Laser lit flat panel displays are disclosed including edge-lit and direct lit backlights. In certain embodiments, laser assemblies are selected to obtain bandwidth distributions to reduce speckle.

The invention provides an optical line terminal (OLT), an optical network unit (ONU), a passive optical network system, an uplink bandwidth distribution method and a rate adaptation method. The OLT comprises an optical module, a clock data recovery module, a media access control (MAC) chip and a control module, wherein the optical module is used for receiving uplink data sent by the ONU at different sending rates and sending the uplink data to the clock data recovery module; the clock data recovery module is used for receiving the uplink data, recovering a clock signal according to the uplink data and sending the uplink data and the corresponding clock signal to the MAC chip simultaneously; the MAC chip is used for storing the uplink data and the corresponding clock signal; and the control module is used for acquiring an uplink rate of the uplink data according to the clock signal corresponding to the uplink data and distributing an uplink bandwidth to the ONU according to the uplink rate. According to the invention, under the conditions that the conventional wavelength resource is not occupied and the performance of an optical uplink is not degraded, coexistence of a plurality of rate time division multiplexes is supported.
