Full duplex mode with just one fiber: new fiber-optic media converters with WDM technology
Two optical fibers are normally required for data transfer from serial interfaces, fieldbus systems or Ethernet via fiber optics. Devices with fiber-optic interfaces therefore offer duplex connections for a transmission line with two fibers.
This is made possible thanks to WDM technology. WDM stands for Wavelength Division Multiplex. This multiplex process uses both the 1310 nm and 1550 nm wavelengths. This enables you to transmit and receive simultaneously (bidirectionally) with a single mode fiber - and without restricting the transmission quality and bandwidth.
This means that the bandwidth can actually be doubled in existing fiber-optic networks by implementing two WDM media converter pairs.
Cost savings through the use of optical rotary transformers
The new WDM media converters enable wear-free optical rotary transformers to be used for just one fiber. Thanks to their simple design, they are significantly less expensive to purchase than rotary transformers for several fibers.
