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.

IX. Serial Communication Protocol

All Finisar SFPs support the 2-wire serial communication protocol to provide module ID information as outlined in the SFP MSA

E

2

1

. These SFPs use an Atmel AT24C01A 128 byte

2

PROM with an address of A0h. For details on interfacing with the E

Atmel data sheet titled “AT24C01A/02/04/08/16 2-Wire Serial CMOS E 2

PROM, see the

PROM.” 3

Finisar SFPs also support diagnostic features as described in Finisar Applications Note AN-

2030

4

and SFF-8472

5 , “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 MSA

6

.

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.
