Notes: 1. Circuit ground is internally isolated from chassis ground. 2. Laser output disabled on TDIS >2.0V or open, enabled on TDIS <0.8V. 3. Should be pulled up with 4.7k - 10 kohms 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. Specific information when selecting line rate: Rate selection is done 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-84726 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 - 10 kohms on host board to a voltage between 2.0V and 3.6V. Logic 0 indicates normal operation; logic 1 indicates loss of signal.

VIII. Digital Diagnostic Functions All Finisar SFPs support the 2-wire serial communication protocol outlined in the SFP MSA6. These SFPs use an Atmel AT24C01A 128 byte E2PROM with an address of A0h (see table below for E2PROM contents). For details on interfacing with the E2PROM, see the Atmel data sheet titled "AT24C01A/02/04/08/16 2-Wire Serial CMOS E2PROM."7 Finisar's CWDM SFPs also support extended diagnostic features as described in Finisar Applications Note AN-2030, "Digital Diagnostic Monitoring Interface for Optical Transceivers"8, and additional information is available in SFF standard titled: "Digital Diagnostic Monitoring Interface for Optical Transceivers9 (SFF-8472 rev9.3). A controller IC that monitors system parameters such as laser current, module temperature, transmitter power, and received power is accessible at address A2H. I2C clock speed, digital diagnostic accuracy and digital diagnostic range can be found in the table below. Values in the table represent the worst-case values over temperature, voltage, and life.
