Abstract
Optical modules for use with a host system. In one example embodiment, a method for tapping an optical network includes connecting one or more optical modules to a host device, providing one or more post amplifiers, and controlling each of the one or more optical modules and the one or more post amplifiers with a microprocessor that is integrated with the host device. In this example method, the one or more optical modules include at least one optical module with a plurality of ROSAs and the post amplifiers amplify electrical signals generated by the ROSAs.
Claims20
An optical transceiver module comprising:
- a ROSA configured to receive an optical signal and deliver the optical signal as an electrical signal to a host device for processing including amplification by a post amplifier of the host device;
- a first lead frame electrically connected to the ROSA;
- a TOSA configured to transmit an optical signal based on an electrical signal received from the host device;
- and
- a second lead frame electrically connected to the TOSA;
- wherein the first lead frame is configured to be electrically connected to a post amplifier and the second lead frame is configured to be electrically connected to a laser driver, the post amplifier and the laser driver being integrated into a host printed circuit board of the host device, the host printed circuit board including a microprocessor configured to control the post amplifier and the laser driver.
An optical receiver module comprising:
- a first ROSA configured to deliver a first electrical signal to a host device;
- a first lead frame electrically connected to the first ROSA;
- a second ROSA configured to deliver a second electrical signal to the host device;
- and
- a second lead frame electrically connected to the second ROSA;
- wherein the first lead frame is configured to be electrically connected to a first post amplifier configured to amplify the first electrical signal and the second lead frame is configured to be electrically connected to a second post amplifier configured to amplify the second electrical signal, the first and second post amplifiers being integrated into a host printed circuit board of the host device, the host printed circuit board comprising a microprocessor configured to control the first and second post amplifiers.
A method for tapping an optical network, the method comprising:
- connecting one or more optical modules to a host device, wherein the one or more optical modules include at least one optical module with a plurality of ROSAs;
- providing one or more post amplifiers to amplify electrical signals generated by ROSAs included in the one or more optical modules, the one or more post amplifiers integrated with the host device;
- and
- controlling each of the one or more optical modules and the one or more post amplifiers with a microprocessor that is integrated with the host device.
