APPLICATIONS
Finisar’s Dense Wavelength-Division Multiplexing (DWDM) Small Form Factor
Pluggable (SFP) transceivers1 address communication network optics requirements that
necessitate lower power and cost parameters. The FWLF-1631-xx is designed expressly
for service providers deploying SONET and DWDM2 networking equipment in
metropolitan access and core networks; and is RoHS 5-of-6 compliant per Directive
2002/95/EC3 and Finisar Application Note AN-20384. It is also compatible to Gigabit
Ethernet data rate.
Basic digital diagnostic features for the FWLF-1631-xx are implemented as described in
Finisar Application Note AN-2030, “Digital Diagnostic Monitoring Interface for Optical
Transceivers”5. Enhanced diagnostic features are available as described in the DWDM
SFP MSA6.

Notes:
1. Parameters are specified over temperature and voltage, at end of life unless otherwise noted.
2. All parameters are measured on a Finisar SFP Evaluation Card unless otherwise noted.
3. For accurate ∆λ20 measurements, an OSA with a resolution band width of ≤ 20pm is recommended.
4. Tolerable back reflection is the max back reflection level at which the power penalty will be <1dB.
5. Dispersion power penalty is measured in loop back with OSNR set to 28 dB. Data rate and pattern used same as specified
for Optical Input Power. Dispersion power penalty is the difference in Rx power at a BER of 10-12 for 0ps/nm and
2400ps/nm.
6. Dispersion noise penalty is measured in loop back with Rx power set between -9dBm and -22dBm. Data rate and pattern
used same as specified for Optical Input Power. Dispersion noise penalty is the difference in OSNR at a BER of 10-12 for
0ps/nm and 2400ps/nm.

VI. Wavelength Stabilization
The laser transmitter will not be turned on until its temperature is adjusted to ensure
operation within the specified channel (X +/- 300pm). This temperature stabilization time
is dependent on the ambient temperature conditions, but will typically occur within 5
seconds of powering the device. The module will transmit within the specified
wavelength tolerance (X +/- 100pm) within 10 ms of transmitter operation.

IX. Serial Communication Protocol
All Finisar SFPs support the 2-wire serial communication protocol to provide module ID
information as 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 SFPs also support diagnostic features as described in Finisar Applications Note
AN-20304 and SFF-84728, “Digital Diagnostic Monitoring Interface for Optical
Transceivers”. A controller IC that monitors system parameters such as laser current,
module temperature, transmitter power, and received power is accessible at address A2H.
In addition, Finisar’s DWDM SFPs provide extended set of ID information and diagnostic
features as described in the DWDM SFP MSA6.
I2C clock speed, digital diagnostic accuracy and digital diagnostic range can be found in
the table below. Values in the table represent the worst-case values over temperature,
voltage, and life.
