plugged. See “Table 3: Signal Definitions” in the GBIC Specification Revision 5.41
for a description of the functions of each pin listed above.
II.
Electrical Power Interface
Finisar FTR-1419 GBICs have an extended power supply voltage range of 3.15V to 5.5V
as described in Table 2. They are compatible with both 5V and 3.3V systems. The GBIC
specification calls for a range of only 4.75V to 5.25 volts. The 6V maximum voltage is
not allowed for continuous operation, however, TX_FAULT and TX_DISABLE circuitry
in Finisar GBICs will function at 6V.

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. If host_Vcc is 3.3V, then they must be pulled to 3.3V. If
host_Vcc is 3.3V, do not pull the MOD_DEF pins to 5V. For more detailed information,
see sections 5.3.1 – 5.3.8 in the GBIC Specification Rev. 5.41.

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 E2PROM (with an address of 1010000X). For details on
interfacing with the E2PROM, see the Atmel data sheet titled “AT24C01A/02/04/08/16 2Wire Serial CMOS E2PROM.”5
All Finisar optical GBICs also incorporate a microcontroller that monitors system
parameters such as laser current, laser temperature, and, in the case of 1300nm/1550nm
parts, transmitted power. The microcontroller I2C address is 1010111X, so it won’t
conflict with the AT24C01A. For a complete description of how to use Finisar’s extended
features, see Finisar’s Application Note AN-2025: “Using the Finisar GBIC I2C
Test/Diagnostics Port.”4
CAUTION: The microcontroller implements the Philips I2C protocol including clock
stretching. For details, consult the Philips I2C-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.
