MOD_DEF(0) pulls line low to indicate module is plugged in. For Rate Selectable Version Only: In accordance with SFF Committee SFF-8079 Draft, Rev.1.6, Table 3. Note that rate select can also be set through 2-wire bus in accordance with SFF-8472 at Bit 3, Byte 110, Address A2h (note: writing ‘1’ selects full bandwidth operation). Rate select is the logic OR of the input state of Rate Select Pin and 2-wire bus. Non Rate Selectable version can operate at 1G, 2G, 4G Fibre Channel independent of rate select pin setting. LOS is open collector output. Should be pulled up with 4.7 k – 10 kohms on host board to a voltage between 2.0 V and 3.6 V. Logic 0 indicates normal operation; logic 1 indicates loss of signal.
