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

1

. These SFPs use an Atmel AT24C01A 128 byte

E

2

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

2

PROM, see the

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

2

PROM.”

7

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

AN-2030

4

and SFF-8472

8

, “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

.

I2C clock speed, digital diagnostic accuracy and digital diagnostic range can be found in
