Low RX Power Alarm Begin and Clear
An SFP module has the ability to monitor and trigger an alarm on a high or low RX laser power reading.
This ability is internal to the SFP and is part of the digital diagnostic interface common to many SFPs. This
notification is sent when bit 6 of byte 113 in the real-time diagnostic registers changes from 0 to 1 (Begin) or
from a 1 to a 0 (Clear).
This bit is set when the SFP received laser power falls below the low power alarm level. The SFP RX power
value is stored at bytes 104 & 105 of the SFP diagnostic register table.
