Coax vs. Twisted Pair

Smaller. Lighter. Simpler. Cheaper. These attributes of CAT 5-type UTP cable, in relation to coaxial cable, are well known. The small, lightweight cable fits into smaller conduit than larger, stiffer coaxial cable and is easier to pull, lowering overall project costs and allowing it to be used in applications where space is an issue. Terminations are simpler and less expensive with CAT 5-type cable than with coaxial cable.

With the price of copper increasing dramatically over the past few years, low-cost twisted pair cable has made a difference in keeping many projects within budget. Especially when cable runs exceed 200 feet or more, the cost of twisted pair equipment and inexpensive CAT 5-type cable can be significantly less than an equivalent run of coaxial cable, for which an interface or peaking amplifier might also be required.

Extron engineers have developed a broad product line that capitalizes on the benefits offered by the physical characteristics of CAT 5-type cable. Through superior quality, advanced technology, and award-winning design, we offer system designers and integrators even more reasons to consider using twisted pair for AV applications.

Let's explore some of those reasons:

Comprehensive Product Selection

Our broad range of options provides AV designers the ability to "right size" the twisted pair products at all points in the signal path. In this regard, we offer the most comprehensive twisted pair product selection in the industry.

MTP 1500RL 15HD RS SEQ
New MTP 1500 RL receivers for 1,500' distribution of high resolution video along with audio or RS-232.

Our MTP Series alone includes hundreds of transmitters, receivers, switchers, matrix switchers, distribution amplifiers, cables, and accessories. For example, with the Extron MTP Series, a system designer can select the right low resolution or high resolution transmitter or receiver for a given signal type and place a skew equalizer only where needed.

Figure 1 represents a point-to-point system using Extron MTP Series transmitters and receivers. The simple system depicted is transmitting one computer video signal, one S-video signal, and one composite video signal.

each point in the signal path.

With our products, a designer has much broader freedom to specify precisely the right transmitter and receiver for each signal type. Because our low resolution transmitters and receivers have a lower price point, the cost savings, compared to using a competitor's products, is dramatic.

Extron twisted pair products feature professional grade connectors and proper connectivity for the application, eliminating the need for additional cable adapters and increasing the savings.

Imagine the magnitude of the savings Extron's comprehensive selection of products would provide in a larger, more complex twisted pair application.

Integration-Friendly Features

In addition to providing dramatic savings over both coaxial cable-based systems and the twisted pair offerings of our competitors, MTP Series twisted pair products are designed to help solve common AV integration challenges. Extron engineers carefully consider how the design of each product will help integrators and installers with the efficient use of costly rack space, effective cable management, fast access to controls and adjustments, and ease of mounting. All rack-mountable transmitters, receivers, switchers, matrix switchers, distribution amplifiers, and accessories in the MTP Series feature connectors that are all on the back panel. This eliminates the need to run cables over or under the rack shelf and through the rack, saving valuable rack space and making it easier to manage the cables. See Figure 2.

Front panel adjustments make it easy to dial in image quality from one location, without having to repeatedly move from the front of the rack to the back during set up. This can save a considerable amount of time and frustration, especially in applications where space near the rack is limited.

Extron twisted pair products are designed in a wide range of form factors to provide integrators and installers with flexibility and freedom when it comes to deciding where and how to mount them. Rack-mountable products are housed in metal enclosures that are rack, under-desk, and projector pole-mountable using any of dozens of specialized Extron mounting products.

Many transmitter models are also available in wall-mount versions, as well as Extron's popular AAP and MAAP configurations. Some receiver models are small enough to mount behind a flat-panel display. Extron has the product and mounting solutions to help meet the architectural requirements of most any application.

MTP U Series Universal Receivers

Extron MTP U Series Universal Mini Twisted Pair Receivers accept a wide variety of video formats along with RS-232 or audio signals on a single UTP cable, providing dramatic cost savings with superior performance. With advanced features, including the ability to automatically route the incoming UTP signal to the appropriate video, audio, and RS-232 output connector, systems require only one receiver and one cable for each display.

MTPX Plus Series Matrix Switchers

For complex matrix switching applications, the MTPX Plus Series Twisted Pair Matrix Switchers are available in six I/O sizes from 8x16 to 32x32. Each model is compatible with Extron MTP Series transmitters and receivers. They are capable of routing video signals, along with audio or RS-232 control signals, on a single twisted pair cable. MTPX Plus Series matrix switchers offer an innovative feature set not available on any others.

Local video and audio inputs and outputs enable direct connection of equipment located within the same rack as the MTPX Plus Matrix Switcher, greatly simplifying system complexity by eliminating additional MTP transmitters and receivers.

Rack Efficiency

The equipment room provided just enough space for two equipment racks, one of which was devoted to Extron equipment including the Matrix 6400, DVS 304 scalers, and 46 MTP 15HD RS transmitters and receivers. Because the latter require their own external power sources, this could have posed a real challenge in terms of dealing with a clutter of wires and external power supplies, and also coming up with 46 available AC receptacles. Therefore, MIG-AVC decided to install six PS 123 Multiple Output Power Supplies, each of which could power up to eight twisted pair transmitters or receivers via short, custom-cut wiring. In doing so, the number of required AC outputs was reduced substantially from 46 to just six, and rack space was conserved since no trays were necessary for external power supplies.

"By using the PS 123 units, we were able to neatly organize the power cabling to the MTP units and achieve a very neat, clean installation," explains Mendoza. "This really helped us in managing power as well as eliminating a potential cluster of power supplies."

Extron from End-to-End

The use of Extron products and technologies enabled complete integration, from sources in the control booth, to the equipment room for routing and distributing video signals, and finally to the 40 flat-panel displays and projectors in the bowling area, bars, restaurants, pool tables, and other areas. This included various Extron cables for short-length video connections within the control booth and equipment room, as well as the twisted pair cable infrastructure to cover the expansive area of this facility.

Mendoza had specified Extron equipment for this and several other installations based on personal experience with Extron products and service over the past 15 years. "We've always been appreciative of Extron's customer service, which is second to none," he says. "And we've always known about the quality of their products, so selecting them for this project was an obvious decision for us, knowing that Extron would always be 100% behind us whenever we needed them."

MTPX Plus 1616
MTPX Plus Series Twisted Pair Matrix Switchers are available in six I/O sizes from 8x16 to 32x32.

MTPX Plus Series matrix switchers also feature dynamic skew equalization on all inputs and outputs. This industry-first innovation ensures that CAT 5-type cable skew is eliminated—no matter which combination of input/output cable lengths are selected.

Yet another innovative feature, local RS-232 insertion ports, allows a control system located near the MTPX Plus to connect to and control remote displays over the same CAT 5-type output cable that carries the AV signal. Additional features include switchable pre-peaking on a number of the outputs to drive signals long distances, audio input gain and attenuation to balance audio levels, output volume control for the local outputs, and IP Link® Ethernet connectivity.

These powerful features found in MTPX Plus Series Switchers enable integrators to greatly reduce installation time and costs associated with rack space, cabling, and installation, when compared to traditional twisted pair matrix switching.

More Reasons to Consider Twisted Pair

Twisted pair systems eliminate the need for separate cables for audio and control signals, since those signals can be carried together with the video on a single cable.

It is worth noting that twisted pair AV systems require a dedicated cable infrastructure that is completely separate from that used for data networking or voice applications. Although twisted pair AV and data network systems may seem interchangeable by virtue of a common type of cabling, they must be considered separate, distinct, and incompatible. AV signals are not formatted as packetized digital data for transmission over Ethernet, and therefore cannot coexist with data network signals within the same CAT 5-type cabling.

Conclusion

The bottom line is that twisted pair AV systems offer cost-effective, long-distance transmission capability with performance and picture quality similar to coax systems.

Although CAT 5-type cable was designed for data networking, it is also a viable, cost-effective alternative to running analog video and audio signals over conventional coaxial cabling. There are plenty of reasons to consider using twisted pair for your next application and even more reasons to choose Extron twisted pair solutions.
