摘要： An LD driver to generate an asymmetrical driving current with a relatively faster falling edge and an optical transmitter having the LD driver are disclosed. The LD driver includes a primary driver and the sub-driver connected in parallel to the primary driver. The primary driver converts the input signal or the delayed signal delayed from the input signal into the primary current. The sub-driver generates a symmetrical current tracing the input or the delayed signal, and an asymmetrical current formed by the OR operation between the input and delayed signals. The driving current is formed by adding the primary current, the symmetrical current and the asymmetrical current.

摘要： The present invention provides an optical receiver that includes a monitoring unit with a function to prevent the unit from misjudging of the loss-of-signal state. In particular, the present invention is applicable to the monitoring unit that receives the signal to be judged from the processing unit posterior to the optical converting unit that couples with the processing unit via the capacitor. The signal reflects the second or higher order response lag due to the coupling capacitor. The monitoring unit of the invention generates the loss-of-alarm signal when the signal is continuously smaller than the first reference by a preset time and continuously greater than the second reference by the present time.
