Use Case for 10G/40G Switch-to-Switch Interconnect

In addition to 10 GbE, the telecom market nowadays is also actively deploying 40 GbE connections to support server connectivity, the typical use case is switch-to-switch interconnects. In fact, copper cables are used in some special cases, primarily for switch-to-switch short-reach connections. However, with the majority of 40 GbE connections being optic fiber-based, fiber optic cables, especially the MTP/MPO cables…

Deciphering Male and Female RJ45 Connector

Many people think that RJ45 to RJ45 connectors are the same as the modular plugs or jacks, but they’re wrong. In most cases, the term plug technically refers to the cable or male end of the connection while the term jack refers to the port or female end. If you have had a misunderstanding about these concepts, you probably have…

Understanding Bulk Ethernet Cable: Stranded or Solid Ethernet Cable

There are a dizzying number of Ethernet cable type available on the market, corresponding to an array of standards detailing the configuration and performance specification needed to support the increasingly faster data rates and larger bandwidths of incoming technologies. Of which stranded and solid Ethernet cables are the commonly used cable types when purchasing bulk Ethernet cable. These two different…

The figure shows the Cat5e RJ45 inline coupler (orange). This Cat5e RJ45 Coupler offers a practical, cost-effective solution for joining two RJ45-terminated cables together to form one long cable.

Inline Coupler vs. Punch Down Keystone Jack

When DIY a home network, besides the common problems (written in the previous article “Do It Yourself for Your Home Network”), people often feel puzzled about what I should use for my jacks—inline coupler or punch down keystone jack. The first one is easy to install but adds an extra connection to the network. The last one is cheaper and…
