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.

Optical Losses

Optical loss or attenuation can vary from 300 to 0.2 dBm/km for plastic or single-mode fibers, respectively. Optical fiber has different loss characteristics at different wavelengths. The optical windows, as mentioned earlier, are regions within the optical fiber spectrum with low loss.

The earliest fiber-optic systems operated in the first optical window in the 850 nm range. The second window is the 1310 nm range, which has zero dispersion. The third window is the 1550 nm window. A multimode fiber has an attenuation of about 4 dB/km at 850nm and about 2.5 dB/km at 1310 nm. The multimode fiber spectrum attenuation curve is shown in Figure 6.10-3. Note the high loss regions at 700, 1250, and 1380 nm. The single-mode fiber attenuation curve is shown in Figure 6.10-11. There are high-loss regions at 800, 1100, and 1490 nm regions. The high-loss region at about 1100 nm is called the mode transition region. This is where the fiber changes from multimode to singlemode characteristics.

In order to make use of the low-loss properties of a given region in the fiber, the optic light source must generate light at that wavelength. For multimode fiber, light sources are used in the 850 and 1310 nm wavelengths. In single-mode fiber, light sources are typically at 1310 and 1550 nm. CWDM lasers are in the 1470–1610 nm range. The curve in Figure 6.10-11 shows that the fiber has low loss and a flat spectrum at these wavelengths. Corning introduced a CWDM metro fiber that eliminated the high water peak or the high-loss region centered at about 1380 nm. Most single-mode fibers, on new installation, use this flatspectrum fiber with a usable spectrum from about 1270–1610 nm. The new fiber gives the ability to have up to 18 CWDM wavelengths on one single-mode fiber.

Most video fiber-optic systems take advantage of the 18 usable wavelengths. CWDM is far less expensive than its 42 wavelength counterpart, DWDM. With the fiber-optic systems available with up to 8 channels of video per wavelength, when combined with the capabilities of CWDM optical multiplexing, more than 144 channels of video can be transported over one fiber.

Plastic fiber is used over short distances due to high attenuation. The visible light region at around 650 nm is used over plastic fiber. Optical attenuation is constant at all bit rates and modulation frequencies. The attenuation in copper cable increases at higher bit rates and modulation frequencies. In a copper cable, a 100 MHz signal will be attenuated more per foot than a 50 MHz signal. This results in distances and bandwidth limitation. In a fiber cable, the 100 Mhz and 50 MHz signals are attenuated the same.

The Future of Video Fiber Optic Transport

Systems are currently in development for the transport of high resolution video at bit rates exceeding 10 Gbps.  Digital cinema and the proliferation of high definition television will demand fiber optic transport systems with high bandwidth capabilities.  Fiber transport to the home of video, telephone and internet traffic is slowly becoming a reality in many North American communities.  This will fuel the demand for high speed content delivery and distribution throughout the globe.

Bandwidth

The optical losses and usable bandwidth of a fiberoptic system have to be taken into account. As mentioned
previously, multimode fibers have greater losses and less bandwidth compared to single mode.
Single mode has lower losses and very high bandwidth than does multimode.

Most manufacturers of multimode fiber-optic cable do not specify dispersion. They will provide a figure
of merit known as the bandwidth-length product or just bandwidth with units of MHz-kilometer. For
example, 500 MHz-km translates to a 500 MHz signal that can be transported 1 km. The product of the
required bandwidth and transmission distance cannot exceed 500:

BW × L ≤ 500

A lower bandwidth signal can be sent a longer distance.
A 100 MHz signal can be sent

L = BW – product/BW
= 500 MHz-km/100 MHz
= 5 km

Single-mode fiber typically has a dispersion specification provided by the manufacturer. The dispersion
is specified in picoseconds per kilometer per nanometer of light source spectral width or ps/km/nm. This
loosely translates to the wider the spectral bandwidth of the laser light source, the more dispersion. The analysis of dispersion of a single-mode fiber is very complex. An approximate calculation can be made with
the following formula:

BW = 0.187/(disp × SW × L),

where:

disp is the dispersion of the fiber at the operating wavelength with units seconds per nanometer per
kilometer.

SW is the spectral width (rms) of the light source in
nanometers.

L is the length of fiber cable in kilometers.

For example, with a dispersion equal to 4 ps/nm/km, spectral width of 3 nm, and a transmission length
of 20 km, then:

BW = 0.187/(4 × 10–12 s/nm/km) × (3 nm) × (20 km)
BW = 779,166,667 Hz or about 800 MHz.

If the spectral width of the laser light source is doubled to 6 nm the bandwidth will drop to about 390
MHz. This shows how significant the spectral width of the laser source is on the usable bandwidth of a fiber.
If a laser light source with a narrow optical spectral width is used, or a fiber with a lower dispersion figure,
the bandwidth and transmission distance will increase.

In single-mode fiber communications, there are two basic types of laser light sources. The first type is the
less expensive laser that uses Fabre-Perot laser diode (FP-LD) technology. The FP-LD is an inexpensive
choice for digital fiber-optic communication. With a spectral width of typically 4 nm or more, it is primarily
used for lower bandwidth or short-distance applications. The second is the distributed feedback
laser diode (DFB-LD) technology. These light sources are more expensive and are widely used for longdistance fiber-optic communications. The typical spectral width for a DFB laser is about 1 nm. When a DBF laser is used in combination with a low dispersion fiber, the transmission bandwidth and distance can be significantly higher.

See Table 6.10-2, which shows the typical fiber-optic cable losses, and Table 6.10-4, which shows the bandwidth for different types of fiber cable.

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.

Photonic Fiber Optic Switcher

The first is 100% optical switching using 3D MEMMS Technology.  It uses electronically controlled mirrors to route optical signals.  This type of switch has an Optical input, an Optical cross-point and an Optical output.  The abbreviation for this technology is OOO.  An OOO switch provides only Point to Point switching.  One input can not be multicast to many outputs.  The mirrors can not point to more than one output at a time.  The use of mirrors does permit multiple wavelengths in both directions.  Switches are available is sizes from 8 by 8 to 256 by 256.  Pure optical switching is available for Multimode and Singlemode applications.  Optical switching supports both analog and digital optical signals.

Pure optical switching is performed using 3D micro-electro-mechanical mirror (MEMS) arrays.  Tiny mirrors are fabricated out of silicon.  The mirrors are positioned and controlled with electrostic charges.  The core of the optical switch is a one inch square cube.  The cube has an array of up to 256 input fibers on the left side as shown in figure 33.  Each fiber has a lens that focuses the optical light onto a MEMS mirror.  Each input has its own mirror.  On the right side is an array of output fibers.  Each output has a MEMS mirror.  An optical connection is made when one input mirror aligns with one of the output mirrors.

Fiber Optic Switching is ideal for video broadcast, production, security and other video applications requiring transmission, switching and replication of high quality optical signals.  The Fiber Optical Switcher revolutionizes how video is distributed and managed. It is based on sate-of-the-art field proven photonic switching technology. Laser light is switched in a pure optical format, without electrical conversion, allowing it to support transparent connections compatible with any video or data format including uncompressed HD video at 1.5 Gbps.  Also, since the switching is done optically, the switch eliminates video degradation. With a traditional electrical switcher, Electrical to Optical (EO) and Optical to Electrical (OE) conversions are required which cause signal degradation and jitter.

An optical switch supports a wide range of formats from 19.4 Mbps ATSC through 3.0 Gbps HDTV as well as NTSC, PAL, SECAM, SMPTE 259M Serial Digital (SDI) Video, broadband analog, DVI, HDMI, RGB, VGA, component, L-Band, IF, and many more. The optical switcher will also transparently switches CWDM and DWDM signals.

Optical switcher technology can be used in the field to support applications requiring reliable, high-quality video distribution such as Mobile production trucks, sports venues and professional video facilities; Campus video and surveillance networks; Remote video monitoring as well as Government and military.  Optical layer protection and fault tolerant switching can be configured for mission critical, non-stop applications.

Optical switching is extremely cost effective for any applications requiring thirty-two or more switched optical ports. It eliminates the need for expensive video transceivers to convert signals between electrical and optical formats. Switching the signals in optical format can save thousands of dollars per port in fiber optic transport equipment costs.
