5.4 Transceiver
Click Maintenance > System > Transceiver to view your GPON Device’s current transceiver
status and configure alarm thresholds. The optical SFP transceiver’s support for the Digital
Diagnostics Monitoring Interface (DDMI) function lets you monitor the transceiver’s parameters to
perform component monitoring, fault isolation and failure prediction tasks. This allows proactive,
preventative network maintenance to help ensure service continuity. The values in the following
figure are an example for reference only. See the table for details about the normal parameter
ranges.

Each field is described in the following table.
Administrator
Inactivity Timer
Type how many minutes a management session (either via the Web Configurator or
telnet) can be left idle before the session times out. The default is 5 minutes. After it
times out you have to log in with your password again. Very long idle timeouts may have
security risks. A value of "0" means a management session never times out, no matter
how long it has been left idle (not recommended).
Password
Old Password
Type the default password or the existing password you use to access the system in this
field.
New Password
Type your new system password (up to 30 characters). Note that as you type a password,
the screen displays a (*) for each character you type. After you change the password, use
the new password to access the GPON Device.
Retype to Confirm Type the new password again for confirmation.
Apply
Click Apply to save your changes back to the GPON Device.
Cancel
Click Cancel to begin configuring this screen afresh.
