D.5.18.5 Current Tab
The Current tab allows you to assign performance monitoring thresholds for the wavelength converter
module laser current levels.
D.5.18.6 Power Tab
The Power tab allows you to assign performance monitoring thresholds for the wavelength converter
module Laser 1 power levels.
Bit Error Rate Sets the high threshold for the B1 bit error rate (BER) and the alarm severity level. The BER
is the ratio of received bits that contain errors.
FEC Counters
Errored Seconds Sets the high threshold for the number of FEC ES and the alarm severity level.
Severely Errored Seconds Sets the high threshold for the number of FEC SES and the alarm severity level.
Background Block Errors Sets the high threshold for the number of FEC BBE and the alarm severity level.
Unavailable Seconds Sets the high threshold for the number of FEC unavailable seconds (UAS) and the alarm
severity level. The detection of 10 consecutive SES begins a period of UAS. The 10 SES
detected are part of the UAS. The ES and SES counters decrement by 10 seconds and the
UAS counter increments by an equivalent number of seconds. A new period of available time
begins at the onset of 10 consecutive non-SES events.
Error Corrected Rate Sets the high threshold for the bit error corrected rate (ECR) and the alarm severity level. The
ECR is the ratio of FEC bit errors corrected to bits transmitted.
Uncorrected Codewords Rate Sets the high threshold for the uncorrected codeword rate (UCR) and the alarm severity level.
The UCR is the ratio of uncorrected codewords to codewords transmitted. A codeword is a
block of N symbols that carry K information symbols and R redundant symbols (N = K+R).
Unavailable Seconds Sets the high threshold for the number of B1 UAS and the alarm severity level. The detection
of 10 consecutive SES begins a period of UAS. The 10 SES detected are part of the UAS. The
ES and SES counters decrement by 10 seconds and the UAS counter increments by an
equivalent number of seconds. A new period of available time begins at the onset of 10
consecutive non-SES events.

Laser 1 Current
Value When the Update button is clicked, displays the Laser 1 current of the module.
Degrade Sets the degrade threshold for Laser 1 current (in mA) and the alarm severity level.
Fail Sets the failure threshold for Laser 1 current (in mA) and the alarm severity level.
