Fiber Optic Multiplexers
Featured Product from Moog Inc.
To exploit the full bandwidth of fiber, multiplexing combines many signals of various types - video, serial data, network data, control lines - onto one optical fiber. Multiplexers that combine a number of signals electrically are typically called time division multiplexers (TDM); discrete parts of each input signal is assigned a time slot in the outgoing data stream. Moog has a wide range of TDM options that allow multiple electrical channels to be multiplexed onto one or more optical fibers.
We also produce multiplexers that combine a number of optical signals onto one or two fibers. These multiplexers use wave division multiplexers (WDM) because they transmit different signals on different wavelengths of light on the same optical fiber.
Both multiplexing techniques can be used separately or together to simplify optical transmission systems and reduce cost, improve reliability, reduce weight and improve performance. Multiplexed systems also simplify system upgrades since numbers of channels and channel bandwidth is a function of the electronics rather than the transmission line or components. Moog multiplexers accommodate the ever-increasing data rates needed for digital video and industrial data protocols, as well as high speed networks such as Ethernet and IEEE-1394 (Firewire).
