Triaxial, or triax cable for short, is used in similar applications to coaxial cables. Because they are designed with three conductors versus two in coax and feature an extra layer of shielding and insulation, they are generally more costly. This extra shielding provides ground and is more resistant to EMI than coax designs because it […]
What are cable glands?
Cable glands are devices that are critical when terminating cables in hazardous or harsh environments, where ingress protection, sealing and grounding is necessary to safely pass a cable, wire or tube through an enclosure. They provide strain relief and are also designed to contain electrical sparks or flames that may occur in hazardous environments. Additionally, […]
What is wire ampacity?
When selecting a cable, one must know its wire ampacity rating. This rating has been determined by the NEC (National Electrical Code), which lists ampacity ratings for real-life installation examples. Most cable manufacturers provide ampacity tables on their websites. Other organizations that supply ampacity tables include IEEE (Institute of Electrical and Electronics Engineers), which offers […]
How are high-speed copper wires terminated today?
In our last blog post, we discussed traditional methods of terminating high-speed copper wires. In today’s discussion, we’ll highlight how these processes have modernized in recent years, starting with hot bar solder reflowing. Hot Bar solder reflowing evolved for use through an upper and lower wide opposite bar machine that did simultaneous reflowing of twin-axial wire […]
What is the traditional process for high-speed copper wire termination?
Many electronic generations ago, during the 1970s, high-speed I/O copper connector popular types included coaxial BNC, pin-and-socket D-subminiature, and even a bit later the IDC Delta-ribbon varieties. Many cable assemblies were hand terminated by highly skilled manufacturing assemblers and technicians. In those days, accurate hand tools helped to generate a reasonable yield and rework level. […]
What are the temperature limitations of plastic cable carriers?
Many types of plastic are used in cable management systems, but the most common standard plastic that most people use is glass-filled nylon or nylon six. This material is best suited to applications that range in temperatures from –40° to 240°F on the high end. However, this operating temperature range can be increased by using […]
Where are network copper breakout cable assemblies and related connectors used?
Breakout cable assemblies are also called Fan-out, Hydra and Octopus cables depending on what market segment and application history is involved. The name Hydra is used by those in the enterprise infrastructure interconnect industry. Breakout is the term favored by many Cloud datacenter people. Fan-out has been mostly used by enterprise datacenter people and Octopus […]
Coaxial cable: Where to use?
A coaxial cable has inner conductors surrounded by several insulating layers. A conducting shield and jacket are then wrapped around the insulation layers to prevent signal interference such as EMI. A coaxial cable differs from other shielded cables used for carrying lower-frequency signals. In other words, they are used in almost every single home for […]
When should you use flat cables?
If extreme flexing and tight designs are part of your application, flat cables may be the route you need to go. There are three types of flat cables that are most commonly used. Extruded Flexx-Sil, Polytetrafluoroethylene (PTFE) and molded flat cables. All three of these types are used in place of round cables for easy […]
What’s going on with the new RCx high speed IO passive copper cabling?
RCx, Rack Connect x(lane), is a new intra-rack passive copper short reach, 25 Gbps per lane cabling system that is being driven and supported by a group of next generation Cloud interconnect developers. The 25Gigabit Ethernet Consortium, Ethernet Alliance and soon, maybe other IO interface groups, are supporting RCx which connects ToR or MoR […]
