FTR-1419 40km Extended GBIC Product Specification – November 2007
VII. Environmental Specifications
The GBIC Standard requires an ambient temperature range of 0°C to +50°C. Finisar
FTR-1419 GBICs have an extended range from 0°C to +70°C case temperature as
specified in Table 8.
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
Atmel AT24C01A 128 byte E
interfacing with the E
Wire Serial CMOS E
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 I
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 I
Test/Diagnostics Port.”
CAUTION: The microcontroller implements the Philips I
stretching. For details, consult the Philips I
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.
