無線通信システムおよび無線ラジオ周波数装置
Document Type and Number:
Japanese Patent JP6899856
Kind Code:
B2
Abstract:
To provide a wireless communication system and a wireless radio frequency device.SOLUTION: A wireless communication system 100 includes a baseband processing unit, an optical multiplexer, and M first optical transceivers, and a wireless radio frequency device 500. The M first optical transceivers are provided between the baseband processing unit and the optical multiplexer. Each of the M first optical transceivers has a different operation wavelength. M is an integer of 2 or higher. The wireless radio frequency device includes M remote wireless units, M second optical transceivers, and at least one optical splitter. An operation wavelength of the first optical transceiver matches an operation wavelength of the second optical transceiver corresponding to the first optical transceiver. The M second optical transceivers are connected to the same optical fiber by at least one optical splitter. The optical fiber is connected to the optical multiplexer and at least one optical splitter.SELECTED DRAWING: Figure 1
