APPLICATIONS
Amplified DWDM networks
Bandwidth aggregation
Ring topologies with fixed and
reconfigurable OADMs
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
1
. The FWLF1634R is designed expressly for service
providers deploying DWDM networking equipment in metropolitan access and core
networks.
Basic digital diagnostic features for the FWLF1634R are implemented as described in
Finisar Application Note AN-2030, “Digital Diagnostic Monitoring Interface for Optical
Transceivers”
4
. Enhanced diagnostic features are available as described in the DWDM
SFP MSA

<0.8V.
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. Receiver achieves multi-rate 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.

Loss of signal (LOS) is LVTTL. Logic 0 indicates normal operation; logic 1 indicates no signal detected.
Receiver sensitivity is compliant with power supply sinusoidal modulation of 20 Hz to 1.5 MHz up to specified
value applied through the recommended power supply filtering network.
