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 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 MSA6.

Notes:
1. Parameters are specified over temperature and voltage, at end of life, and for non-rate select option 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. Output power of +3 to +7dBm is also supported; please contact your local Finisar sales representatives for details.
5. Tolerable back reflection is the max back reflection level at which the power penalty will be <1dB. Power penalty is measured
over fiber (1600ps/nm) at BER = 10-12 with OSNR set at 24dB.
6. Dispersion power penalty is measured in loop back with OSNR set to 30 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 & 1600ps/nm
7. Rx power set between -9dBm and -18dBm. Data rate and pattern used same as specified for Optical Input Power. Measured as
the Minimum OSNR to achieve a BER of 10-12 . Optical filter bandwidth of 0.1nm is used in OSNR measurement.

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.”3
Finisar SFPs also support diagnostic features as described in Finisar Applications Note AN-
20304 and SFF-84725, “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.
