Table 2. Electrical power interface Note 1: Receiver sensitivity is compliant with power supply sinusoidal of 20 Hz to 1.5Mhz up to specified value applied through the recommended power supply filtering network
III. Low Speed Signals RX_LOS, TX_DISABLE, and TX_FAULT are TTL signals as described in Table 3. MOD_DEF(1) (SCL) and MOD_DEF(2) (SDA) are open drain CMOS signals (see section VIII, "Serial Communication Protocol"). Both MOD_DEF(1) and MOD_DEF(2) must be pulled up to host_Vcc. For more detailed information, see sections 5.3.1 - 5.3.8 in the GBIC Specification Revision 5.53.

VIII. Serial Communication Protocol All Finisar optical GBICs implement serial identification features described for `Module Definition "4"' as outlined in Annex D of the GBIC Specification3. These GBICs use an Atmel AT24C01A 128 byte E2PROM at address A0H. 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 GBICs also support extended diagnostic features as described in Finisar Applications Note AN-2030, "Digital Diagnostic Monitoring Interface for Optical Transceivers"6. A controller IC that monitors system parameters such as laser current, module temperature, transmitter power, and received power is accessible at address A2H.
