With each fiber strand capable of moving up to 48Gbps of data, fewer fibers are used, resulting in less expensive cable and connector costs and lower overall lifecycle costs for broadcasters

Telecast Fiber Systems, the industry’s most experienced company in video over fiber signal transmission, introduced the Telethon™ 3G multichannel wavelength manager and HD/SDI transport system at the NAB 2011 Show. The new Telethon now handles 3G signals with no increase in price while remaining backward compatible with earlier 1.5G versions of the Telethon.

Through its coarse wavelength division multiplexing (CWDM) capabilities, the Telethon 3G simplifies and multiplies the effectiveness of fiber optic cables — reducing operator costs and improving overall signal transmission capacity for a wide range of studio and outside broadcasting environments. All of the transmitters and receivers are now reclocked using Telecast's vast experience in signal transmission, insuring that no other fiber optic transport system is more stable.

“The Telethon 3G is our latest tool to reduce the cost and complexity of moving large numbers of wideband signals through fixed or mobile infrastructures. With each fiber strand capable of moving up to 48Gbps of data, fewer fibers are used, resulting in less expensive cable and connector costs and lower overall lifecycle costs for broadcasters,” said Steve DeFrancesco, vice president and general manager at Telecast Fiber Systems. “At a compact 1RU, the Telethon 3G is ideal for HD studio operations, sports and field productions, HDTV distribution on corporate and educational campuses, and other facilities requiring reliable, efficient delivery of HD and other signals.”

The new Telethon 3G optical and electrical multiplexer system is a hybrid device that combines the CWDM wavelength management functionality of the company's Teleport™ 3G system with the dense digital signal capacity of the Python™ 3G digital video transceiver system. The Telethon unit accepts electrical digital signals ranging from 19.4Mb/s to 3Gb/s uncompressed HD/SDI and optical signals of up to 3Gb/s each, and multiplexes them for transmission in either or both directions. Up to 16 optical signals can be accommodated on one fiber, significantly increasing fiber capacity.

Since the Telethon accepts the optical output of virtually any digital transmitter and turns it into a specific CWDM wavelength, there is no need for “wavelength-specific” devices in the system. This represents a huge savings not only in the cost of spares but in the overall complexity of managing the individual wavelengths. In addition, because Telethon can accept any optical signal and retransmit it on a CWDM wavelength, the optical signal is both amplified and repeated — extending the usable life of older fiber optic systems.
