APPLICATIONS
•
•
•
ITU grid optical networks
Bandwidth aggregation
Ring topologies with OADM
Finisar’s Dense Wavelength-Division Multiplexing (DWDM) transceivers offer DWDM
transport with dramatically lower power and cost in a standard plugable GBIC package.
The FTR-1629 is designed expressly for service providers deploying DWDM networking
equipment in metropolitan access and core networks. The fiber link budget has been
enhanced to 30dB with an Avalanche Photo Diode (APD) receiver.
The
FTR-1629 has serial identification features as described for Module Definition “4”
GBICs in the GBIC Specification Revision 5.5
1
. In addition, digital diagnostic features
are implemented as described in Finisar Application Note AN-2030, “Using the Finisar
GBIC I

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 XI, “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 5.5
