APPLICATIONS
Finisar’s Dense Wavelength-Division Multiplexing (DWDM) transceivers offer DWDM
transport with dramatically lower power and cost in a standard pluggable Small Form
Factor Pluggable (SFP) package. The FWDM-1629 is designed expressly for service
providers deploying DWDM networking equipment in metropolitan Ethernet and SAN
networks. The fiber link budget has been enhanced to 30dB with an Avalanche Photo
Diode (APD) receiver.
In addition, digital diagnostic features are implemented as described in Finisar
Application Note AN-2030, “Digital Diagnostic Monitoring Interface for Optical
Transceivers”2.

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 90
seconds of powering the device. The device will transmit within the specified wavelength
tolerance (X +/- 0.1nm) within 5 seconds of transmitter operation.

IX. Serial Communication Protocol
All Finisar SFPs support the 2-wire serial communication protocol 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.”4
Finisar’s DWDM SFPs 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.
