Traditional networks may seem adequate, but the exponential growth of data transfer is putting traditional campus networks to the test. In short, copper wiring limits speed and distance – and both are critical for an effective campus network. Copper only offers transmission speeds up to 1Gbps and reach of 100 meters; it will suffer signal losses and tremendous data slowdowns if they go beyond. Additional investment such as signal boosters or recabling are needed to maintain network performance if the site is particularly large.
Siemon has expanded its Ruggedized Infrastructure Solutions line with new Category 6A shielded cable assemblies that feature thermoplastic elastomer (TPE) jacketing with superior resistance to moisture, sunlight, temperature, abrasion, and oil and chemicals while offering enhanced flexibility to meet the demand for connecting devices in harsher environments beyond the commercial office environment.
When it comes to high speed communication links within data centers or other business networks, demand for 10G Ethernet (10GbE) continues to grow. With plenty of options in existence, including 10G SFP+ direct attach copper cables (DAC), individual SFP+ optical transceivers and 10G copper modules, how is a network operator to choose? In this blog, we give you the top three reasons why 10G copper transceivers could provide the performance upgrade you need in a cost-effective manner.
Whenever Category 6A UTP cables capable of supporting 10 Gig applications are combed or tightly bundled, you risk increased alien crosstalk (AXT) that can wreak havoc on high speed transmission. Why? Alien crosstalk is caused by interference on a cable pair from a pair in an adjacent cable, and it became an issue with Category 6A cabling characterized up to 500 MHz simply due to the higher level of frequency and noise. So it’s easy to understand that anytime cables are evenly combed or tightly bundled together so that they lay adjacent to one another, alien crosstalk will increase—precisely why worst-case alien crosstalk testing involves six around one.
Buying Ethernet cable is not always as easy as it might seem. There is a huge selection of network cables of different types; Cat 5, Cat5e, Cat 6, Cat 6e and Cat 7, as well as different lengths colors and the like. It is important to buy the right network cable: over-specify it and you will pay too much; under-specify it and the performance will be impaired and the local area network or Ethernet link will not work as well as it might.
Belden is extending its award-winning REVConnect connectivity line to include entire end-to-end cabling systems. Applications include emerging wireless and Power over Ethernet (PoE) requirements, such as next-gen wireless access points and in-building small cells.
If you have shopped for Ethernet data cabling recently, you have probably noticed what appears to be a good value in what is known as Copper Clad Aluminum or CCA cable. But be forewarned. It it sounds too good to be true, it probably is. CCA cable is not approved for Ethernet networking usage by any regulatory body.
New 5-pole M8 (Pico) quick-disconnect cables from AutomationDirect.com are available with axial or right-angle female connectors and pigtail wiring in 1.5, 5 and 10 meter cable lengths. The quick-disconnect cables have a 3, 4 or 5-socket M8 female connector on one end and 3, 4 or 5 open leads on the other end to provide fast and easy connection between field devices and terminal connections. A “lock in place” nickel plated brass or zinc coupling nut resists high levels of shock and vibration.
In a perfect world, all network devices would be located within the standard 100-meter run length, But design and budget constraints don’t always allow for that, and there are instances when data transmission does need to exceed 100 meters. Lately, there has been quite a bit of attention surrounding cable products that claim to support data and Power over Ethernet (PoE) to distances far beyond the standard length. Do they merit the attention, and do they represent good network design practices?
Network and cabling professionals are likely to come across different Ethernet cabling standards over the course of their career. These range from legacy installs of CAT3 and CAT5e — to the modern ultra-high-performance data center CAT8 standard. Yet, for most access-layer installs, CAT6 and CAT6A are the two most common standards to choose from. This cabling will be responsible for connecting end devices such as PC’s, laptops, WiFi access points and a plethora of Internet of Things (IoT) devices.
