Table 2. Electrical power interface Note 1: Receiver sensitivity is compliant with power supply sinusoidal modulation of 20 Hz to 1.5 MHz 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 VI, "Serial Communication Protocol"). Both MOD_DEF(1) and MOD_DEF(2) must be pulled up to host_Vcc. Note - MOD_DEF(0) is grounded inside the GBIC to indicate the correct mode of operation. For more detailed information, see sections 5.3.1 - 5.3.8 in the GBIC Specification Rev. 5.41 .

Note 1: The Transmitter Center Wavelength "x" is as specified by the customer. The current available wavelengths are: 1470, 1490, 1510, 1530, 1550, 1570, 1590, and 1610 nm. Please see the "Product Selection" section on page 2. Note 2: Parameters are specified over temperature and at end of life unless otherwise noted. Note 3: All parameters are measured on a Finisar GBIC Evaluation Card unless otherwise noted. Note 4: To convert from dB to kilometers, use 0.3 dB/km. For example, a link budget of 7dB equals 7dB/0.3dB/km = 23.3km. Add 0.5dB additional loss per connector. Note 5: Jitter added by receiver.

VIII. Serial Communication Protocol All Finisar optical GBICs are `Module Definition "4"' and support the 2 wire serial communication protocol outlined in the GBIC Specification 1 . These GBICs use an Atmel AT24C01A 128 byte E2 PROM (with an address of 1010000X). For details on interfacing with the E2 PROM, see the Atmel data sheet titled "AT24C01A/02/04/08/16 2Wire Serial CMOS E2 PROM."5 All Finisar optical GBICs also incorporate a microcontroller that monitors system parameters such as laser current, laser temperature, and, in the case of 13xx/14xx/15xx/16xx nm parts, transmitted power. For a complete description of how to use Finisar's extended features, see Finisar's Application Note AN-2030: "Digital Diagnostic Monitoring Interface for SFP Optical Transceivers."4
CAUTION: The microcontroller implements the Philips I2 C protocol including clock stretching. For details, consult the Philips I2 C-Bus Specification. Clock stretching allows a fast master to communicate with a slow slave device, and it requires that the host monitor the clock line every time it releases the line high. If a host does not implement clock stretching (drives the bus blind), it must run the clock below 8kHz, so that Finisar's microcontroller has time to process instructions. If clock stretching is supported, the clock may be run at up to 100kHz.
