by 0x2e112004 The signal fail of ONTi (SFi) occurs
Today i will discuss about 0x2e112004 The signal fail of ONTi (SFi) occurs alarm. System generates this alarm when a GPON port detects that the signals of an ONT fail and that the BER check error code rate in the upstream direction of the ONT reaches the threshold.

Attribute:
| Alarm ID | Alarm Severity | Alarm Type |
|---|---|---|
| 0x2e112004 | Warning | Fault |
Impact on the System:
The data link is interrupted and the data cannot be transmitted in the normal state. The services of the ONT are interrupted.
Possible Causes:
- The optical fiber is faulty.
- The ONT is abnormal.
Procedure:
- Check the optical fiber.
- If the optical fiber is not connected properly, reconnect the optical fiber again to ensure that the optical fiber is connected correctly and securely.
- If the optical fiber is aged, bent, or damaged, replace the optical fiber.
- If the connector of the optical fiber is not clean, clean the optical fiber.
- If the ONT is abnormal, reset or replace the ONT.

The bit error ratio (BER) domain is a domain of eight bits. It is used to calculate the parity check value of a segment of bytes. The receiver calculates a parity check value and compares the calculated value with the received BER value to obtain the number of error codes on the link.
