APPLICATIONS
Finisar’s Dense Wavelength-Division Multiplexing (DWDM) transceivers offer DWDM
transport with dramatically lower power and cost in a standard pluggable GBIC package.
The FTR-1631 is designed expressly for service providers deploying DWDM networking
equipment in metropolitan access and core networks.
The FTR-1631 has serial identification features as described for Module Definition “4”
GBICs in the GBIC Specification Revision 5.51 . In addition, digital diagnostic features
are implemented as described in Finisar Application Note AN-2030, “Digital Diagnostic
Monitoring Interface for Optical Transceivers”2 .

Low Speed Signals
RX_LOS, TX_DISABLE, and TX_FAULT are TTL signals as described in Table 3.
MOD_DEF(1) (SCL) and MOD_DEF(2) (SDA) are open drain CMOS signals (see
section IX, “Serial Communication Protocol”). Both MOD_DEF(1) and MOD_DEF(2)
must be pulled up to host_Vcc. For more detailed information, see sections 5.3.1 – 5.3.8
in the GBIC Specification Revision 5.51 .

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 GBIC (90 seconds maximum). The device will transmit within
the specified wavelength tolerance (X +/- 0.1nm) within 5 seconds of transmitter
operation.

IX. Serial Communication Protocol
All Finisar optical GBICs implement serial identification features described for ‘Module
Definition “4”’ as outlined in Annex D of the GBIC Specification 1 . These GBICs use an
Atmel AT24C01A 128 byte E2 PROM at address A0H. For details on interfacing with the
E2 PROM, see the Atmel data sheet titled “AT24C01A/02/04/08/16 2-Wire Serial CMOS
E2 PROM.”3
Finisar’s DWDM GBICs also support extended diagnostic features as described in
Finisar Applications Note AN-2030, “Digital Diagnostic Monitoring Interface for Optical
Transceivers”2 . A controller IC that monitors system parameters such as laser current,
module temperature, transmitter power, and received power is accessible at address A2H.
