Finisar’s Dense Wavelength-Division Multiplexing (DWDM) Small Form Factor

Pluggable (SFP) transceivers

address communication network optics requirements that

necessitate lower power and cost parameters. The FWLF-1631-xx is designed expressly

for service providers deploying SONET and DWDM

networking equipment in

metropolitan access and core networks; and is RoHS 5-of-6 compliant per Directive

2002/95/EC

and Finisar Application Note AN-2038

. It is also compatible to Gigabit

Ethernet data rate.

Basic digital diagnostic features for the FWLF-1631-xx are implemented as described in

Finisar Application Note AN-2030, “Digital Diagnostic Monitoring Interface for Optical

Transceivers”

. Enhanced diagnostic features are available as described in the DWDM

SFP MSA

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 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.
