Patent ID: 8014680

Claim:
An optical transceiver comprising: a transmitter unit including an equalizing (EQ) filter which can reduce jitter of a high speed electric signal; a control circuit which controls the EQ filter; a receiver unit which receives an optical signal; and a micro-controller which controls the transmitter unit and the receiver unit, wherein the optical transceiver is an XFP transceiver (10 Gb/s small form-factor pluggable) or a 300-pin Multi-Source Agreement (MSA) transceiver, wherein when the optical transceiver is an XFP transceiver (10 Gb/s small form-factor pluggable), the transmitter unit comprises a Clock and Data Recovery (CDR) unit, a Laser Diode (LD) driver, and a Transmitter Optical Sub-Assembly (TOSA), and the EQ filter is interposed between the CDR unit and the LD driver, and when the optical transceiver is a 300-pin Multi-Source Agreement (MSA) transceiver, the transmitter unit comprises a serializer, the LD driver, and a Laser Diode (LD) module, and the EQ filter is interposed between the serializer and the LD driver, wherein the EQ filter comprises: a receiver which receives an electric signal from the CDR unit or the serializer; an output driver which directly receives the signal outputted from the receiver; and a pre-emphasis driver which receives the signal outputted from the receiver via a delay device, and wherein the optical transceiver comprises a filter control circuit that is connected to the micro-controller to control the EQ filter.
