XX 项目综合布线保密性与带宽及安全性要求比较高,设计开始对建设光纤到桌面网络有很高的需求。 Due to the relatively high requirements for confidentiality, bandwidth, and security of the comprehensive wiring of the XX project, the design began to have a high demand for the construction of fiber-to-the-desktop networks. 传输速率 的提高,其 电磁泄漏 的风险也快速上升,这对信息安全有较高要求的单位来说无疑是最有吸引力的。 Compared with cables, optical fibers can provide higher bandwidth, longer transmission distances, and longer working life. In particular, optical fibers will not behave like cables. As the transmission rate increases, the risk of electromagnetic leakage also rises rapidly. This is undoubtedly the most attractive for organizations with higher requirements for information security.

方案优势 5. Solution advantages

FTTD FiberToTheDesktop )是指光纤替代传统的铜缆传输介质直接延伸至用户终端电脑,使用户终端全程通过光纤实现网络接入。 Fiber to the desktop FTTD ( FiberToTheDesktop ) refers to the replacement of traditional copper cable transmission media directly to the user terminal computer, so that the user terminal through the fiber to achieve network access. PoE 以太网技术等特点,在工作区子系统中仍然处于统治地位。 Copper cable system is still dominant in the work area subsystem due to its low cost, simple installation and construction, convenient maintenance, and support for PoE Ethernet technology. However, with the development of optical communication technology, the bottleneck of copper cable system upgrade and the complexity of the application environment, the advantages of optical fiber become more and more obvious:

1 )光纤可支持更远距离、更高带宽的传输。 ( 1 ) Fiber can support longer distance and higher bandwidth transmission. OM4 多模光缆在 850nm 波长提供至少 4700MHz km 的有效模式带宽、 3500MHz km 的注入模式带宽,在 1300nm 波长提供至少 500MHz km 的注入模式带宽,都支持最长 550m 10Gbps 串行传输,以及 150m 以上的 40/100Gbps 传输。 The new generation of OM4 multimode optical cable provides at least 4700MHz km effective mode bandwidth at 850nm wavelength, 3500MHz km injection mode bandwidth, and at least 500MHz km injection mode bandwidth at 1300nm wavelength , all support 10Gbps serial up to 550m Transmission, and 40 / 100Gbps transmission over 150m . OS2 单模光缆在万兆的以太网中,最长甚至可以达到 40 公里的传输。 The Zero Water Peak OS2 single-mode optical cable can transmit up to 40 kilometers in 10 Gigabit Ethernet . These are simply not possible with copper cable systems. 100 米,选择铜缆系统布线,必须要增加区域管理间,增加网络设备和布线材料,这都会导致项目工程成本增加,并且,还有可能增加链路故障点。 When the transmission distance of information points exceeds 100 meters, the selection of copper cable system wiring must increase the area management room, network equipment and wiring materials, which will lead to increased project engineering costs, and may also increase link failure points. However, fiber optic systems can easily solve this problem.


2 )光纤是非金属物质,数据在光波上传输,可以避免外界的电磁干扰 EMI 和无线电频干扰 RFI ,例如在一些特殊的布线环境:空调机房、医院的医疗设备房间、机械制造工厂等;并且,纤芯之间无串扰,信号也不会对外泄露,起到了很好的保密作用,例如在一些信息要求保密的场所:公检法机关、军事行业、高科技研发单位等。 ( 2 ) Optical fiber is a non-metallic material, and data is transmitted on light waves, which can avoid external electromagnetic interference EMI and radio frequency interference RFI , such as in some special wiring environments: air-conditioning machine rooms, hospital medical equipment rooms, machinery manufacturing plants, etc .; and There is no crosstalk between the fiber cores, and the signal will not be leaked to the outside, which plays a very good role of confidentiality. For example, in some places where information is required to be kept secret: public inspection law agencies, military industries, high-tech research and development units, etc.

3 )使用环境温度范围宽;通讯不带电,可用于易燃、易暴场所,使用安全。 ( 3 ) The temperature range of the use environment is wide; the communication is not powered, and it can be used in flammable and violent places, and it is safe to use.

4 )耐化学腐蚀,使用寿命长。 ( 4 ) Chemical resistance and long service life.

5 )不同的护套材料和内部结构,可应付恶劣的办公环境。 ( 5 ) Different jacket materials and internal structures can cope with harsh office environments.

6 )铜缆系统从 Cat5 发展到 Cat6A ,在结构上增加了十字骨架、屏蔽层(甚至双层屏蔽层),线径变得越来越大,这些都无形增加了铜缆的原材料成本、运输成本、安装辅材成本、安装施工成本和测试成本等。 ( 6 ) The copper cable system has developed from Cat5 to Cat6A . The structure has added a cross skeleton, a shielding layer (even a double-layer shielding layer), and the wire diameter has become larger and larger, all of which have increased the raw material cost of the copper cable, Transportation cost, installation auxiliary material cost, installation construction cost and test cost, etc. Cat5 4 个测试参数,发展到后来十几个,现在还多了个外部串扰测试参数,使得 Cat6A 布线系统的验收测试更加的繁琐和费时。 The copper cable system has developed from four test parameters of Cat5 to more than a dozen later. Now there are more external crosstalk test parameters, making the acceptance test of Cat6A wiring system more tedious and time-consuming. 2 个:“衰减”和“长度”。 However, since the development of optical fibers has not changed in volume and weight, there are generally only two test parameters : "attenuation" and "length". In addition, with the development of optical communication technology, the cost of raw materials has tended to decrease, and installation and construction have become more and more simple.
