Finisar’s FTR-1621T-XX CWDM Extended Temperature GBIC transceivers comply
with GBIC Specification Revision 5.51*. They are compatible with Gigabit Ethernet as
specified in IEEE 802.32*, single and double rate Fibre Channel FC-PH, PH2, PH33* and
SONET specifications for OC-12/OC-48 4**. Along with an extraordinary operation
range of –40oC to 85oC, the fiber link budget has been enhanced with an Avalanche
Photo Diode (APD) receiver.
Additional real time diagnostic functions are available via the 2-wire serial bus specified
for Module Definition “4” GBICs. For details, see Finisar Application Note AN-2030,
“Digital Diagnostic Monitoring Interface for Optical Transceivers”5. Even with all of
these innovative features, the transceiver is still compliant with the mechanical and
electrical interfaces defined in the GBIC interoperability standard.

III. 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 VIII, “Serial Communication Protocol”). Both MOD_DEF(1) and MOD_DEF(2)
must be pulled up to host_Vcc. Note – MOD_DEF(0) is grounded inside the GBIC to
indicate the correct mode of operation.
For more detailed information, see sections 5.3.1 – 5.3.8 in the GBIC Specification Rev.
5.51.

VIII. Serial Communication Protocol
All Finisar optical GBICs are ‘Module Definition “4”’ and support the 2 wire serial
communication protocol outlined in the GBIC Specification 1. These GBICs use an
Atmel AT24C01A 128 byte E2PROM (with an address of 1010000X). For details on
interfacing with the E2PROM, see the Atmel data sheet titled “AT24C01A/02/04/08/16 2Wire Serial CMOS E2PROM.”6
All Finisar optical GBICs also incorporate a controller IC that monitors system
parameters such as laser current, laser temperature, and, in the case of
13xx/14xx/15xx/16xx nm parts, transmitted power. For a complete description of how to
use Finisar’s extended features, see Finisar’s Application Note AN-20305.

following optical parameters: laser wavelength, receiver sensitivity, and transmit output
power. See Table 6 for details.
