大气激光通信是利用激光通过大气进行信息传递的一种通信方式。大气激光通信设备可传输多种速率的数据、语音、图像信息,具有无电磁干扰、组网机动灵活、通信可靠性高、保密性好、性价比高等优点,应用前景十分广阔。与无线电通信相比,大气激光通信具有不挤占无线电频率资源、电磁兼容性好、抗电磁干扰能力强、且不干扰其他传输设备、保密性强等特点。具有安装便捷、使用方便,很适合于在特殊地形、地貌及有线通信难以实现和机动性要求较高的场所工作。与光纤通信相比,大气激光通信具有建网灵活快捷,运行安全,不易被窃听,可移动,可升级等优点。因此,大气激光通信可极大地提高光通信系统的通信能力。武汉嘉铭激光有限公司与俄罗斯激光专家开展国际合作,与俄方推出几款先进的大气激光通信设备,技术指标先进,产品可靠性高,性价比优。设备主要特点: 1、 具有高速的信息传输速率,高达10Gbit /s。 2、 最大通信距离达7KM,双信道保证在恶劣天气情况下也能达到7KM。 3、 最小激光束散角0.2mard。有效阻止其它信号影响。 4、 具有快速自动跟踪系统(ATP),能有效防止光束漂移。 5、 具有大气激光信道与无线电信道的双信道功能。正常情况下,使用大气激光通信信道,在大雨大雾等恶劣气候下,自动转换到无线电信道,保持通信的稳定连续。

  • Applications

It can be widely used in field survey、 communication 、 national defense and military fields.

  • Characteristics

FSO is a communication mode that uses the laser to transmit information through the atmosphere. FSO equipment can transmit a variety of data, voice, image information. The system has the advantages of no electromagnetic interference, flexible network mobility, high communication reliability, good secrecy and high cost effectiveness, and has wide application prospect. Compared with radio communication, FSO is excellent at these aspects : without diverting  any  radio frequency resources,  good electromagnetic compatibility, strong ability of anti electromagnetic interference,  No interfere  other transmitting equipment, and strong confidentiality.  The system has the advantages of easy to install, easy to use, it is suitable for work in a place special topography and where wired communication is difficult to work and meet high mobility requirements. Compared with the optical fiber communication, FSO communication has a flexible and efficient network construction, operational safety, can not easily be tapped, can be moved and upgrade, etc.  Thus, FSO can greatly improve the communication capacity of optical communication system.

Gemming Laser Co., Ltd  international cooperation together with Russia laser  expert, developed several advanced FSO equipment, with technical indicators leading international, high reliability, high cost effectiveness and so on.

  • Parameters

1. Very high transmission rate , up to 10Gbit /s

2. maximum communication distance up to 7km, Double-channel ensures7km of link distance even in case of bad weather .

3.Minimum laser beam divergence angle of 0.2mard. Effectively block other signal effects

4. A fast automatic tracking system (ATP), It can effectively prevent the beam drift

5.Double channel function with FSO and radio channels. In normal circumstances, using FSO channel;But in heavy fog or  other bad weather,automatically switching to the radio channel so that to maintain the stability of communications.

1、 具有目前快速的信息传输速率,高达10Gbit /s。 2、 最大通信距离达7KM,双信道保证在恶劣天气情况下也能达到7KM。 3、 最小激光束散角0.2mard。有效阻止其它信号影响。 4、 具有快速自动跟踪系统(ATP),能有效防止光束漂移。 5、 具有大气激光信道与无线电信道的双信道功能。正常情况下,使用大气激光通信信道,在大雨大雾等恶劣气候下,自动转换到无线电信道,保持通信的稳定连续。
