In last week’s blog, we took a Closer Look at 40 Gig Duplex Multimode Applications, just one of the many ways that today’s data centers are cost-effectively achieving increased bandwidth in switch-to-switch fiber links. And when we say many ways, we literally mean many.
If you take a look at network application standards for balanced twisted-pair cable, there’s not that many to be concerned with. Sure, we had a methodical shift from 10BASE-T, to 100BASE-T, to 1000BASE-T, to 10GBASE-T that then jumped back to 2.5GBASE-T and 5GBASE-T to accommodate new technologies over the installed base and then forward again to the upcoming 25GBASE-T and 40GBASE-T standards, but all of this is nothing compared to fiber. And unlike fiber, there are few, if any, non-standard ways of deploying copper cabling.

There’s been a lot of talk in the industry surrounding solutions capable of running 40 Gig Ethernet over duplex multimode fiber—especially with OM5 wideband multimode fiber (WBMMF) now recognized within industry standards that specifies wavelengths between 840 and 953 nanometers to support wave division multiplexing (WDM).

By now you’ve probably heard of 8-fiber MPO plug and play solutions available on the market, which are ideal for Gigabit (40GBASE-SR4) and 100 Gigabit (100GBASESR4) applications that use 8 fibers with 4 transmitting and 4 receiving at either 10 or 25 Gb/s. Unlike 12-fiber MPO solutions where 4 of the 12 fibers go unused, 8-fiber MPO solutions offer 100% fiber utilization in these applications. But did you know that when looking ahead to future fiber applications, 8-fiber MPO solutions continue to make the most sense? That’s because all future duplex, parallel optic and WDM-based fiber applications are divisible by either 2 or 8 fibers – not 12.
Born in the 1970s, Ethernet technology has continually evolved in order to meet the never-ending requirement for faster rates of data transmission. Through this ongoing evolution, it has matured into the foremost technology standard for local area networks (LANs) as newer, higher performing iterations, such as 1 Gigabit Ethernet and 10 Gigabit Ethernet. There is a variety of types of cables available for making Ethernet connections at speeds of 1 Gigabit and 10 Gigabit per second. This paper provides a brief introduction to these two types of high speed Ethernet cabling solution, 1 Gigabit Ethernet cabling and 10 Gigabit Ethernet cabling.
The logical alternative is to install a fiber-based distribution network that can handle speeds well beyond 1 Gbps, that is, Fiber-To-The-Desktop (FTTD). For the FTTD, you have to choose the best optical technologies: Gigabit Passive Optical Network (GPON) based optical technologies. This blog introduces the concept of using GPON for FTTD applications to serve the needs of the modern-day business.

In recent years, 40 Gigabit Ethernet (GbE) has gained more popularity and the market of 40GbE is encouraging. But with the rapid growth of the new standard 100GbE, a new voice is announcing, namely 25GbE. As the increasing bandwidth requirements of private and public cloud data centers and communication service providers, 25GbE will to have a significant impact on server interconnect interfaces. Now you have two upgrade paths to 100G, 10G-25G-100G and 10G-40G-100G. Which one to choose? This post will make a comparison of 25GbE and 40GbE cabling, hoping it can help you make an appropriate decision.
Data center interconnects multimode vs. single modeAngelina Li
The rapid growth in storage and computing services is driving an expansion in both the physical size
and overall computing power of the modern data center. This high-speed data interconnects linking

10 Gigabit Ethernet Technology
Description: This presentation shows the use of 10 Gigabit Ethernet Technology
10 Gigabit Ethernet (10GE, 10GbE, or 10 GigE) is a group of computer networking technologies for transmitting Ethernet frames at a rate of 10 gigabits per second. It was first defined by the IEEE 802.3ae-2002 standard. Unlike previous Ethernet standards, 10 Gigabit Ethernet defines only full-duplex point-to-point links which are generally connected by network switches; shared-medium CSMA/CD operation has not been carried over from the previous generations Ethernet standards[1] so half-duplex operation and repeater hubs do not exist in 10GbE.

Ethernet as the networking standards, enables computers to locally connect to each other, which is
the ultra-strong backbone to the many networks we use every day. Although most of the Ethernet
market is still running around 1 Gbqs or 10 Gbqs, there is a strong interest in higher data rates.

Two main media options are available for 10GbE interconnect: copper and fiber optics, including 10GBASE-CX4, SFP+ DAC, 10GBASE-T, 10GBASE-SR, 10GBASE-LR, 10GBASE-ER, 10GBASE-ZR, and so on.
25G Ethernet, developed by IEEE 802.3 task force P802.3by is a newly proposed standard for Ethernet connectivity. After its appearance, the road to 100G is considered to be 10G→25G→100G. 25G Ethernet may be the quickest path to completion IEEE Ethernet standards effort to 100GbE. To unveil the mask of the mysterious 25G standard, this post offers some answers to help you sort it out.
Fiber media converter is a cost-effective solution to this issue. It dramatically increases the bandwidth and transmission distance of the local area network (LAN) by allowing the use of fiber and integrating new equipment into existing cabling infrastructure.
The QSFP+ optical transceiver is the dominant transceiver form factor used for 40 Gigabit Ethernet applications. In the year of 2010, the IEEE standard 802.3ba released several 40-Gbps based solutions, including a 40GBASE-SR4 parallel optics solution for multimode fiber. Since then, several other 40G interfaces have been released, including 40GBASE-CSR4, which is similar to 40GBASE-SR4 but extends the distance capabilities.
ISO/IEC 14763-3 edition 2 was published in 2014. This standard supports the implementation and operation of customer premises cabling by specifying systems and methods for inspecting and testing optical fiber cabling. In 2015, a corrigendum was published. Currently, an amendment is under review to make further corrections. Also, a supplement to the amendment was added.
The corrigendum made changes to connecting hardware attenuation values and modified the equations for test limits. The amendment made corrections to end face inspection, test methods, and uncertainty. The supplement to the amendment fixed errors within the uncertainties. Details of the changes are described herein.
Cable testing 101 how to read the link ware™ pc reportsmithponting
The section just below the blue area on your report shows the wire map test and a boxed-out area with critical values for the cable under test. These include the length (displayed in feet or meters depending on what the user selected), propagation delay, delay skew, resistance and insertion loss margin.
The detail of the insertion loss margin can be seen in the insertion loss graph to the right, and it includes the margin based on the worst pair, at what frequency and the test limit for that frequency.
Standards update the four a’s of harmonizationsmithponting
When TIA adopts an IEC standard, or vice versa, it quite literally means that they take on and follow the standard. For example, TIA adopted the IEC 61280-4-1 multimode fiber optic testing standards as TIA-526-14-C. Because TIA has an outdated singlemode fiber optic testing standard, they are also considering the adoption of IEC 61280-4-2. If they do, it will be published as TIA-526-7.
Standard update 25 gbase t joins the party!smithponting
Since the development of 40GBASE-T (IEEE 802.3bq) began a few years ago, most of us believed that the next Ethernet data center speed for twisted-pair copper cabling beyond 10 Gb/s would be 40 Gb/s.
But in November 2014, IEEE 802.3 put out a call for interest on 25GBASE-T, driven by the likes of Cisco, Microsoft and Intel who recognized 25 Gb/s as a more efficient, cost-effective option for switch-to-server speeds in cloud-based data centers. Hence the 25GBASE-T IEEE study group was formed.
Standard update 25 gbase t joins the party!smithponting
With representatives from 25 companies overwhelmingly pledging support for the formation of the 25GBASE-T study group, the likes of Microsoft, Cisco and Intel driving the party bus, and a demonstrated broad market potential, 25GBASE-T is definitely a welcomed partygoer.
Why is 25GBASE-T considered a more cost-effective step in the migration to 40GBASE-T? Not only does it support the backwards compatibility of BASE-T technology and enable equipment vendors to limit the power per port to under 3W, it can also leverage existing transceiver technology to establish a fixed migration path to 40GBASE-T over the same 30-meter channel.
Benefits of fiber optic and passive optical lan testsmithponting
Passive optical LANs are a point-to-multipoint fiber architecture that use passive optical splitters to divide the signal from one singlemode fiber into multiple fiber signals. The signals are transmitted simultaneously in both directions over separate wavelengths using wavelength division multiplexing (WDM) technology—1310nm for upstream data and 1490nm for downstream data.
By increasing the level of noise within the channel, alien crosstalk decreases signal-to-noise ratio and degrades the bandwidth capabilities of the cable, potentially preventing the cable from supporting 10 Gig transmission. This is precisely why standards bodies like TIA and BICSI, as well as most cable manufacturers, recommend letting cables have a “natural lay” in pathways and conduit. But even with this recommendation, there are still some customers that require cables to be combined in neat bundles. There are even tools available for quickly and efficiently straightening, combing and organizing cables into multiple bundles with ease.
Beat the heat with versiv™ cool featuressmithponting
San Diego hit its highest ever recorded temperature this summer, the Southwest experienced what meteorologists have dubbed the “great 2017 heat wave,” and even New Jersey’s Newark airport broke its 1973 record with a sweltering 97 degrees. Unfortunately, experts predict that the expanse of hotter-than-average temperatures will continue to grow in August—from the West coast through the Plains and into parts of the Midwest and Southeast.
Alien crosstalk is a relatively new measurement that’s widely misunderstood. I’m often asked why it’s an important measurement and if it’s required to be measured by the standards. Also misunderstood is the sampling criteria for alien crosstalk measurements, which are applied so that not all links have to be tested?
Six reasons certification is essential white papersmithponting
Economic turmoil is shining a bright light on the
value of services used by IT departments. Among
them are the services used to deploy and maintain
enterprise network infrastructure. Infrastructure
includes copper and fiber cabling, and it is the
foundation of the network. This white paper identifies the
specific benefits afforded by cable certification and
how much it pays back to the network owner.
Certification vs. qualification a closer looksmithponting
Used primarily by commercial contactors and network technicians, certification testing determines if a link is compliant with a specific category or Class of cable as determined by well-defined parameters outlined in ANSI/TIA-568-C.2 or ISO/IEC standard 11801 (ed. 2). For instance, certification testing will determine if your link is compliant with Category 6 or Class EA standards.
The standards review board of the Institute of Electrical
and Electronics Engineers (IEEE) approved the standard for 10 Gigabit/sec Ethernet over twistedpair copper cabling (10GBASE-T) on June 8, 2006. This paper provides an overview of the methods to measure and certify the performance of the installed cabling system for compliance with the requirements of 10GBASE-T, as well as with the draft specifications of Augmented Cat 6 (Cat 6A) or Augmented Class E (Class EA).
101 series understanding copper cabling’s balancing actsmithponting
You have likely heard copper network cabling referred to as balanced twisted-pair copper cabling, and maybe you’ve heard of the testing parameter referred to as DC resistance unbalance. But what does all this balance-related terminology really mean, and why should you care?

Elevating Tactical DDD Patterns Through Object CalisthenicsDorra BARTAGUIZ
After immersing yourself in the blue book and its red counterpart, attending DDD-focused conferences, and applying tactical patterns, you're left with a crucial question: How do I ensure my design is effective? Tactical patterns within Domain-Driven Design (DDD) serve as guiding principles for creating clear and manageable domain models. However, achieving success with these patterns requires additional guidance. Interestingly, we've observed that a set of constraints initially designed for training purposes remarkably aligns with effective pattern implementation, offering a more ‘mechanical’ approach. Let's explore together how Object Calisthenics can elevate the design of your tactical DDD patterns, offering concrete help for those venturing into DDD for the first time!

2. How High-Speed Fiber Applications is impacting the Networking Arena?
20-11-2017 2
In last week’s blog, we took a Closer Look at 40 Gig Duplex Multimode
Applications, just one of the many ways that today’s data centers are cost-effectively
achieving increased bandwidth in switch-to-switch fiber links. And when we
say many ways, we literally mean many.
If you take a look at network application standards for balanced twisted-pair
cable, there’s not that many to be concerned with. Sure, we had a methodical shift from
10BASE-T, to 100BASE-T, to 1000BASE-T, to 10GBASE-T that then jumped back to
2.5GBASE-T and 5GBASE-T to accommodate new technologies over the installed base
and then forward again to the upcoming 25GBASE-T and 40GBASE-T standards, but all
of this is nothing compared to fiber. And unlike fiber, there are few, if any, non-standard
ways of deploying copper cabling.
But when it comes to fiber, there’s much that resembles the Wild Wild West.
While not necessarily characterized by the rowdy, unrestrained and disorderly behavior
associated with that era, there is certainly an untamed territory when it comes to fiber
deployments—many of which can be noted for lawlessness (or at least noncompliance).

For Ethernet application standards over fiber, it’s like a wide-open range where you can stake
your claim to achieve speeds from 1 to 100 Gig over a variety of multimode or singlemode options.
While 100 Mb/s over fiber had just one standard—100BASE-FX—that ran over what is now considered
legacy 62.5µm multimode fiber, 1 Gb/s fiber applications suddenly gave us six different options over
62.5µm or 50µm multimode or singlemode fiber at a variety of wavelengths and distances. And when
we moved to 10 Gb/s, we suddenly had 10 different standards to choose from.
During the initial development of 40 and 100 Gb/s fiber applications, the IEEE 802.3 Ethernet
working group was only looking at multimode fiber cable solutions. But that was short lived. If we now
look at the list of IEEE 802.3 standards, we see four different options for 40 Gb/s and six different
options for 100 Gb/s using multimode or singlemode fiber.
With the pending 50GBASE-SR standard – anticipated to release in 2018 – followed by
100GBASE-SR2 and short-reach singlemode fiber applications in development like 100, 200 and
400GBASE-DR4, this trend of multiple choices looks like it will continue. And if applications for OM5
WBMMF with WDM technology come to fruition, it won’t be long before there are six ways from
Sunday to achieve 100 Gb/s.

Over the past decade, large hyperscale and supercomputing data centers have needed to
achieve higher bandwidth speeds faster than IEEE could develop standards. That has led to a corral full
of nonstandard-based options, with many of the technologies driven by new industry consortiums and
alliances that have been working on next generation speeds outside of the existing IEEE 802.3
Ethernet working group.
As mentioned in our previous blog, we already have several non-standard bidirectional or
unidirectional 40 Gb/s duplex multimode applications using WDM technology. Currently there are
about a dozen non-standard ways to achieve 100 Gb/s. In fact, according to LightCounting market
reach, more than 60% of 40 Gb/ shipments and more than 35% of 100 Gb/s shipments are non-
standards based technologies.

Some of the technologies for high-speed fiber applications include variations of WDM and
new interfaces and form factors, such as the QSFP double-density (QSFP-DD) form factor being
developed to support 200 Gb/s and 400 Gb/s over eight parallel lanes. Also in development are
interchangeable and interoperable optical modules that can be mounted onto printed circuit boards.
These on-board optics being developed by the Consortium for On-Board Optics move optical
components from current pluggable modules directly onto line cards, which drastically increases
system density.
With hyperscale and supercomputing data centers deploying fiber technologies to meet their
own need for next generation speeds, it’s easy to see why fiber is a lot like the Wild Wild West. And
while some might consider them lawless outlaws, these pioneers are certainly helping to advance
technology that will someday benefit the rest of us.
