Clark Wire & Cable Outfits Fiserv Forum in Milwaukee With Fiber, Connectivity


BMO Harris Bradley Center has housed the Milwaukee Bucks, Marquette University Golden Eagle’s and decades of concerts for 30 years. Now, they are ready to let go of this building full of memories, so a new building can move in downtown, Fiserv Forum.

Construction began back in June 2016, where Mortenson Construction, ICON Venue Group, and Parsons Electric came together to build the $524 million project. The venue has a 17,500 seat capacity and it measures 714,000 square feet. Along with the arena, the building will take up 4th St. and Juneau Ave. with an entertainment plaza. The center is designed to share the history and the personality of Milwaukee. The first event the building hosted was on September 4, 2018 with “The Killers” and “The Violent Femmes” along with four other events to follow this month. Throughout the building, cabling from Clark was used.

‘We used all Clark products for the broadcast video cabling, audio cabling, and interface panels,’ says Parsons Electric Senior Project Manager Erik Carlson.


Specifically, Clark provided the interlocking armored optical fiber cables, the hybrid SMPTE camera cables, triax camera cables, multi and single pair audio cables, HD/SDI coaxial cables, network cables, photo-strobe cables, speaker cables, and custom panels for this project.

Carlson also shared that Clark Wire and Cable handled other crucial aspects of the project brilliantly.

“getting material to the site as needed and [helped with] the individual break up of that was required whether it was cable lengths or pre-packaging of the panel, so that when we got to site [we had] what we needed and when we needed it”


The service and quality of product is what drew Carlson to Clark product and ultimately helped him decide to use them for this project.


In October, the Milwaukee Bucks officially move in to take on the first games of their pre-season.



The Importance of Cleaning Your Fiber-Optic Cable Assemblies


The ability to transmit enormous amounts of data over long distances in an instant is a distinct advantage of fiber optic cables. Fiber installers, however, must ensure that contamination on the fiber connectors is minimized in order to stay within the acceptable range of data loss. Oil and dust particles small enough to be invisible to the naked eye are large enough to block the entire 9µ core diameter of a single mode fiber. Smaller soils increase signal attenuation and return loss and have the potential to cause permanent damage to the connectors.

Most contaminants are impossible to see without the aid of a microscope as the fiber core is several times smaller than a human hair. Furthermore, the act of mating and de-mating connectors causes dust particles outside of critical areas to accumulate and redistribute onto the connector end face. Additionally, mating a dirty plug cross contaminates the other plug.
Now that we know the importance of keeping your SMPTE cable assemblies clean, we can move to the next step; testing your SMPTE assemblies.

The Clark CWT-SMPTE is the only SMPTE cable tester of its kind. A two-piece test set designed specifically for testing both the fiber and copper elements of a terminated SMPTE 304/311 camera cable assembly. The fiber elements are tested for power loss and displayed in dB loss, while the copper elements are tested for multiple combinations of opens and shorts. What’s more, measurements are displayed on color touch screen display for easy viewing and operation.

  • Clean all the fiber contacts on both the tester and cable to be
    tested prior to connection.

  • Dirt, dust, and debris can not only create additional loss, they can also permanently damage the ceramic contacts. Failure to properly clean the fiber optic contacts prior to testing can result in damage to the tester and void the warranty.

    Clark recommends contacts can be cleaned with the Clark FOC-CK-OCS, one-click cleaning pen for 2.0mm SMPTE fiber optic contacts.


  • Periodically check the fiber contacts for contamination and damage. Clean the contacts as described above. With the power off on both units (for eye and sensor safety), inspect the contacts with a microscope such as the Clark FOT-SCP3-F2.

  • NOTE: If deep scratches or cracks are found on the contacts, contact Clark to have the unit repaired.



Considerations for Power Distribution in Racks



The role of rack systems in A/V system integration includes more than housing equipment. Providing sufficient power, proper grounding and adequate ventilation can all play a vital role in the functionality of a rack system.
Whenever we work with AC power safety must ALWAYS be the first consideration.


Solid wiring practices must be strictly followed as it is sometimes easy to overlook the deadly potential of AC power, especially when the system operator is under the gun and troubleshooting the system becomes neccessary.
When distributing power in a rack is neccessary (not all systems call for it) there are a number of things to consider.

  • Does the system allow for safe and easy plugging and unplugging of equipment?

  • Are components easliy installable and flexible?

  • Is it easy for electricians to ‘hook-up’ to?

  • Are the quantity of individual AC and technical-ground circuits adequate?

  • Is there enough room for expansion if needed?



A couple of the more popular power distribution systems include plug-strips, power-bars (commercial grade),
and duct-powerbars, used in larger, fully-engineered systems.

Although some of the questions presented may seem obvious, just being aware of them may cause great headaches later.

Why you Should Reconsider Your Category6 Network Cable


Ethernet is the most commonly used computer networking technology for local area networks (LANs) and is ETL verified to TIA-568-C.2 and ISO/IEC 11801.

As technology advances Ethernet continues to find its way into other applications. In fact, it is becoming the cable of choice for high-level industrial applications and harsh environment landscapes.

In order for Ethernet to be used in the industrial environment,
the cables and connectors must be adapted to withstand
environmental conditions that are not present in commercial
installations. These conditions include:

  • Oil

  • Chemical

  • Sunlight

  • Abrasion prone

  • Flexing


In addition to harsh environmental conditions, environmental noise can have a negative affect on network performance.
Electrical noise from nearby AC or DC circuits, electrical motors, and other electrical equipment
may result in increased RFI and EMI interference, which can decrease system performance.

Industrial network connectivity needs be able to withstand all of these conditions and still reliably perform. More and more industrial applications require clean data, which increasingly makes Ethernet the optimal solution for today’s
industrial environments.

Luckily Clark Wire and Cable offers a ruggedized Cat6 snake cable designed for staging and remote production applications.


The CNS4C6S features an abrasion resistant and extra-flexible outer TPE jacket with each Cat6 element shielded with a 100% foil/Mylar tape.
What’s more, the CNS4C6S includes four network elements within a single cable!

Three Most Important Aspects of Digital Cable


One of the most common questions we come across is: what attributes make a good digital cable? Since a digital signal operates in a wide frequency band, it only makes sense to have a video cable that can support this. With so many important questions to consider when deciding to purchase products for digital video, we thought it would be helpful to shed some lights on product attributes that make up a good digital video cable.

1. Solid Copper Center Conductor – If you are dealing with signals above 50 MHz, a center conductor made of copper clad steel (CCS) is acceptable. This is because at frequencies above 50 MHz the signal will migrate to the outer portion of the center conductor. At higher frequencies there is no need for a solid copper center conductor, so a CCS cable is appropriate. The problem is that since a good portion of a digital signal extends below 50 MHz, a cable with a 100% copper center conductor should be used.

2. Effective Broadband Shielding – When it comes to cable shielding, more of the same isn’t necessarily better. Often times customers are, understandably, under the impression that a cable with two braid shields is always the best option. Although braid shields offer up to 95% coverage, this is only the case at higher frequencies. You can achieve maximum protection at all frequencies by using a cable that offers a 95% braid shield plus a foil shield (100%).

3. Gas Foam Injected Dielectric – There are many choices of dielectric material for coaxial cable but in the digital realm we should chose a dielectric material that offers a good high frequency response, is fairly flexible yet relatively firm to prevent center conductor migration. Gas foam injected dielectrics have a good frequency response and is the best option for a digital cable.

We hope this sheds some light on properties that you should look for when considering digital cable. Until next time, Happy Wiring!

Justification for Using 13g 4c Cable in Place of 10g 2c Cable



There are two important factors to consider for this article:

High-powered loudspeakers and their associated amplification (usually over 1,000 watts) produce high current demands and often 10-gauge wire is preferred to reduce voltage drop.

The current-carrying capability of a conductor is determined by its cross-sectional area.



Cross-sectional area is determined in a round conductor with the formula:



1
2
3
4
5
6

11
A(Square Inches) = πr
2 where π is the constant 3.14159.
10-gage wire has a conductor diameter of 0.1019 inches.
13-gage wire has a conductor diameter of 0.0720 inches.

Using the radius formula, where “r” is the radius and “d” is the diameter:

r = d/2, r = d/2

The radius of a 10-gage wire is: r = d/2 = 0.1019/2 = 0.0510, and
The radius of a 13-gage wire is: r = d/2 = 0.0720/2 = 0.360.




Now that the radius is known, the cross-sectional area can be calculated with the
following formula:



1
2
3
4
5
6

A = πr^2

Thus,
The area of a 10-gage wire is: A = πr^2
= π(0.0510)^2
= π(0.0026) = 0.0082.
The area of a 13-gage wire is: A = πr^2
= π(0.0360)^2
= π(0.0013) = 0.0041




Adding two 13-gage wires together produces a cross-sectional area of
0.0041 + 0.0041 = 0.0082, the exact cross-sectional area of a 10-gage wire.
Thus, by pairing two sets of two 13-gage conductors together, Clark SPKR1304 cable can be used as a direct substitute for SPKR1002 or any other 10-2 cable.

Doesn't Your $500,000 AV Project Deserve a Solid Team?


In all areas of business, understanding of how teams function, having efficient and effective team processes as well as a solid understanding of what these processes are can lead to effectively meeting project goals.

Sure, individuals make high quality decisions every day in business but the truth of the matter is,the tasks related to these individual decisions are relatively simple1. The more complex the tasks,the greater the need for a team. With the potential of hundreds of thousands of dollars at stake in AV system projects, isn’t it worth it to consider building a solid project management team?

Having a solid team allows the team leader to draw from a diverse area of experts, it opens up alternative suggestions that may not have been thought of before and allows for a systematic process of achieving specific goals. It should be noted, however, that just because a ‘team’ is assembled doesn’t necessarily guarantee effective results. Often the result of ‘throwing together’ a team is the much maligned management by committee.

In order to gain a broader perspective of team processes we can consider four main aspects2 that have a considerable effect on team effectiveness.

1. Have a Rigorous Decision-Making Process - At the heart of any team is a solid decision making process. Without a systematic way of arriving at the best possible solution, the success of a team is dubious at best. Having a solid decision-making process also helps to avoid certain pitfalls that may side track a team. One common pitfall is the solution trap. It is human nature to want to provide an immediate solution to the problem at hand. Often times the first solution seems so reasonable that it gains favor with group members but this only exacerbates the situation and may lead to the team not considering better alternatives.

There are many wonderful decision making models that can cure the solution trap and they all minimally rely on problem identification, generating solutions (as in more than one), refining solutions and implementing solutions. One of my favorites is the PrOACT Approach as detailed in Smart Choices: A Practical Guide to Making Better Decisions.3

2. Observe and Analyze Participation - Who participates in the group? To what extent do they participate? Is it the same people every time? The goal here is to level the playing field of team member participation. This is easier said than done as cultural and gender differences can affect participation.4 How do we level the playing field? The first step is to observe your team and understanding how individuals in the group contribute. For example, one person may be assertive and direct while another reserved but detailed. The next step is to determine how wide the participation gaps are. There will always be some level of disparity but glaring discrepancies should tell you that you have some work to do. Finally, if needed, we can narrow the gaps by implementing a number of strategies. For example, the team leader may act as a mediator, so-to-speak, in order to make sure that all points of view are taken into account. Another idea is to provide a framework, such as Six Thinking Hats, that relies on input from a number of perspectives. If you have a pessimist on your team, great! give ‘em the black hat of looking at a solution cautiously and defensively.

3. Influence - Participation relates to the level at which team members offer input, and influence describes the ability of team members to capture and engage fellow team members. While influence certainly is welcome we must not allow it to circumvent the process. In other words, consider the ‘influencer’s’ opinion but don’t allow it to exclude other opinions. One way to avoid over-influencing is to purposely comment on opinions that are being overlooked. This not only sends a message to the group that there is an even playing field but also allows all alternatives to be considered. As world chess champion Emanuel Lasker once said “when you see a good move, look for a better one.”

4. Conflict Management - “A good manager doesn’t try to eliminate conflict; he tries to keep it from wasting the energies of his people…” - Robert Townsend.
In order to build a cohesive team we must learn how to manage conflict. There are a number of excellent conflict management models available but you should choose one that leads to productive conflict 5. For more information see previous blog on Conflict Management Models
The goal of any project is to arrive at the best possible outcomes for a wide variety of decisions that have to be made. Considering these four concepts as it pertains to your team should provide the framework needed to reach these solutions
