USB 2.0 is a USB interface standard released in 2000 with a theoretical maximum transmission speed of 480Mbps (about 60MB/s). The port has four cables (five cables for MicroUSB and MiniUSB), and the maximum output current is 0.5A. USB 2.0 is currently the most common version of USB port, almost all computers have USB 2.0 port, most USB devices also support USB 2.0. USB 2.0 hub. The device can provide USB high speed or full speed connection on the uplink port. The device also provides USB high-speed, full-speed, or low-speed connections on the downlink port. When the uplink port is connected to an electrical environment that supports only high-speed, full-speed, and low-speed connections, the high-speed, full-speed, and low-speed USB connections on the downlink port are enabled. When the uplink port is connected to an electrical environment that supports only full or low speed connections, the USB high-speed connection on the downlink port is disabled. USB 3.0 Hubs is higher than usb 2.0 in terms of transmitting data.

Specifications
1. outdoor distributionÂ
2. suitable for aerial, pipeline laying methodÂ
3.Long distance and local area network communication
1. Description
Â
Low dispersion and attenuation
Proper design, precise control for fiber excess length and distinct stranding process render the cable excellent mechanical and environmental properties
Double-jacket structure make cable have nice properties of moisture resistance and crush resistance
With small cable diameter, light cable weight, easily to lay
Â
2.FeatureÂ
                                                                        Â
 To fill the single mode or multi-mode fibers into the PBT loose tube made of high modulus polyester.
 The inside of the tube is filled with water-proof compounds.
 The outside of loose tube is longitudinally wrapped with plastic coated steel tapes.
 Between the steel tape and the loose tube, water-proof material is filled to ensure the compactness and the water resistence of the cable.
Two parallel steel wires are placed at the two sides of the steel tape. The steel wires are all inside the (PE) outer jacket.
