Laser output disabled on T >2.0V or open, enabled on T <0.8V. DIS DIS 3. Should be pulled up with 4.7k 10kohms on host board to a voltage between 2.0V and 3.6V. MOD DEF(0) pulls line low to indicate module is plugged in. 4. For Rate Selectable version only: In accordance with SFF Committee SFF-8079 Draft Rev. 1.6, 5 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 1x, 2x, 4x Fibre Channel independent of rate select pin setting. 5. LOS is open collector output. Should be pulled up with 4.7k 10kohms on host board to a voltage between 2.0V and 3.6V. Logic 0 indicates normal operation logic 1 indicates loss of signal.
