LOF
LOF (Loss Of Frame)
A receive port on one of the optical cards has detected a Loss Of Frame. The LOF alarm
is raised if:
• the SONET framer detects framing errors in the A1/A2 overhead bytes as per the
SONET specification
• the OTN framer detects corruption in the Framing Alignment Signal (FAS) bytes.
This may be caused by the following reasons:
• A misconnected, damaged or dirty fiber
• The received power may not be within the acceptable range
• The data rate may be inconsistent
