摘要:
Disclosed is a distributed controlled passive optical network system and bandwidth control method thereof. The system comprises an optical line terminal (OLT), plural optical network units (ONUs) and a splitter with combiner. Each ONU has a first Tx/Rx for respectively transmitting and receiving data packets on an upstream data channel and a downstream data channel, and a second Tx/Rx for transmitting and receiving control signals/commands on a control channel. Upstream data of each ONU is carried by the upstream data channel and sent to the OLT through the splitter with combiner. Downstream data of the OLT is carried by the downstream data channel and sent to corresponding ONUs through the splitter with combiner. With the control signals/commands carried by the control channel, the required information of network status among the ONUs is provided.
摘要:
An FFT processor is disclosed, which includes a first multi-pipelined MDC unit, a second multi-pipelined MDC unit and a switching network. The first multi-pipelined MDC unit and the second multi-pipelined MDC unit respectively employ a plurality of MDC circuits to change the positions of the delayers thereof in parallel way. By changing the operation time sequence of the signals in the first multi-pipelined MDC unit and the second multi-pipelined MDC unit, the first multi-pipelined MDC unit is able to directly send the operation results to the second multi-pipelined MDC unit through the switching network.

摘要:
The present invention relates to an improved optical device for optical mouse, being installed inside the case body of the optical mouse, comprising: a LED, a lens mount, a sensor and a digital signal processor. That is, instead of using the LED, the LED assembly clip, the positioning holes and the lens mount, which are separated from and independent to one another, for fixing the LED inside the optical mouse, the present invention uses a combined device featuring fool-proof, and positioning-insetting-all-in-one concept can place the LED precisely at the first lens of the lens mount and is capable of installing the LED accurately onto the lens mount and the same time rapidly and effectively adjusting and fixing the relative angle and position as seen in FIG. 6 between the lens mount and the LED. Moreover, the combined device is easy to positioned such that the forgoing shortcomings of high manufacturing cost and difficult to mass-produced are avoided.
摘要:
An all-optical label swapping system and method superimposes a low-speed ASK label on top of a high-speed DC-balanced-line-coded ASK payload. An old ASK label is erased by modulating the combined payload and label signal with the inverse of the received ASK label. This ASK labeling technique requires only low speed external modulators and low speed optical receivers to perform the label swapping mechanism, and does not require sophisticated optical components.
