TeleThon 3G
Multichannel Wavelength Manager and 3G/HD/SD-SDI Transport
Lightweight, easy-to-deploy fiber connectivity solutions.
TeleThon 3G from Grass Valley, a Belden Brand, is
the single optical and electrical multiplexer that simplifies all your cabling needs. It accepts electrical
digital signals (via BNC), ranging from 19.4 Mb/s up
to 3 Gb/s uncompressed 3G-SDI and optical signals
of up to 3 Gb/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. The coarse wavelength division multiplexing (CWDM) capability of
the TeleThon 3G system simplifies and multiplies the
effectiveness of fiber optic cables, reducing operator costs and improving overall signal transmission
capacity.
Huge savings
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 48 Gb/s of
data, fewer fibers are used, resulting in less expensive cable and connector costs, and lower overall life
cycle costs for broadcasters.
Simplify complex configurations
Since the TeleThon 3G 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 your system. This
represents a huge savings not only in the costs of the
spares but in the overall complexity of managing the
individual wavelengths.
When you add the power and convenience of the
TelePort 3G to the high density signal transport of
the Python 3G, you end up with an ideal solution
for handling your ever changing production requirements. Whether you need it in the studio or out on
your mobile unit, the TeleThon 3G will fit seamlessly
into your existing fiber inventory and dramatically
increase your signal transport capabilities.
TeleThon 3G system is a compact 1 RU unit ideal
for HD studio infrastructures, sports and field production, HDTV distribution on corporate and educational campus, and other facilities requiring reliable,
efficient delivery of HD and other signals.
New life to old gear
The true value of the TeleThon 3G system comes from
its ability to accept an optical signal and re-transmit it
on a CWDM wavelength. By doing this, your optical
signal is being amplified and repeated. The TeleThon
3G gives you a fresh optical budget and extends the
usable life of older single wavelength fiber products.
Now all of your existing fiber products are CWDM
ready.
