, T01/R01, and T02/R02 ports are only logical optical ports for fiber connections. For logical optical ports, the sensitivity indicator is unnecessary. Therefore, the transmit/receive optical power reported by such boards are only logically calculated values.

Whether the TO/RI ports on NPO2E boards have requirements for optical power
The TO/RI ports on NPO2E boards are connected to filters and therefore they have no requirements for optical power.

PID
The photonics integrated device (PID) feature integrates conventional optical conversion units and MUX/DEMUX units into a PID board. It achieves high integration.

Whether the VI port on the OBU board can report a LOS alarm
No, the VI port on the OBU board cannot report a LOS alarm. When logical fibers are created on the NMS, if no FIU board is configured at the local site and the multiplexed-wavelength optical signals of the peer site need to be connected to the OBU board at the local site, you are advised to connect the logical fiber to the IN port of the OBU board. In this way, the corresponding logical fiber will turn red in case of a fiber cut.
