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
2
Transceivers"
.

FWDM-1629-XX DWDM SFP Preliminary Product Specification – February 2005 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. - Page 8 FWDM-1629-XX DWDM SFP Preliminary Product Specification – February 2005 IX.
