What is a Reverse Exchange?
The reverse power supply switch supports the IEEE802.3af / at power supply standard. It takes power through the network and eliminates the power wiring of the switch. It is a device that expands the network and can provide more connection ports in the sub-network in order to connect more Computer. It has the characteristics of high cost performance, high flexibility, relatively simple, and easy to implement. It is widely used in the construction of broadband networks.
Reverse power switch
- The reverse power supply switch supports the IEEE802.3af / at power supply standard. It takes power through the network and eliminates the power wiring of the switch. It is a device that expands the network and can provide more connections in the subnet.
- A complete PoE system including power supply equipment
- (1) Solved the problem of difficult access to power for access equipment in special environments
- (2) Provide a more flexible supplementary power supply scheme, speed up the progress of network construction, and realize the rapid deployment of services.
- (3) There is no need to lay a power line to supply power to the access equipment, which reduces the input of power supply and saves engineering investment;
- (4) Reverse power supply method is used to achieve the passiveness of user-side equipment, network failures are greatly reduced, and network stability is improved.
- (5) Reduce maintenance workload, save human resources for maintenance, and save operation and maintenance costs.
- (6) Adopting reverse power supply technology, only when users use it, it will be powered on and work green.
- Broadband access
- Reverse power supply can only achieve two levels of power supply at present, and is limited to access switches. It is expected that in the next year, it will be able to achieve passive access to the aggregation switch. In the next 3-5 years, reverse power supply switches will lead China The broadband access market has become the mainstream access method for broadband operations.
