Laser transmitter and process for transmitting controlled light signals |
摘要 |
A laser transmitter comprising a laser diode (1) and a monitoring photodiode (2) adapted to receive a small part (LS1) of a light signal (LS) of the laser diode and to derive therefrom an output current (SC). The transmitter further comprises regulation means (4) adapted for receiving the output current and for sending a signal (CS) to a current driver (5) in order to regulate the input current (IC) of the laser diode (1) as a function of this output current (SC). The transmitter also comprises a register (6) adapted to store data to be used by the regulation means (4) or to be read by a serial interface, and pattern detection means (7) adapted to scan all the traffic and thus all the packets of the upstream flow to the laser diode (1) to check whether pre-determined bit-patterns are present.
