Simulating MIMO connections.

Anritsu Corporation has introduced a newly developed Butler Matrix 4x4 (0.6 GHz to 7.125 GHz) MA8114A to expand its Butler Matrix module lineup of simulating MIMO connections.

The MA8114A is a Butler Matrix transmission path with 4 input and 4 output ports and supports the 6 GHz band (5.925 GHz to 7.125 GHz), which is not supported by the existing Azimuth STACSIM-WB-(Static Channel Simulator) (ACC-339) used for evaluating 4x4 MIMO throughput of LTE/5G base stations and Wi-Fi devices. The MA8114A helps users to build a stable 5G/W-Fi evaluation environment, and efficiently test throughput.

Development Background.
LTE/5G Base station and Wi-Fi device vendors use the Over The Air test environment to evaluate the maximum throughput with 4x4 MIMO for their products. This entails measuring the Tx/Rx radio performance of wireless devices using an anechoic or OTA chamber which is designed to block external radio waves. Because the transmission environment varies depending on the distance to the User Equipment (UE), a drawback of this approach is its low reproducibility of measurement results. While reproducibility can be improved by connecting the two devices using an RF cable, a simple coupler cannot simulate the MIMO transmission environment. The MA8114A solves this issue, ensuring highly reproducible measurements.

The upper-limit frequency for NR FR1 has been extended beginning with 3GPP Release 17, and the 6 GHz band has been added to Wi-Fi 6E/7. The MA8114A supports a frequency range up to 7.125 GHz in preparation for countries launching services on new frequency bands.

The product lineup of the Butler Matrix module also includes the Butler Matrix 8x8 (0.6 GHz to 7.125 GHz) MA8118A with 8 input and 8 output ports, which supports a frequency range up to 7.125 GHz as well. The MA8118A can be used not only for 8x8 MIMO throughput evaluation but also to enable efficient testing of devices having multiple RF ports.

Is fibre right for your industrial network?

Henry Martel*, Field Application Engineer with Antaira Technologies, discusses fibre cable types and costs

In the rapidly evolving landscape of industrial IoT networks, understanding the intricacies of fibre optic cables is essential for IT technicians and plant management alike.

Although fibre has been deployed for more than four decades, several misconceptions remain. At the top of the list is that installing fibre optics is more expensive than copper due to its networking devices, terminations, and cables. Another is that fibre is harder to install and terminate than copper. Last, there’s the fallacy that fibre cables are fragile since they're “made of glass”. We’ll dispel those lingering myths here.

Fibre optic cables are now the fastest-growing transmission medium for both new network builds and expansions, especially in applications that require high bandwidth, long distances, and immunity to electrical interference. Network backbones transmitting huge amounts of bandwidth-consuming data files almost exclusively rely on fibre.

So, is fibre right for your industrial network? Let’s find out.

Fibre Optic cable construction.
As the name implies, fibre optic cables carry optical signals using fast-traveling pulses of light instead of electricity over long distances. At the cable’s core are extremely pure glass fibres the same width as human hair that transmit light photons down the length of cable.

10-Port Industrial PoE+ Light Layer 
3 Gigabit managed Ethernet switch.
A 125µm layer of glass cladding surrounds the core to guarantee that light is reflected, rather than leaking out at the edges, therefore enabling the signal to travel longer distances without attenuation. Over the cladding is a buffer that keeps the cable's internal glass structure safe from damage and discourages excessive bending. An additional layer of reinforcing fibres shields the core, followed by a rugged plastic jacket.

Durability of fibre cables.
fibre is far from fragile. The strength members of fibre cables provide protection against crushing blows, bending forces and, of course, the pulling tension encountered during installation. Reinforcing around the core keeps the cable stiff to maintain the allowable cable-bend radius and prevent kinking when pulling around corners. Once installed, fibre optic cables are sturdier than copper with fewer parts. In fact, a fibre optic cable can last up to 50 years, withstanding extreme temperatures, high shock, moisture and vibration without degrading.

All this doesn’t mean careless installation won’t damage fibre optic cables. Exceeding bending radius limits or kinking the cable will lead to micro-cracks that increase the potential for degradation. Poorly spliced cable will give rise to fibre movement if splice materials have different characteristics than the cable, such as different thermal expansion coefficients. Malfunctions in fibre optic networks are virtually always due to poor installation, misaligned fusions, or accidental cuts.

Despite the built-in mechanical protection in modern fiber optic cables, some industrial or outdoor plant installations require more protection. In these instances, armored cables are recommended.

Armored fibre optic cables are manufactured to handle abrasion, impact, UV damage and are designed for underground direct burial out of the box. Armored cables can be a cost-effective alternative to running the cable through protective conduit. Conduit installation costs are incurred twice: first, when installing the conduit and second, when installing the cables, hence doubling labor and material costs. Armored cables cost more than standard fibre cables, but the labor to install them is considerably less.

Single-mode fibre.
Fibre optic cables are broken down into two main product categories — single-mode (SM) and multimode (MM).

Single-mode cable has a small diametral core of 9µm that permits only one mode of light to propagate. SM decreases the number of reflections created as light passes through its core, resulting in lowered attenuation and creating the ability for a signal to travel several miles before needing to be enhanced. SM is the preferred choice for long-haul networks, telcos, campus backbone and large enterprises spread over extended areas.

SM is available in two classifications:
• OS1: for use in indoor locations over shorter distances and where electrical interference may be greater.
• OS2: targeted at outdoor installations with a maximum range of 125 miles. OS2 cables support bandwidth speeds of up to 400 gigabits per second (Gbit/s) over distances up to 80km or further using off-the-shelf optical modules. OS2 is generally more tolerant to flexing and stretching than OS1. Not surprisingly, OS2 cables also tend to be more expensive than their OS1 counterparts.

Multimode fibre
Multimode (MM) fibre optic cables feature multiple strands, ranging in number from 2 to several hundred, resulting in a wider core (50µm to 62.5µm) that accommodates the transmission of numerous data streams over one cable. However, the larger core has its limitations. Due to higher signal attenuation, MM cables are unable to handle the same long distances as SM fibre cables, typically 2km or less, so they are used to connect in short range applications. MM developed with a plastic core may be used in place of glass for certain industries, such as mining or sensing applications, while bigger core diameter fibre (called MM200) is necessary in other applications.

Like SM, MM cables are split into several classifications:
• OM1: maximum bandwidth of 10 Gbit/s, 100 feet distance (obsolete in ISO/IEC 11801 and TIA 568 standards)
• OM2: maximum bandwidth of 10 Gbit/s, 260 feet distance (obsolete in ISO/IEC 11801 and TIA 568 standards)
• OM3 maximum bandwidth of 10 Gbit/s, 1000 feet distance
• OM4: capable of reaching 1300 ft at 10 Gbit/s and 40 Gbit/s up to 500 feet
• OM5: like OM4 but uses different colors of laser light to increase support for greater bandwidth up to 200 Gbit/s or even 400 Gbit/s.

MM should not be confused with “breakout” fibre optic cables. Breakout cables are essentially a group of SM or MM jacketed fibres bound together within an outer jacket. A single connector is shared at one end of the breakout cable with individual connectors on the other. Color-coded cables are "broken out” and therefore enable several connections between network devices with different speed ports, while fully utilizing port bandwidth. Consider, for instance, a switch with a 100G port connected to ten 10G ports. Ideal for patching, breakout cables simplify installation, reduce cable congestion, and improve overall cable management.

Single vs Multimode.
In the past, the general rule was MM for short indoor/same building applications while SM was for long distance links and just about everywhere else. That is changing. Recently, there’s been a big decrease in cost-per-foot for SM cables. Also, the price of SM transceivers has come down considerably, while their designs have become more resilient; in the past, an attenuator was required, or you’d risk burning out the receiver if the cable was too short for the laser used.

Both these factors have made SM more cost-efficient for indoor/ same building applications. With 40- and 100-Gbit/s connections becoming commonplace, SM increasingly makes business sense for new installations and network expansions. Single mode electronics are still about 30% more expensive than conventional electronics because they require more complex optical processors to create powerful light sources. However, when factoring in the lower costs of SM cables, the overall expense is similar — yet SM’s performance benefit is dramatically better. SM supports brighter, more powerful light sources with lower attenuation. Its bandwidth is unlimited, at least in theory. Although MM comes in five different cable grades, none of them can match SM’s limitless bandwidth over short or long distances.

Cost: Fibre vs Copper
In general, fibre remains more expensive than copper in the near term. However, fibre ends up costing less in the long run after factoring in copper’s overlooked costs, maintenance, interference, risk of tampering and replacement expense.

There is no question that installation prices for fibre are higher than those for copper due to the skill required for terminations. But as we said earlier, the cost of fibre cable, hardware, and components is declining. In addition, fibre usually requires less than half the networking hardware, has significantly less downtime, and is less expensive to scale and maintain.

Another big plus is that fibre optic cables are immune to electrical noise. Produced by motors, relays, welders, and other industrial equipment, electrical noise can seriously interfere with copper cabling. The more distance that copper cabling travels between two points, the more noise it absorbs and the more the signal deteriorates. Data is also more secure with fibre since it does not radiate signals and is nearly impossible to tap, thwarting a potentially expensive cyber-attack. Importantly, fibre makes upgrading unnecessary as network speeds and requirements escalate.

Installed “first costs” have long been the driving force behind selecting a cabling medium. Frequently, these costs become the reason users choose to deploy copper instead of fibre. But with the price of industrial fibre networks rapidly dropping due to the factors described above, there are now both short- and long-term benefits that make fibre a more compelling choice. Fibre termination.
Many technicians fear that installing fibre connectors on bulk fibre requires a high level of skill to be done correctly. Several years ago, this was true, but today it is not always the case. The old school way involved solvent glue, lots of small pieces, and hand polishing the tip. Besides being difficult and time-consuming, the precision required by this method led to unacceptable levels of light loss and back reflection when performed by a less experienced technician.

Today there are better ways to terminate bulk fibre like using pre-polished connectors, fusion or mechanical splicing, and fibre optic pigtails allowing successful implementation even for beginners. Network technicians can choose the best termination option for their needs by weighing the benefits of each technique. Of course, they can also order factory pre-terminated fibre optic cables in the lengths needed that have already been tested for plug-and-play deployment. That said, field termination or “on-site” termination requires a trained technician adhering to industry standards and using specialized tools. The same goes for splicing broken or severed fibre cables to maintain network integrity.

Like any network technology, fibre terminations are not immune to problems even when performed by a professional. Once a termination is complete, the optical signal must be tested to ensure proper connectivity. Routine troubleshooting will help identify any underlying issues without interrupting network service. Contamination of connector end-faces by dust, dirt and oil is one of the primary causes for signal loss and failure. Poor polishing or incorrect alignment of fibres can also result in signal loss, as can exposure to excessive humidity or caustic chemicals.

Prototyping of End-to-end AI Accelerated Vision Applications.

BitFlow has successfully integrated the unprecedented computing power of the NVIDIA® Jetson AGX Orin module, which can perform 275 trillion operations per second (TOPS), with the lightning-fast data rates of its CoaXPress (CXP) frame grabbers.

When combined with the NVIDIA AGX Orin Developer Kit, this cost-effective platform empowers engineers to prototype complex machine vision and autonomous inspection applications, leveraging AI accelerated image processing while simultaneously supporting up to four CoaXPress (CXP) cameras and multiple concurrent AI application pipelines. Groundbreaking new applications are more easily developed that augment rule-based machine vision with image-based analysis, making it possible to move beyond “pass/fail” to tasks like image classification, image segmentation, and object detection.

Once proof-of-concept is established, a production model can move forward utilizing an Advantech AIR-030 AI Inference System Box featuring PCI Express x16 and based on the NVIDIA Jetson AGX Orin. As a result of this innovation, Time to Market and associated development costs are significantly reduced.

50GB Data Transfer. BitFlow CXP frame grabbers connect directly to the Jetson AGX Orin via a built-in x16 PCIe slot. Image data may then be transferred at speeds up to 50GB per second from CXP cameras to the NVIDIA Ampere GPU architecture — much faster than what NVIDIA Jetson users are typically limited to using USB3 or GigE Vision cameras. BitFlow CXP frame grabbers DMA directly into the embedded GPU memory for image capture, pre-processing, and machine learning inference, shifting the load from the host computer to avoid CPU overhead.

Besides faster transfer speeds, the CoaXPress interface allows a single cable to carry all data, control, triggering, and up to 13W of power to connected cameras at lengths as far as 100 meters. CoaXPress eliminates the need for multiple cables and a local power supply, therefore giving the system integrator far more flexibility for their prototype designs.

Seamless integration between the NVIDIA Jetson AGX Orin and BitFlow frame grabbers is achieved through BitFlow’s Linux AArch64 SDK. With the SDK being universal, not only is BitFlow's full line of CXP frame grabbers (Cyton and Claxon families) supported, but additionally the BitFlow Axion Camera Link family is an option for customers.
