posted:

10/09/2009

Belden, has introduced a high-quality SMPTE311 HD Camera Assembly that supports 720p, 1080i and 1080p. HD cameras provide digital transmission using SMPTE311 standard fiber optic cable for connecting to the camera control unit. In addition to their exceptional quality, HD cameras can transmit all digital bi-directional video and audio signals, one control line, power line, and prompter line over extremely long distances - up to 4000 meters with Belden SMPTE311 HD Camera Assemblies.

Belden already produces one of the best-known SMPTE311 cables in the world and the new Belden hybrid fiber SMPTE311 HD Camera Assembly was designed specifically for high definition (HD) fibered broadcast cameras. It is ideal for Studio and Field Camera Applications, requiring multiplex audio and video signals and power. Network TV studios, sports arenas, stadiums and production facilities are just some of the venues that will benefit from this new SMPTE311 HD Camera Assembly. Potential applications include interconnect of remote field cameras for Electronic News Gathering (ENG), and Electronic Field Production (EFP).

Next generation HD applications

The new Belden SMPTE311 HD Camera Assembly is the perfect choice for next generation HD applications and will replace SD infrastructure where stiff, heavy, triax cable is currently employed, or in long haul situations. The use of the global standard Belden SMPTE311 HD Camera Assembly significantly improves productivity, especially for rental companies, by eliminating the need for several different interface blocks and saving storage space, thus allowing substantial cost savings. Ideal for use in studios or in the field as well as for permanent installations, these assemblies are suitable for HD video installers; HD system integrators; HD OB van users; HD equipment rental companies; and camera teams in professional broadcasting, studios, sports stadiums, concert venues and live outdoor broadcasts. The global standard SMPTE311 HD Camera Assembly supports the SMPTE304 interface of all HD camera manufacturers. Today, no other medium can challenge fiber optics in bandwidth, distance and noise immunity. With fiber optics, the transmitted signals are not distorted by any form of outside electronic, magnetic or radio frequency interference. Therefore, optical cables are completely immune to EMI, RFI or high voltage interference.

Smaller and lighter

Compared to conventional triax cables of the same signal carrying capability, the smaller diameter and lighter weight of the hybrid fiber cables means easier installation, especially in crowded areas or limited space. In addition, a hybrid fiber cable is about half the weight of a comparable triax 14 cable. To improve upon the physical performance values at the connection point, there are several options to choose from. One of the best ways to provide ultimate connector performance is to terminate the fiber in the factory. Using proper termination of the cable eliminates potential water ingress and/or damage to fiber within the connector, and reduces problems in handling power, because the connector is prevented from being filled with water.
