The TeleThon and the Telethon 3G (shown) are the single optical and electrical multiplexers that simplify all your cabling needs. They accept electrical digital signals (via BNC), ranging from 19.4 Mbps up to 1.5Gbps for the Standard telethon and 3Gbps for the Telethon 3G of uncompressed HD/SDI and optical signals, of similar bit rates, 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 CWDM (coarse wavelength division multiplexing) capability of the TeleThon systems simplify and multiply the effectiveness of fiber optic cables, reducing operator costs and improving overall signal transmission capacity.

Telecast's Teleport and Teleport 3G (shown) multiply the effectiveness of your fiber optic cables and solve your high bandwidth signal transport needs. The results are lower cable costs and simpler management of your broadcast facilities.
The TelePort accepts the optical output of virtually any digital transmitter, such as our Viper, Adder, Cobra, etc., and converts the signal into a specific CWDM wavelength. At the other end, A CWDM demultiplexer directs the signal to your standard receiver. There is no need to purchase customized wavelengths for each system, or to buy spares for each wavelength. The TelePort handles it all easily and seemlessly.
