布线发展史

免费线缆测试管理软件 – 收获 LinkWare™ 带来的好处

如今,测试先进布线设备非常复杂,仅一个 5e 类测试报告就包括超过 400 个数据字段。由于一般的作业就包括几百条甚至几千条链路,即使网络工程师检查了所有结果并确定结果都合格,但关键性的问题依然存在:您如何判断是否使用了一个不正确的测试规格或错误的适配器呢?是否所有的测试仪都使用了正确的软件?您是否得到了预期的余量并且它们是否一致?

如何通过环型通量提高多模测试准确性

测试过多模光纤链路的人都应该了解,如果使用不同设备供应商提供的不同光源,最终得到的损耗值的浮动性高达50%。若未进行适当控制,则多模光源会以不同的方式将光注入多模光纤。  即使采用同一制造商生产的光源,但在不同的发射条件下也会产生不同的链路损耗测量结果,最终出现不同的 — 并且通常令人困惑的 — 测试结果。

不同类型的光源会有不同的发射条件。例如:发光二极管 (LED) 会使多模光纤过多填充模式组,而激光又未使光纤填充足够的模式组。Overfilling tends to produce link-loss measurements that are inappropriately high and under filling tends to generate loss measurements that are optimistic in regards to the loss that will occur in the cabling once it is operational. 

这些有缺陷的结果最终会影响布线基础设施的性能,并且会造成数据中心和其它依靠光纤布线连接组件的环境方面的严重问题。

Co-location Data Center Operators Testing Next Generation Cabling.

I recently had occasion to visit with several individuals from a high growth sub segment of our industry. Co-location data centers enable organizations to rent equipment space and bandwidth.

OTDR Troubleshooting in the Data Center? ...Yes we can!

The growing demand for higher bandwidth is affecting nearly every industry today, as organizations rely more on applications that support a variety of critical business processes. Whether it’s high-definition video, social media support, electronic medical records or other high-bandwidth applications, companies increasingly are facing a need to support higher capacity data transmission for their employees, customers and business partners. This trend toward greater capacity has in turn created an increased need for high bandwidth fiber optic cabling in the data center.

环形通量 —它是什么?为什么需要关注?

随着 LC/MPO 盒之类低损耗光纤组件的推广应用,损耗预算(测试限制)变得越来越小。这样一来,安装商会发现以前进行光线测试的方法和假设不再适用。

虽然电信工业协会 (TIA) 依旧允许每个连接器的衰减为 0.75 dB,但工厂抛光连接器的衰减接近 0.2 dB。因此,在测试 TIA 极限值时,安装商面对诸多的不确定性。换句话说,他们的测试实践需要合理化,而不求完美。

Finding the keys to success in the MPO datacenter

当所有公司都在为了支持日益庞大的业务程序解决 IP 流量需求的激增问题时,许多公司正在利用光纤网络设计各自的数据中心,以支持服务器、交换机和存储区域网络之间 10G 或 40G 以太网连接,以及用于核心交换的 100G 以太网和路由主干连接。

在 2012 年 5 月召开的 Interop 2012 会议上,以太网联盟作为致力于改进以太网技术的全球联盟,主办了一项互操作性演示,重点介绍了 10G 和 40G 以太网无缝互操作性。它宣称这项功能可使以太网“具备独特的性能以支持数据中心的云计算、汇聚和虚拟化。”

LinkWare 7 –A good thing just got a lot better!

What do Albert Einstein and Michael Jordan have in common?  No, they’re not both LinkWare users… They focused on continuously learning and pushing the envelope even though they were already far ahead of everybody else. Just like our engineers who worked tirelessly to rebuild LinkWare from the ground up and make the best even better. Improvements include:

This one is for the ages! New OTDR redefines enterprise fiber testing.

By now you will have heard about the new OptiFiber Pro OTDR  and that’s a relief for me because I’ve been biting my tongue for a while!  Now that its been announced, let me share my impressions and an overview of what makes the product unique.  I will also include some links to more detailed information.  Take this from a guy that has spent five of the last seven years playing with OTDRs… I’ve used them all.  And this one is going to change everything!
