Procedure

Step 1

Check whether the OPTICAL interface on the ONT rear panel is connected to the optical fiber

properly.

Step 2

Check whether the GPON ONT fails to register with the OLT. If such a problem occurs, contact

the service provider for help.

6.3.4 LAN LED Off

This topic describes how to locate the fault when the LAN LED does not illuminate.

Procedure

Step 1

Check whether the network cables match the device.

Step 2

Check whether the network cables are properly connected.

Step 3

Check whether the LED of the network interface card (NIC) is normal.

If the LINK LED is always on, it indicates that the network cables are properly connected. If

the ACT LED blinks, it indicates that data is being transmitted.

Step 4

Check whether the NIC works in the normal state.

In

Device Manager

of the Windows operating system, check whether there is a device marked

with

?

or

!

under

Network Adapter

. If there is a device marked with

?

or

!

under

Network

Adapter

, uninstall the NIC and then re-install it, or install the NIC in another slot. If the problem

persists, replace the NIC.

Procedure

Step 1

Contact the service provider to check whether the CATV service is provisioned.

Step 2

Check whether the optical fiber is properly connected.

Step 3

Measure the optical power of the downstream 1550 nm wavelength by using an optical power

meter. Check whether the measured optical power complies with the optical specifications of

optical ports on GPON ONTs as specified in

6.2.2 Optical Power Meter

.

l

If the measured optical power complies with the specifications, proceed to the next step.

l

If the measured optical power does not comply with the specifications, check whether the

endface of the optical fiber connected to the ONT is contaminated. If it is contaminated, wipe

the endface of the optical fiber in a unidirectional manner with paper that is specially used

for cleaning optical fibers or lens of cameras.

Step 4

Check whether the combiner works in the normal state.
