VI. Wavelength Stabilization The laser transmitter will not be turned on until its temperature is adjusted to ensure operation within the specified channel (X +/- 0.4nm). This temperature stabilization time is dependent on the ambient temperature conditions, but will typically occur within 30 seconds of powering the GBIC (90 seconds maximum). The device will transmit within the specified wavelength tolerance (X +/- 0.1nm) within 5 seconds of transmitter operation.

IX. Serial Communication Protocol All Finisar optical GBICs implement serial identification features described for `Module Definition "4"' as outlined in Annex D of the GBIC Specification 1 . These GBICs use an Atmel AT24C01A 128 byte E2 PROM at address A0H. For details on interfacing with the E2 PROM, see the Atmel data sheet titled "AT24C01A/02/04/08/16 2-Wire Serial CMOS E2 PROM."3 Finisar's DWDM GBICs also support extended diagnostic features as described in Finisar Applications Note AN-2030, "Digital Diagnostic Monitoring Interface for Optical Transceivers"2 . A controller IC that monitors system parameters such as laser current, module temperature, transmitter power, and received power is accessible at address A2H.
