New Solution Offers Up to 80 HD Signals and Option for a Signal Generator and HD Monitors

LAS VEGAS, APRIL 6, 2010 – MultiDyne, a premier provider of fiber optic-based video and audio transport and routing solutions for broadcast and pro A/V applications, will unveil its brand new LiGHTCuBE fiber optic field transport system at this year’s NAB (Booth C7637). In addition, MultiDyne will also introduce the option for an HD or composite signal generator as well as HD monitors on the LiGHTCuBE, giving broadcasters unprecedented ability to test and monitor signals in the field.

Capable of housing any product in the MultiDyne product line, the LiGHTCuBE represents the company’s most customizable, rugged and high-density solution to date. Designed for the fiber optic field transport of composite, HD video, PL, IFB, audio and more, the LiGHTCuBE can be configured for as many as 80 HD-SDI, SDI or composite video paths, with 225 AES or analog audio channels. The LiGHTCuBE is also compatible with DVI, RGB and HDMI and is AC and fully battery powered.

In addition, the new test and monitor features make the LiGHTCuBE especially effective for in-the-field signal monitoring. With an HD monitor and signal generator on either end of the product, users can test the circuit even if the camera has not arrived. Further, the HD test signal generator option also allows users to send the test pattern down the line, or to send the signal from the studio end directly to the LiGHTCuBE. This function allows users to monitor the camera output and the signals arriving at the shoot, and can be added to any solution in MultiDyne’s LiGHTBoX product line.

“With our new LiGHTCuBE, the options for the end-user are virtually limitless,” says Frank Jachetta, senior vice president of sales and operations for MultiDyne. “Not only does the LiGHTCuBE hold more HD, analog video and audio signals than any other solution in our product line, it is also extremely customizable, even by the end-user. Our new test and monitor features provide even more value. Customers who were creating their own makeshift flyaway case to house many video signals will finally have access to a smaller, cost-effective and extremely high-quality solution for all their fiber optic transport needs.”

A major benefit also lies in the LiGHTCuBE’s size. Though this solution is heavy on HD and audio signals, the LiGHTCuBEv is a compact and extremely portable 14-inch cube design, making it small enough for sports and ENG, an announce booth setting, as well as any field application where signal density is a must. Additional carry handles allow users to “grab-and-go” for remote or on-location broadcasts. A weather resistant cover is also available.

The LiGHTCuBE is exceptionally versatile and can be used in a number of different broadcast and pro A/V situations. It is ideal for applications including large-scale outdoor arena sporting events where a user requires a rugged, highly weather-proof solution for handling massive amounts of HD signals. The LiGHTCuBE is also a perfect fit for users transporting high-density audio; for example, in a live symphony or orchestra broadcast setting with over 60 microphones, the LiGHTCuBE can manage audio bottlenecks, transporting signals seamlessly to an OB van or studio.

The LiGHTCuBE can be linked using tactical or conventional fiber to any MultiDyne solution, including the DVM-2500, HD-1500, HD-3000, HDMI-ONE, DVI-6000 as well as many non-MultiDyne products. In addition, the LiGHTCuBE offers users intercom, PL, IFB and belt pack support.  For more information on the LiGHTCuBE and its optional test and monitor features, please visit the MultiDyne website at: http://www.multidyne.com/productdetail.cfm?ProductID=247.

Electro-optical Switcher, OEO

The second type is the Electro-optical switch.  The Electro-optical switch uses a hybrid approach.  The input is Optical, the cross-point is Electrical and the output is Optical. The abbreviation for this technology is OEO.  An OEO switch supports point to multi-point or multicast switching.  Any input can be switched to every output if necessary.  Since the optical signal is converted to electrical, only one wavelength can be switched at a time.  Also an electrical cross-point only operates in one direction.  Therefore only one wavelength in one direction is supported.  MultiDyne provides a wide array of Electro-optical Fiber Routing Switchers scalable from 16 by 16 up to 288 by 288 matrix sizes.  Electro-optical routing switchers can switch any digital opticsl signal type from DVI Dual Link, Audio and Data to analog video and RGB-HV.  The EOS-4000 is the only large scale routing switcher that can support DVI Dual Link up to 2560 by 1600 or WQXGA.  When combined with the DVI-6000 DVI Dual Link and RGB-HV Fiber Optic Transport Systems, the EOS-4000 Series of Electro-Optical Fiber Routing Switchers will support all your DVI and RGB-HV signal distribution needs.

Optical Repeaters and Distribution Amplifiers

There are applications in fiber optic communications where a signal requires regeneration and replication.  The function required is similar to that of a distribution amplifier or digital signal relocked.  Passive splitter can be used to split an optical signal, but each signal is significantly weaker after the split.  A device call an optical repeater or distribution amplifier can be used to repeat or regenerate a weak optical signal.  This is helpful on long fiber optic runs where a fiber signal is reaching its limit.  The repeater can be used to regenerate the signal for further distribution.

The same device can be used to replicate an optical signal.  One optical signal can be replicated up to eight times with one device.  Unlike the passive split were the optical output is diminished, the output optical signals are regenerated to full optical power.

The device can also be used as a Mode Converter or Wavelength Re-mapper.  The device can be configured with a Singlemode input and Multimode outputs.  This give the ability to convert from Multimode to Singlemode or from one wavelength to another wavelength.  The device can convert an optical signals to CWDM wavelengths.

The ODA-8000/16000 Family of optical distribution amplifiers support virtually any digital fiber optic signal or format.  The system will support digital fiber optic systems that transport analog video, component video, DVI, HDMI, RGB — HV, VGA, SDI, HD — SDI, 3G HD — SDI and many more.

The figure 30 below shows applications for such a device.

Optical Multiplexing

We can take the multiplexing or combining of information one step further.  Optical multiplexing techniques can be used in addition to the TDM techniques mentioned above.  If both optical and TDM are combined, very large bandwidths of information can be transported by one fiber.

Wave-Division Multiplexing

Wave-division Multiplexing or WDM is the technique of taking two or more wavelengths or colors of light and combining them onto one fiber. On one end of the fiber the two wavelengths are combined and then on the other end separated.   Basic WDM uses two wavelengths.  In Multimode the 850 and 1310nm wavelgths are used.  In Singlemode, 1310 and 1550nm are used.  The two wavelengths can travel in the same direction or in opposite directions.

Fiber-optic connectors should be cleaned with lint-free optical wipes, and 100% pure isopropyl alcohol
should be used with the wipes. Compressed air is also useful to clean any dirt and debris from connectors or
receptacles. There are cassette-type cleaning devices that have an advanceable cleaning ribbon. The tips of
a male fiber-optic connector are typically ceramic. A protective cap should always be applied to the connector on the fiber cable as well as to the connector on the fiber equipment. This prevents damage and dirt
build up.

Optical Time Domain Reflectometer (OTDR)

More extensive test can be performed with an optical time domain reflectometer or OTDR. An OTDR is a sophisticated device that sends a calibrated light source at a specific wavelength down one end of a fiber.  The unit is very sensitive and measures the extremely low levels of light reflected back through the fiber.  It works very much like sonar.  In sonar an audio tone is bounced off objects.  The size of the reflection and the delay determine the size and distance of the objects.  As the down stream light beam from the OTDR hits connectors, splices and other defects in the fiber, it reflects small amounts of light back to the OTDR.  Based on the size of the reflection and the time it takes for the reflection to return to the OTDR, the system will provide a calibrated representation of the attenuation and flaws in an optical fiber. The OTDR analysis can be performed at different wavelengths with various modulation schemes.  An OTDR analysis is typically only necessary on very long fiber runs with many optical connectors, patch panels and splices.  It is easier to predict optical losses and bandwidth on the majority of fiber optic cable run since there will be a minimal number of connectors and splices.  Most applications will not require an OTDR.

Measuring Optical Power

The optical power output from a fiber optic transmitter or fiber cable can be measured with a simple and inexpensive light meter.  The light meter is calibrated for each of the three optical windows, 850, 1310 and 1550nm.  The meters are available with interchangeable connectors so that systems with any fiber connector type can be tested.   The meter gives a reading in milli-Watts or dBm (decibels per milli-Watt).  When trouble shooting a fiber optic system, the first step is to see if the transmitter unit is sending any optical power.  The technician will attach the meter to the transmitter with a fiber patch cord.  The output optical power of the transmitter can then be confirmed against the manufactures data sheet.  If the transmitter is within specification, the next step is to see if light is making it through the fiber to the receiver side.  If the light level output he transmitter does not meet specification, this indicates the source of a possible failure. If the transmitter output is within specifications,  reconnect the transmitter back to the fiber, connect the optical meter to the receiver side of the fiber.  Measure the light  from the end of the fiber.  Calculate the theoretical attenuation for the length and characteristic of the fiber in use and deduct it from the measured .   Using the theoretical attenuation of the fiber and subtracting it from the transmitter optical output power, the power level that should be present at the fiber end near the receiver can be calculated.  As long as the optical power level at the received is higher than the receiver optical sensitivity, the fiber link should operate.  If there is a low or no optical signal at the end of the fiber on the receiver side, the fiber may be damaged or have faulty or dirty connectors.  Lint-free optical wipes, Isopropyl alcohol and a can of compressed air can be used to clean all optical connectors.

A test of a fiber optic cable can be performed prior to the purchase of fiber equipment.  If a calibrated optical source is not available, handheld calibrated light sources are available as a companion device to the optical power meter.    The calibrated light source can be attached to one side of the fiber and the optical meter to the other end.
