Abstract:
1. An apparatus, comprising: a top open transmitter optical subassembly (TOSA), the TOSA having: a power supply coupled to the laser diode anode and to the first terminal of the first capacitance; a second capacitance having a first terminal coupled to the TOSA case and the second terminal of the first capacitance, the second capacitance having further a second terminal coupled to the power supply, to the laser diode anode, and to the first terminal of the first capacitance; and a switch having an input terminal coupled to the first terminal of the second capacitance, to the TOSA case ground, and to the second terminal of the first capacitance, the switch having further a first output terminal coupled to a TOSA case ground, a second output terminal coupled to an electrical ground for the apparatus, and a third floating output terminal.
