Overview
The FDB-1048 is a USB-connected interface unit for T-XFP and T-SFP+ transceivers.
Access to the I2C interface of the transceiver, as well as interfacing some other hardware
signals such as MOD_ ABS, RX_LOS and TX_DISABLE is possible via a PC connection.
This connection is made through USB 2.0, via Windows built-in HID driver. A proprietary
protocol controls and communicates with the processor in the FDB-1048 from the
different PC applications.
It has a convenient small and robust design, which together with the simple USB-
only powered solution, makes it the perfect tool also for using in field applications.
Applications include Part number and Serial number (PID) readouts and tuning a Tunable
XFP or SFP+ transceiver.
The three LEDs on the front panel represent (bottom-top): “Module Present”, “Activity”
and “RX LOS”.
