Get Reel Before You Install!
It’s obvious why you might want to test reel of cable before you commit your time and resources to installing it. While it would be nice to think that every reel of cable coming out of the factory is in perfect condition, that’s not always the case. Furthermore, what’s not to say that the reel wasn’t damaged during shipping and handling? Just imagine testing the cable plant after installation only to find out that the cable is faulty—now that’s time and money lost!

Electromagnetic Interference Mitigation in Industrial Ethernet Cabling
While standard and Industrial installations of Ethernet share many of the same characteristics, such as frame sizes, signal levels and data rates, there are significant differences as well. One of these is the physical environment in which the cabling system operates.

Industrial Ethernet vs. 商务
We all know that Ethernet is the de facto physical layer communication protocol for data transmission between devices in a local area or wide area network. It has evolved over the years to deliver higher levels of performance while maintaining backwards compatibility, reliability and relatively low cost, which is why it has maintained its popularity.

Testing Plug-Terminated Links—Internationally
The Modular Plug Terminated Link, or MPTL, where a horizontal cable run terminated on one end to an RJ-45 plug connects directly into a device, has become increasingly popular for connecting a variety of devices—from wireless access points and security cameras, to PoE lights and video displays—essentially wherever it’s deemed impractical or unsafe to deploy an outlet and equipment cord.

深入了解工业以太网电缆
Last month, we published a blog about the various industrial Ethernet connectors including M-series and some new small form factor connectors like the iX and emerging single-pair Ethernet connectors. But what good is a connector designed to withstand the industrial environment without a cable that offers the same protection?

工业以太网电缆问题 - MICE
工业以太网对数据帧(有时称为数据包)丢失或损坏造成的延迟非常敏感。哪怕只有少量数据包丢失或损坏也会导致机器停机。上述问题通常是间歇性的，可能是由恶劣的工业环境造成的。工业以太网对数据帧(有时称为数据包)丢失或损坏造成的延迟非常敏感。哪怕只有少量数据包丢失或损坏也会导致机器停机。上述问题通常是间歇性的，可能是由恶劣的工业环境造成的。
