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 2-
Wire 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
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-20304.
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.
