Telecast Fiber Systems offers powerful fiber transport system

The Python II 3G is Telecast Fiber Systems’ latest release of the company's Python multichannel fiber-optic HD-SDI transport system. The new Python II 3G offers the industry's broadest range of digital transmission rates while maintaining signal quality and reliability.

The Python II 3G enables fiber-optic transport of up to four groups of HD-SDI channels in a compact 1RU frame. For example, operators can select a transmitter and a receiver frame for eight or 16 channels in one direction or two transceiver frames for channels in each direction. Alternatively, they can use Telecast's Rattler miniature transmit/receive modules in conjunction with Python II 3G frames to distribute signals to and from several locations simultaneously. Because most Telecast SD/HD products can interface with the Python II 3G, broadcasters can create the exact topology required for a given operation.

In addition, the Python II 3G's coarse wavelength-division multiplexing (CWDM) capabilities enable it to transport up to 16 HD signals on a single optical fiber while remaining compatible with earlier versions of the Python. The system accepts signals ranging from 19.4Mb/s ATSC to 3Gb/s uncompressed HD-SDI and supports numerous interface standards, including applicable SMPTE, ATSC and DVB recommendations.

The FAA’s current rules and proposed ban on flight over people, requirement of visual line of sight and restriction on nighttime flying, effectively prohibit broadcasters from using UAS for newsgathering. ~ WMUR-TV General Manager Jeff Bartlett
