GPON System Parameters

About GPON System Parameters

The PON system parameters allow you to to configure and manage the PON system.

GPON System Optical Parameter Detection (SFP)

GPON System Optical Parameter Detection provides information about optical parameter diagnosis and the GPON port optical parameter threshold. It is mainly used to query the alarm monitoring of GPON optical module parameters and optical module parameters in real time. When the optical line problem occurs in the GPON system, these functions can be used to confirm whether the GPON optical module works normally.

GPON Port Optical Threshold Alarm

GPON Port Optical Threshold Alarm allows you to configure the GPON port to receive and send optical parameter alarm thresholds. When the receiving and transmitting optical power of the GPON optical module is not within the threshold, an optical power alarm will be generated.

GPON Uplink FEC

By configuring the GPON Uplink FEC function, FEC is performed on data frames to increase the reliability of data transmission.

Optical link protection (not supported yet)

The optical line protection system is an automatic monitoring and protection system that is completely independent of the communication transmission system and is completely established on the physical link of the optical cable. When the working optical fiber loss increases and the communication quality is degraded or the working optical fiber is blocked, the system can automatically switch the optical communication transmission system from the working optical fiber to the standby optical fiber in real time, restore communication, and realize synchronous switching protection of the optical cable line, thereby greatly improving The availability of fiber optic cable lines enhances the reliability of communication systems and guarantees service quality.

How to Configure GPON System Parameters

Configuring GPON Uplink FEC

To configure GPON uplink FEC, perform this procedure.

Before you begin

Modifying and activating the line profile entry will cause the ONT that is associated with the profile offline and online.

active

Example:

Device(deploy-profile-line-5)# active

Activates the rule.
