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) package1. The FWLF-1631 is designed expressly for service
providers deploying DWDM networking equipment in metropolitan access and core
networks2. The transceiver is RoHS compliant and lead free per Directive 2002/95/EC3,
and Finisar Application Note AN-20384.
Basic digital diagnostic features for the FWLF-1631 are implemented as described in
Finisar Application Note AN-2030, “Digital Diagnostic Monitoring Interface for Optical
Transceivers”5. Optional enhanced digital diagnostic features are available per the
DWDM SFP MSA6.

2. All parameters are measured on a Finisar SFP Evaluation Card unless otherwise noted.
3. Dispersion power penalty is measured in loop back with OSNR set at Rx < 28 dB. Data rate and pattern used
same as specified for Optical Input Power. Dispersion penalty is measured at BER = 10-10
4. OSNR power penalty is measured in loop back. Data rate and pattern used is same as specified for Optical
Input Power. OSNR penalty is measured at BER = 10-10
5. Tolerable back reflection is the max back reflection level at which the power penalty will be <1dB. Power
penalty is measured over fiber (2400ps/nm) at BER = 10-10 under high OSNR (>28dB) conditions.

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 30
seconds of powering the device. The device will transmit within the specified wavelength
tolerance (X +/- 0.1nm) within 5 seconds of transmitter operation.

IX. Serial Communication Protocol
All Finisar SFPs support the 2-wire serial communication protocol 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.”7
Finisar’s DWDM SFPs also support extended diagnostic features as described in Finisar
Applications Note AN-2030, “Digital Diagnostic Monitoring Interface for Optical
Transceivers”5. (Additional information is available in document titled: “Digital Diagnostic
Monitoring Interface for Optical Transceivers Rev 9.3”8). A controller IC that monitors
system parameters such as laser current, module temperature, transmitter power, and
received power is accessible at address A2H.
