Dual frequency band refers to the characteristic that the same communication device can work in two frequency bands. There are many applications, such as dual-band routers. A dual-band router refers to a router that supports two channels, one 2.4G channel and one 5G channel. Generally, routers are designed to be 2.4GHZ, so there will be mutual interference between signals in the same area. At this time, if you choose the 5.GHZ frequency band mode, it will effectively avoid signal interference in these frequency bands, and wireless signals will be transmitted accordingly. farther.
ONU (Optical Network Unit) optical network unit, ONU is divided into active optical network unit and passive optical network unit. Generally, devices equipped with network monitoring including optical receivers, upstream optical transmitters, and multiple bridge amplifiers are called optical nodes. The PON uses a single optical fiber to connect to the OLT, and then the OLT connects to the ONU. ONU provides services such as data, IPTV (i.e. interactive network television), and voice (using IAD, i.e. Integrated Access Device), truly realizing "triple-play" applications. 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.
