It is understood that Macao has been researching and introducing LED traffic lights since 2007, and testing LED traffic lights, maintenance rates and signal forms of different brands in different origins according to national standards, and selecting LED traffic lights suitable for Macao environment. After a period of field use testing, the results are satisfactory. It operates stably in rainy weather in Macau, and the projected light, amount of light and image also meet safety requirements. To this end, the Macau Transportation Bureau began to replace LED traffic lights.
With the operation of LED traffic lights, the total power consumption of traffic lights in Macau is expected to be reduced by five to sixty percent, and the failure rate of traffic lights and the number of replacement parts can be reduced.
Compared to single band, the most competitive advantage of dual band is the equipment can work along with 2 bands together at the same time. This enlarges the application range of the equipment and allows it to fucntion under multi conditions, which is way better than the single band one.
Nowadays, with the development of the econimics, more and more countries started to build up the PON (Passive Optical Network) instead of working with the AON (Active Optical Network). The former obviously possesses more advantages than the latter, which is due to not only the non-power-required characteristic but also the advanced technologies.
The ONU has two functions: it selectively receives the broadcast sent by the OLT, and responds to the OLT if the data needs to be received; collects and buffers the Ethernet data that the user needs to send, and sends it to the OLT according to the assigned sending window The end sends the buffered data. The application of ONU can effectively improve the uplink bandwidth utilization of the entire system, and it can also configure the channel bandwidth according to the network application environment and applicable service characteristics to carry as many end users as possible without affecting the communication efficiency and communication quality, and improve the network utilization Rate and reduce user costs.
