Using Pre-terminated Cat6 Cable For Signal Extension

Thanks to the complexity of the fiber optic installation and audio video system, the need for sending multiple signal types and control over long distances has increasingly become intense. Ethernet cables like Cat 5e, Cat 6 and Cat 7, is an indispensable component for home or small business. Nowadays most manufacturers will recommend the use of solid shielded Cat 6 cable with shielded connectors other than using the HDBASE-T chipset for signal extension. This type of cable can be terminated in the field or purchased in specific lengths already terminated….

Managed Switch VS. Unmanaged Switch: Which to Choose?

Switches are devices used in connecting multiple devices together on a Local Area Network (LAN). In terms of networking, the switch would serve as a controller, which allows the various devices to share information. Switches can be used in the home, a small office or at a location where multiple machines need to be hooked up. There are two basic kinds of switches: managed switches and unmanaged switches. The key difference between them lies in the fact that a managed switch can be configured and it can prioritize LAN traffic…

How to Understand PoE and PoE+ Switches

Power-over-Ethernet (PoE) is the technology that allows network switches to transmit power and data through an Ethernet cable at the same time. PoE switch streamlines both of the processes of powering and providing data to the device, which makes it a straightforward and reliable device for home network and small enterprise application. This article describes two types of PoE (PoE and PoE+) that are commonly used and provides information on what types of PoE can be used according to different applications. PoE Versus non-PoE Technology Power over Ethernet technology facilitates…

Why Choose PoE Switch for Your Network?

PoE is a technology which enables electrical power to pass over Ethernet cable at distances up to 100m. It is developed to reduce the cost of network planning, cabling and installation. PoE is primarily used for low-powered terminal devices, typically VoIP phones, IP cameras and wireless access points, but it can also provide a redundant power supply for switches to increase the network’s reliability. Until recently, the PoE switches are commonly found in industrial Ethernet network deployments. 802.3af and 802.3at PoE Standards The IEEE is responsible for creating PoE standards….
