The 5 most damaging structured cabling scenarios.


why such problems need to be addressed sooner rather than later? The following Cause-and-Effect checklist of the 5 most damaging structured cabling scenarios give a short explanations to illustrate them.

1.  Cause:  Intermittent faults – Unidentified intermittent faults are amongst the most common and damaging issues that affect structured cabling networks. Faulty patch leads and broken or malfunctioning outlets are typical causes of this frustrating and puzzling problem, but identifying the lead or outlet that’s misfiring can be a headache in itself.

Effect:  Valuable resources are wasted.

2. Cause: Wi-Fi problems – Wi-Fi can present a host of challenges when installed incorrectly – from poor coverage to intermittent connectivity. Connecting multiple devices that use conflicting Wi-Fi standards is a common cause of many problems. Equally, the Wi-Fi devices themselves may be faulty or installed in the wrong position. If neither of these factors are the cause of your issues, check if you’ve connected new Wi-Fi devices with outdated cabling.

Effect:  Workforce efficiency and productivity plummet.

3. Cause: Disorganization and disorder – Structured cabling networks often become disorderly over time as multiple firms are called in to install cable, maintain and repair them, resulting in a confused and jumbled system. A disorganized structured cabling network can also be the result of sloppy workmanship, where engineers haven’t taken enough care during the implementation process. Untidy patching, inaccurate labelling and poor record keeping are all warning signs that shouldn’t be ignored.

Effect:  Unnecessary expenditure.

4. Cause: Mismatched cabling –  Even if your infrastructure is built on one category of cable, if two different manufacturers have supplied different elements of your network, you may encounter problems. A structured cabling network that isn’t consistent end-to-end can cause electrical mismatching between components and although this can be difficult to spot, the effects are plain to see.

Effect:  Costly network challenges.

5.  Cause: A lack of network redundancy – Organizations need a backup cabling network and an uninterruptable power supply (UPS) to ensure connectivity and power remain consistent when the lights go out unexpectedly. This is especially true of critical links and services that underpin crucial business operations, for example the structured cabling network that supports a bank’s trading floor. Despite the importance of these systems, we find that many organizations don’t consider installing them until after an incident has taken place.

Effect: A catastrophic loss of service.

What’s Fibre Optic Cables

Fibre optic “cable” refers to the complete assembly of fibres, strength members and jacket. Fibre optic cables come in lots of different types, depending on the number of fibres and how and where it will be installed. Choose cable carefully as the choice will affect how easy it is for fiber optic installation, fiber optic splicing or  fiber termination and, most important, what it will cost!

Cable’s job is to protect the fibres from the hazards encountered in an installation. Will the cables be exposed to chemicals or have to withstand a wide temperature range? What about being gnawed on by a rodent or some animal? Inside buildings, cables don’t have to be so strong to protect the fibres, but they have to meet all fire code provisions. Outside the building, it depends on whether the cable is buried directly, pulled in conduit, strung aerially or whatever.

Since the plan will call for a certain number of fibres, consider adding spare fibres to the cable – fibres are cheap! That way, you won’t be in trouble if you break a fibre or two when splicing, breaking-out or terminating fibres. And request the end user consider their future expansion needs. Most users install lots more fibres than needed, especially adding singlemode fibre to multimode fibre cables for campus or backbone applications.

Why do we need to cleave optical fibers?

Optical fiber needs to be cleaved for fusion splicing. Optical fiber fusion splicing nearly always requires that the fiber tips exhibit a smooth end face that is perpendicular to the fiber axis.

This sufficiently perpendicular and planar fiber end face can be achieved via the fiber cleaving process. In this cleaving process, the brittle glass fiber is fractured in a controlled manner.

Polishing a fiber tip can result in even higher quality fiber end faces, but polishing requires more expensive equipment and more processing time, so it is very rarely employed for fusion splicing.

FS-C20 Fiber CleaverA fiber optic cleaver is a piece of tool or equipment to make an almost perfect fiber end face cut. Just like using a diamond scribe tool when cutting glass, a fiber cleaver’s cutting wheel (blade) makes a very tiny cut on the fiber first, then the fiber is pressed against the little cut to force it to break at 90° angle and expose a mirror like fiber end face.

The SYOPTEK FS-C20 Fiber Cleaver is designed to precisely cleave all 125um multimode or singlemode optical fibers. The high precise adjustable blade can perform up to 60,000 cleaves with a typical cleave angle of 90 degree.

Ocean Networks secures funding for Pacific submarine cable

Ocean Networks, Inc., a company planning to build a new submarine cable system in the South American Pacific Ocean, says it has secured mezzanine funding to start the project. The company declined to say who provided the funding.

The planned 9400-km system, named South America Pacific Link (SAPL), will be a new build submarine cable system that will connect Manta, Ecuador to Oahu, Hawaii. Ocean Networks says the SAPL system will fill a requirement for the emerging markets of South America and provide connectivity to the Asia Pacific region, Australia, and New Zealand, fiber optic cleaning  via interconnects with existing and planned submarine networks.

Hawaii is a mid-Pacific hub for numerous undersea cable systems. SAPL will provide a cost-effective, one click cleaner, direct low-latency route to Hawaii, opening up a previously untapped trans-Pacific market to/from the west coast of South America, the company says.

In addition, the SAPL system will land at Manta, Ecuador, where it can interconnect with planned and existing systems to provide a more direct, low-latency trans-Pacific route to the Caribbean region and U.S. East Coast.

Why do we need fiber optic cleaning?

Fiber optic cabling has become telecommunication backbone of today’s university campuses and enterprises. With the prosperity of Gigabit Ethernet and 10 Gigabit Ethernet, ensuring clean fiber optic connections has become one of the most critical requirements for maintaining error-free communication in these fiber optic communication systems.

Repeated fiber optic connector disconnection and reconnection often leaves debris in the bulkhead adapter or receptacle. With single mode fiber core as small as 9 micrometer, even a single 1 micrometer dust particle can cause a big signal loss or even interrupt the communication, if left blocking the fiber core.

Here are some samples pictures showing optical connector contaminations.

The Wavelengths Used In Fiber Optics

Fiber optics is full of jargon but it’s important to understand it. One of the more confusing terms to many is “wavelength.” It sounds very scientific, but it is simply the term used to define what we think of as the color of light.
Light is part of the “electromagnetic spectrum” that also includes x-rays, ultraviolet radiation, microwaves, fiber optic cleaning, radio, TV, cell phones, and all the other wireless signals. They are simply electromagnetic radiation of different wavelengths. We refer to the range of wavelengths of electromagnetic radiation as a spectrum.
Wavelength and frequency are related, so some radiation is identified by its wavelength while others are referred to by their frequency. For the radiation of shorter wavelengths, one click cleaner, light, UV and x-rays, for example, we generally refer to their wavelength to identify them, while the longer wavelengths like radio, TV and microwaves, we refer to by their frequency. wavelength

Data center and enterprise SDN market to exceed 3 billion by 2017

“The important question that everyone wants answered is, ‘What’s the real market for SDN?’,” says Cliff Grossner, Ph.D., directing analyst for data center and cloud at Infonetics Research. And the market research firm has attempted to answer that question. In its newly released Data Center and Enterprise SDN Hardware and Software report, Infonetics says the data center and enterprise software-defined networking (SDN) market will be worth over $3 billion by 2017.

While the Open Networking Foundation (ONF) has begun to consider how to apply SDN to carrier transport networks (see “Open Networking Foundation plans its 2013”) and several systems houses have launched their own efforts, the Infonetics report covers SDN controllers and Ethernet switches in use for SDN – what the research firm calls “the ‘real’ market for SDN” – separately from SDN-capable Ethernet switches.

“It’s still early days, but our research over the last two years confirms that SDN controllers and Ethernet switches in use for SDN will play a role in enterprise and data center networks, growing to a $3.1 billion market by 2017,” says Grossner. “Wide scale in-use SDN deployments will occur first in the data center with large enterprises and cloud service providers, followed closely by the enterprise LAN. We’re already seeing significant use cases for SDN in the enterprise LAN providing security and unification of wired and wireless networks, and enabling BYOD (bring your own device).”

Infonetics points out that the market is still young and that the majority of enterprises are still “kicking the tires” on SDN. Nevertheless, the space has seen early deployments for the large data centers of cloud service providers and large enterprises such as Google, NTT, AT&T, Verizon, DT, BT, and China Mobile.

Meanwhile, vendors have already begun shipping SDN products. This year has seen offerings from such companies as Alcatel-Lucent, Big Switch, Brocade, Cisco, Cumulus, Dell, Extreme, HP, Huawei, IBM, Juniper, Midokura, NEC, Pica8, Plexxi, Plumgrid, VMware, and others, Infonetics points out.

Looking forward, Infonetics expects 10% of Ethernet switches will be in use for SDN by 2017. North America, where SDN got its start, will see nearly 50% of the SDN revenue market share in 2017 as well, according to the report.

Report: Security systems integration market could exceed $30B

IMS Research forecasts that the Americas market for security systems integration will exceed $30 billion in 2016, and will grow at an average rate of more than 7 percent from 2011 until then. The firm’s new report, which focuses on the installation and maintenance of security systems in the Americas region, finds that the U.S. is forecast to remain the largest market in the Americas throughout this time. However, faster growth is forecast for Latin America countries such as Brazil.

“The Latin America market is a really exciting place right now for systems integration,” comments Paul Bremner, IMS Research market analyst and the report’s author. “A lot of technology providers are trying to establish themselves in this marketplace, including the large international systems integrators. In the U.S., it’s a different picture entirely, and I believe we’re seeing the start of consolidation.”

The Americas security systems integration market remains highly competitive, notes the research, with the largest five integrators accounting for less than 20 percent of the market. The market is seen as even more fragmented in some Latin American countries. Further, competition appears to be increasing, with traditional IT integrators entering the security market and taking market share away from the established security systems integrators.

IMS’s Bremner continues, “The security systems integration competitive environment is really interesting because the range of companies in the market is huge. At one end there are the enterprise integrators, like Johnson Controls and Siemens. At the other end, are five-man companies serving a product or geographic market niche.”
