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

nm over life and temperature
• Extended link budget with APD
receiver technology
• GbE and 1X FC compliant
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.
APPLICATIONS
• Amplified DWDM networks
• Bandwidth aggregation
• Ring topologies with OADM

Notes:
1. Circuit ground is internally isolated from chassis ground.
2. Laser output disabled on T
3. Should be pulled up with 4.7k – 10kohms on host board to a voltage between 2.0V and 5.5V.
MOD_DEF(0) pulls line low to indicate module is plugged in.
4. Finisar 2x receiver achieves simultaneous 1x and 2x operation without active control.
5. LOS is open collector output. Should be pulled up with 4.7k – 10kohms on host board to a voltage
between 2.0V and 5.5V. Logic 0 indicates normal operation; logic 1 indicates loss of signal.
