Free Space Optics is the technology which implies the line-of-sight link for the transfer of data between two distant points. The beam of light is used to provide optical connection that can transmit ...

The move is underway to coherent optical fiber for long-haul dense wavelength division multiplexing (DWDM). Here's what you need to know to test and optimize these optical networks. Fig 1. In this ...

In this paper, performance analysis for different combining technique for receiver diversity in a MIMO system is presented. A general framework for diversity combining techniques in cooperative ...

New optical chips deliver 28 Gb/s of data using DP-QPSK to meet the accelerating demand for more and faster Internet data. Fig 1. A DP-QPSK transmitter and a coherent receiver with ADC and DSP are key ...
