Low smoke zero halogen (hereafter referred to as LSZH but also called LSOH, LS0H, LSFH or OHLS) is a material classification that is common to cable and wire casings. When exposed to flames and high levels of heat, LSZH materials produce very little visible smoke (compared to PVC and other similar materials) and no halogens, which can be harmful to humans. There are...

Power over Ethernet (PoE) is a technology for wired local area networks that allows the electrical current necessary for the operation of each device to be carried by the data cables rather than by power cords. Doing so minimizes the number of wires that must be strung in order to install the network. PoE was originally developed in 2003 to support devices like Wi-Fi access...

Test on gases evolved during combustion This test procedure provides information if the insulation material of the cable sheath creates corrosive gases in the event of fire. Halogen parts or other material in small quantities can be easily identified with this test due to the strong change of pH and conductivity. The conductivity is <...

Like a shield used during battle, shielding in cables acts as a barrier that protects the cable from external threats, such as electrical interference (EMI). It also prevents cable signals from interfering with surrounding cables and equipment. While not all environments demand such a robust cable, shielding is becoming more common. When it first became available,...

What is a Wireless Access Point? Wireless Access Points (WAP’s) are, indeed, part of your network infrastructure. These devices allow your wireless devices (laptops, tablets, smartphones, etc.) to connect to the physically wired / cabled portion of your I.T. network infrastructure. WiFi access points are the bridge between your wireless network devices and your wired...

SFP stands for “small form-factor pluggable” and transceiver means a device that can both transmit and receive data. This article “SFP Transceivers Explained” is intended to describe all about SFP transceivers in detail that could help network professionals understand about SFP optics and its types. The SFP transceiver is a compact, hot-swappable device that plugs into a...

In the era of information explosion, almost everyone can get access to the Internet, and almost everywhere is loaded with the network cable. But you may be unaware of the fact that Cat5e/Cat6/Cat6a/Cat7 Ethernet network cables, though look like the same, actually are totally different. Here, this post will focus on Cat5e vs Cat6 vs Cat6a vs Cat7. May it help with your...

Emerging demand of higher bandwidth and faster speed connections has significantly enhanced the growth of fiber optic cable assemblies market over the past several years, especially the single mode fiber (SMF) and multimode fiber cable (MMF). However, though these two types of fiber optic cables are widely used in diverse applications, the problem—single mode vs multimode...

Wi-Fi standards decide the speed and range of a Wi-Fi network. Generally later standards are backward compatible with earlier ones. 802.11b: This was the first commercialized wireless standard. It offers a top speed of 11 Mbps and operates only on the 2.4 GHz frequency band. The standard was first available in 1999 and is now totally obsolete; 802.11b clients,...
