l The PON board is in the normal state.
l The PON port is enabled.
Tools, Meters and Materials
l Single-mode fiber jumper with the SC/PC connector. No longer than 1 m. Best to use new
jumper.
l Burst optical power meter or ordinary optical power meter.
Impact on the System
When the transmit optical power of a PON port on the OLT is measured, the PON port will fail
to transmit any service.
Precautions
DANGER
Do not look into the optical port or the optical fiber connector without eye protection.
Before or after measuring the optical power, you need to clean the connector of the optical fiber.
This is because if a contaminated optical fiber is connected to a normal optical fiber connector,
the connector will be contaminated, which leads to abnormal attenuation and reflection and thus
affecting optical path quality.
Procedure
Step 1 Configuring the measure parameters of the optical power meter.
l Unit of optical power: dBm
l Wavelength: 1490 nm
Step 2 Connect the optical power meter directly to the optical module on the OLT PON port using
optical fiber jumper, as shown in Figure 1-45. The value on the optical power meter is the
transmit optical power of the OLT PON port.
