Hi Ajay,
You have asked about one of most latest technologies.
I think you have been talking about Optical MIMO and its implementation in optisystem
An optical multiple-input multiple-output (MIMO) communication system uses multiple LED-based transmitters and multiple receivers to transfer parallel streams of data. As compared to a single-transmitter single-receiver system using the same amount of signal power, a MIMO system can provide higher data rates with fewer transmission errors and better reliability.
I want to discuss advantage of coherent optocal MIMO (COMIMO) system as:
Advantages of COMIMO
Optical MIMO is based on the analogy between multipath
fading in wireless channels and modal dispersion in MMF and allows transmission of multiple data channels simultaneously
through a single fiber. Furthermore, selective modal launching requires
a time-invariant channel, for which one must also have an
accurate channel model a priori. Another distinguishing feature
is that MIMO signal processing requires detection of both
amplitude and phase information, in contrast to pure intensity
detection used in conventional fiber-optic links. The tremendous advantages afforded by COMIMO for MMF
communication are possible through advanced DSP. The use
of DSP to enhance the performance of communication links
is well established.
Thanks,
