“GigaBOB” (Remotely Powered Balun)
HZ 5002-1 (Free Hanging)
HZ 5002-2 (Free Hanging with Diplexer)
HZ 5004-4 (Wall Mount with Diplexer)
The Z-Band Video Distribution System enables the long awaited convergence of Voice, Data and Video over the same cabling plant.
Simplifies Design, Installation, Adds/Moves/Changes of the Video Distribution infrastructure while electronically insuring High Quality Pictures to all TV’s. Z-Band enables the integration of
RF and IP Video. IP Video can be an evolutionary transition, not a revolutionary change with the Z-Band Video Distribution System.
The “GigaBOB”/balun is one of the basic components of Z-Band’s high definition Video Distribution System. It is located at the receive end of the system and permits a TV, Set-Top Box/Cable Box or PC with a Tuner Card to be connected to the system for HDTV over CAT 5e, 6 or better cable. The balun is not only an impedance matching device, but serves also as a small self-adjusting amplifier and signal conditioner that senses its distance from the hub and adjusts its output to assure proper signal level to the TV at distances of 10-100 meters. The input to the “GigaBOB” from a wall outlet is connected via a RF-45 Jack for IP applications.
Available in free-hanging and wall mount configurations with a uni-directional capability for RF video only , or a bi-directional capability for video, data and VOD applications
Which Balun is Right for You?
Standard Balun (HZ 5002-1)
The Z-Band Standard Balun is a one-way device that matches the impedance of the incoming Category/twisted pair cable with the out-going coax (to the TV). This means the RF energy/signal only travels down- stream to the TV and does not allow any signal to travel back upstream from the TV or Set-Top Box. (The Standard Balun doesn’t have the extra components required for return RF signals).
Therefore, the Standard Balun is the best choice (lowest cost) if there isn’t a requirement for a Set-Top Box or video-on-demand device.
When the standard Balun is used, it determines the distance from the Video Distribution Hub to the TV and adjusts the TV signals (both gain and slope) to help compensate for the loss in the twisted pair cable. This is a patented feature of the Z-Band Balun. The power necessary for this feature (gain/slope) is provided by the Video Distribution Hub located in the telecommunication closet. This eliminates the need for any external power source (such as a power cube) at the TV.
The Z-Band Diplexer Balun is a two-way device that not only matches the impedance of the different cables, but includes a diplexer in a“specialized filter circuit.” This circuit passes broadcast RF signals to the TV but it also filters the low frequency signals which are used to send information back from the TV/Set-Top Box. This information is necessary to maintain contact with the service provider, and also instructs the service providers’ electronics to respond to the user’s video-on-demand request.
Without a Diplexer Balun the information coming back from the TV would be blocked by any amplifiers in the system, and the users Set-Top Box would not function properly. And in some cases, even the regular RF programming would never reach the TV. When using the Diplexer Balun there is another very important feature; the frequency used by the CATV service provider for the return information turns out to be highly susceptible to outside inference which can affect this return information.
However, the Diplexer Balun automatically closes this pathway, thereby, eliminating any return noise, and only opens this pathway for milliseconds to allow the Set-Top Box to send its requested information. This feature results in a relatively noiseless system that is less compromising than a shielded coax system.
