Optical bypass 1+1 protection equipment

The optical bypass 1+1 protection device is a protection device for optical fiber networks that can automatically bypass faulty optical fiber links to ensure the normal operation of the network.

The working principle of optical bypass 1+1 protection equipment is to use optical switches to switch optical fiber links. Under normal circumstances, both the active optical fiber link and the backup optical fiber link are in working condition. When the main optical fiber link fails, the optical switch will automatically switch the optical signal to the backup optical fiber link to ensure the normal operation of the network.

Compared with optical bypass 1:1 protection equipment, optical bypass 1+1 protection equipment has a higher protection level. In an optical bypass 1:1 protection device, if the backup fiber link also fails, the network will be disrupted. In optical bypass 1+1 protection equipment, even if the backup fiber link fails, the network can still continue to operate because there is another backup fiber link to provide protection.

Of course, the cost of optical bypass 1+1 protection equipment is also higher. Therefore, when selecting optical bypass protection equipment, you need to make trade-offs based on actual needs.
