Functional Description of SFF Transceiver
This transceiver is designed to transmit serial data via single
mode fiber.

The transmitter part converts electrical LVPECL compatible
serial data (TD+ and TD
The module has an integrated shutdown function that switches
the laser off in the event of an internal failure.
Reset is only possible if the power is turned off, and then on
again. (V
The transmitter contains a laser driver circuit that drives the
modulation and bias current of the laser diode. The currents are
controlled by a power control circuit to guarantee constant out-
put power of the laser over temperature and aging. The power
control uses the output of the monitor PIN diode (mechanically
built into the laser coupling unit) as a controlling signal, to pre-
vent the laser power from exceeding the operating limits.
