Patent ID: 8380073

Claim:
An optical transceiver, comprising: a TOSA configured to install a semiconductor LD integrated with an optical modulator, said TOSA providing a first group of lead pins and a second group of lead pins; a first circuit board configured to mount a driving circuit that generates a driving signal to drive said optical modulator; a second circuit board configured to mount a bias circuit that provides a bias to said semiconductor LD; an LF FPC board configured to connect said first circuit board to said second circuit board electrically; an RF FPC board configured to connect said TOSA directly to said first circuit board, wherein said first group of lead pins of said TOSA transmitting said driving signal and directly connected to said RF FPC board, said second group of said lead pins providing said bias to said TOSA, and wherein said driving signal is provided to said TOSA through said RF FPC board without transmitting in said second circuit board.
