Description
AirPass21TM is Wireless Laser Link System
The next generation wireless free space telecommunication network instead of conventional optical fiber network.
AirPass21TM is for expanding already existing optical telecommunication network for installing new optical network.
AirPass21TM is economical and took shorter time to build network compared to conventional optical fiber network.
Features
- Cost effective because of no optical fiber installation necessary.
- No feder or local government permission necessary.
- High reliability and to adaption of transmission speed due to long distance optical transmission parts.
- Compatibility with conventional optical systems due to the application of 785nm band.
- No harm to the human due to use of 785nm.
-ANSI and ICE Class3 Eye safety.
- Can be used for common base
-Regardless contents of transmission data and protocol.
Main Applications
- All system for 802.3
- Hub <--> Hub
- Repeater <--> Repeater
- PC <--> PC
