Fiber Dispersion Will Change The Way You See Your Links

Optical data signals are comprised of very short bursts of light, or optical pulses. When we transmit optical pulses through fiber, they broaden. This means that they become longer in duration as they travel through the fiber. If the fiber is long enough, this broadening causes the pulses to overlap and interfere with each other, which impacts the receiver’s ability to resolve the transmitted data, resulting in bit errors. This pulse broadening is due to a phenomenon called dispersion and limits the transmission bandwidth and distance. Single-mode and multi-mode fiber are each dominated by different types of dispersion.

New design could make fiber communications more energy efficient

Researchers say a new discovery on a U.S. Army project for optoelectronic devices could help make optical fiber communications more energy efficient. A new design of optical devices radiate light in a single direction. This single-sided radiation channel for light can be used in a wide array of optoelectronic applications to reduce energy loss in optical fiber networks and data centers. The journal Nature published the findings. Light tends to flow in optical fibers along one direction, like water flows through a pipe. On-chip couplers are used to connect fibers to chips, where light signals are generated, amplified, or detected. While most light going through the coupler continues through to the fiber, some of the light travels in the opposite direction, leaking out. A large part of energy consumption in data traffic is due to this radiation loss.

Wavelength-Division Multiplexing (WDM)

WDM is an abbreviation for Wavelength-Division Multiplexing, and is now one of the most widely used technology for high-capacity optical communication systems. At the transmitter side, multiple optical transmitters – each emitting at a different wavelength – individually send signals and these signals are multiplexed by a wavelength multiplexer (MUX). The multiplexed signals are then transmitted over one main transmission line (optical fiber cable). At the receiver side, the signals are de-multiplexed by a wavelength de-multiplexer (DEMUX) and sent to multiple receivers.
