Telecast Fiber Systems today announced the launch of the TelePort(TM) 3G multichannel coarse wavelength division multiplexing (CWDM) management system. By taking advantage of CWDM's ability to multiply the effectiveness of fiber optic cables for high-bandwidth signal transport, the TelePort 3G is ideal for a variety of applications including outside broadcast, metropolitan video transport, studio-transmitter links, and inter-facility communications.
"CWDM has become the preferred approach to optical multiplexing in digital video/audio communications because of its reliability and cost advantages. Designing systems around CWDM, however, can be a complex task," said Steve DeFrancesco, vice president and general manager at Telecast Fiber Systems. "The TelePort 3G removes the complexities to make CWDM easy, flexible, and economical -- reducing cable costs and simplifying management of broadcast facilities."
The new TelePort 3G provides better performance and easy high-bandwidth multiplexing on just one single-mode fiber for as many as 16 digital fiber optic devices. The TelePort can accept the optical output of virtually any digital transmitter in the 1300-nm and 1550-nm wavelength windows, such as Telecast Fiber System's Viper(TM), Adder(TM), or Cobra(TM), and convert the signal into a specific CWDM wavelength. On the other end, a CWDM demultiplexer directs the signal to any standard receiver. With each port capable of 3Gbps transfer, double the rate of the original TelePort, one unit can support up to eight HD cameras, 2,048 AES channels, or any mix of signals required.
"With the TelePort, there is no need to purchase customized wavelengths for each system, or to buy spares for each wavelength. You can take the fiber optic systems you already own and combine them all on one or two low-cost fibers, and the TelePort handles it all easily and seamlessly," added DeFrancesco. "For a big event, a broadcaster can bring in more equipment and have it be instantly compatible. And, since the TelePort is repeating the optical signal, operators get a fresh optical budget and another 25 kilometers of distance -- or up to 50 km with the available APD option."
The TelePort 3G is among several new Telecast Fiber Systems innovations for fiber optic transport on display in the company's booth at the 2011 NAB Show, C8925.
