Abstract
An optical receiver circuit is disclosed. This receiver included in receiver optical sub-assembly (ROSA) adjusts bandwidth based on a voltage level detection at a receiver signal strength indication (RSSI) pin, or rate-adaptively adjusts the bandwidth of optical receiver circuit based on operation data rate.
Claims29
A receiver comprising:
- an optical receiver circuit to adjust bandwidth based on a voltage level at a receiver signal strength indication (RSSI) pin;
- and
- a bandwidth adjustment circuit to indicate an operation data rate by detecting the voltage level on the RSSI pin.
A method comprising:
- comparing a voltage applied to a receiver signal strength indication (RSSI) pin at an optical receiver circuit in a receiver optical sub-assembly (ROSA) to a reference voltage;
- and
- adjusting the bandwidth based of the ROSA circuit based on the voltage.
A system comprising:
- a notebook computer base;
- a first receiver coupled to the notebook base;
- a waveguide coupled to the first transceiver;
- a second receiver coupled to the waveguide;
- and
- a display panel coupled to the second receiver;
- wherein the first receiver and the second receiver each include:
- a receiver optical sub-assembly (ROSA) circuit to adjust bandwidth based on a voltage level at a receiver signal strength indication (RSSI) pin;
- and
- a bandwidth adjustment circuit to indicate an operation data rate by applying the voltage level to the RSSI pin.
7 more elements
A receiver comprising:
- a receiver optical sub-assembly (ROSA) circuit to receive optical input/output (I/O) data;
- and
- a control circuit to automatically adjust the operating bandwidth of the ROSA circuit based on the I/O data rate.
