Finisar Corporation Page 6 June 2009 Rev E2 Finisar FWLF-1631-xx DWDM SFP - June 2009 VI. Wavelength Stabilization The laser transmitter will not be turned on until its temperature is adjusted to ensure operation within the specified channel (X +/- 300pm). This temperature stabilization time is dependent on the ambient temperature conditions, but will typically occur within 5 seconds of powering the device. The module will transmit within the specified wavelength tolerance (X +/- 100pm) within 10 ms of transmitter operation. VII.

Finisar Corporation Page 7 June 2009 Rev E2 Finisar FWLF-1631-xx DWDM SFP - June 2009 IX. Serial Communication Protocol All Finisar SFPs support the 2-wire serial communication protocol to provide module ID information as outlined in the SFP MSA1. These SFPs use an Atmel AT24C01A 128 byte E2PROM with an address of A0h. For details on interfacing with the E2PROM, see the Atmel data sheet titled "AT24C01A/02/04/08/16 2-Wire Serial CMOS E2PROM."7 Finisar SFPs also support diagnostic features as described in Finisar Applications Note AN-20304 and SFF-84728, "Digital Diagnostic Monitoring Interface for Optical Transceivers". A controller IC that monitors system parameters such as laser current, module temperature, transmitter power, and received power is accessible at address A2H. In addition, Finisar's DWDM SFPs provide extended set of ID information and diagnostic features as described in the DWDM SFP MSA6. I2C clock speed, digital diagnostic accuracy and digital diagnostic range can be found in the table below. Values in the table represent the worst-case values over temperature, voltage, and life.
