Preliminary Product Specification 

DWDM SFP Transceiver 

FWDM-1629-XX 

 

 

PRODUCT FEATURES 

 

 

Up to 1.25 Gb/s bi-directional data 
links 

 

Hot-pluggable SFP footprint 

 

Temperature-stabilized DWDM-
rated DFB laser transmitter 

 

100GHz ITU Grid, C Band 

 

Low dispersion DFB laser suitable 

 

Metal enclosure for low EMI 

 

Extended operating range: -5°C to 
70°C case temperature 

 

Wavelength controlled within 

±

 0.1 

nm over life and temperature 

 

Extended link budget with APD 
receiver technology 

 

GbE and 1X FC compliant 

 

 

 

 
 

              APPLICATIONS 

 

 

Amplified DWDM networks 

 

Bandwidth aggregation 

 

Ring topologies with OADM 

 

 

 
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”
