TeleThon 3G
Multichannel Wavelength Manager and 3G/HD/SD-SDI Transport

TeleThon 3G 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.
