Digital Diagnostic Monitoring
2 wire serial bus address 1010001X (A2h) is used to access
measurement of transceiver temperature, internally mea-
sured supply voltage, TX bias current, TX optical output
power and RX optical input power which are shown in
Table 13. Each diagnostic parameter has a corresponding
high alarm, low alarm, high warning and low warning
threshold which are shown in Table 14. Alarm flags indi-
cate conditions likely to be associated with an inopera-

tional link and cause for immediate action. Warning flags
indicate conditions outside the normally guaranteed
bounds but not necessarily causes of immediate link fail-
ures. It is recommended that detection of an asserted flag
bit should be verified by a second read of the flag at least
100 msec later. The detail contents of the 2 wire address
A2h are shown in Table 15 to 21.
