Because the effect of dispersion increases with the length of the fiber, a fiber transmission system is often characterized by its bandwidth–distance product, usually expressed in units of MHz·km. This value is a product of bandwidth and distance because there is a trade-off between the bandwidth of the signal and the distance over which it can be carried. For example, a common multi-mode fiber with bandwidth–distance product of 500 MHz·km could carry a 500 MHz signal for 1 km or a 1000 MHz signal for 0.5 km.
Engineers are always looking at current limitations in order to improve fiber-optic communication, and several of these restrictions are currently being researched.
Each fiber can carry many independent channels, each using a different wavelength of light (wavelength-division multiplexing). The net data rate (data rate without overhead bytes) per fiber is the per-channel data rate reduced by the FEC overhead, multiplied by the number of channels (usually up to eighty in commercial dense WDM systems as of 2008).
Standard fibre cables
The following summarizes the current state-of-the-art research using standard telecoms-grade single-mode, single-solid-core fibre cables.
The 2018 NICT result is notable for breaking the record for throughput using a single core cable, that is, not using spatial multiplexing.
Research from DTU, Fujikura & NTT is notable in that the team were able to reduce the power consumption of the optics to around 5% compared with more mainstream techniques, which could lead to a new generation of very power efficient optic components.
