OPTICAL MODULE

摘要

An integrated apparatus with optical/electrical interfaces and protocol converter on a single silicon substrate. The apparatus includes an optical module comprising one or more modulators respectively coupled with one or more laser devices for producing a first optical signal to an optical interface and one or more photodetectors for detecting a second optical signal from the optical interface to generate a current signal. Additionally, the apparatus includes a transmit lane module coupled between the optical module and an electrical interface to receive a first electric signal from the electrical interface and provide a framing protocol for driving the one or more modulators. Furthermore, the apparatus includes a receive lane module coupled between the optical module and the electrical interface to process the current signal to send a second electric signal to the electrical interface.

1. An integrated apparatus with optical/electrical interfaces and protocol converter on a single silicon substrate, the apparatus comprising:
an optical module comprising one or more modulators respectively coupled with one or more laser devices for producing a first optical signal to an optical interface, and one or more photodetectors for detecting a second optical signal from the optical interface to generate a current signal; a transmit lane module coupled between the optical module and an electrical interface, the transmit lane module comprising at least a modulation driver configured to receive a first electric signal from the electrical interface and provide a framing protocol for driving the one or more modulators; a receive lane module coupled between the optical module and the electrical interface, the receive lane module comprising at least a transimpedance amplifier configured to process the current signal to send a second electric signal to the electrical interface; wherein the first/second optical signal is associated with one or more wavelengths configured in a coarse wavelength division multiplex (CWDM) grid or a dense wavelength division multiplex (DWDM) grid.
