port. Conditions that can cause an SSFODU are:
• LOS-P (Loss of Signal – OTU)
• LOF (Loss of Frame – OTU)

• ODU-AIS
These conditions may be caused by the following reasons:
• A misconnected, damaged or dirty fiber on the trail between the local OTUk receive
port and the far end transmitter
• OTS/OMS layer failure on the OCh trail
• The received power may not be within the acceptable range on the Far end input
