The BER increase that causes the condition is sometimes caused by a physical fiber problem such as a poor
fiber connection, a bend in the fiber that exceeds the permitted bend radius, or a bad fiber splice.
The SD clears when the BER level falls to one-tenth of the threshold level that triggered the alarm.

SDBER-EXCEED-HO
Default Severity: Not Alarmed (NA), Non-Service-Affecting (NSA)
Logical Object: VCMON-HP, VCTRM-HP
The Signal Degrade Threshold Exceeded for High Order condition indicates that the signal degrade BER
threshold has been exceeded for a high-order (VC-4) path on optical (traffic) cards. SDBER-EXCEED-HO
occurs when the signal BER falls within the degrade threshold (typically 1E-7 dBm) set on the node.
Class 1 laser product.
Statement 1008
Warning
Class 1M laser radiation when open. Do not view directly with optical instruments.
Statement 1053
Warning
Invisible laser radiation could be emitted from the end of the unterminated fiber cable or connector.
Do not stare into the beam directly with optical instruments. Viewing the laser output with certain
optical instruments (for example, eye loupes, magnifiers, and microscopes) within a distance of 100 mm
could pose an eye hazard.
