Abstract: The transmission of a data signal (DS) in the form of data packets takes place by means of angular modulation, preferably two or three stage difference phase modulation. The header (HEAD) is transmitted by means of polarization modulation. An additional channel formed in this way is also available for the transmission of additional information. To separate the header (HEAD), the multiplex signal (DHS) is aligned in a specific polarization level, so that the header can be separated without any problem. A new header can be added without having to convert the data signal into an electrical signal beforehand.

Abstract translation: 数据分组形式的数据信号（DS）的发送是通过角度调制进行的，最好是两级或三级差分相位调制。 标题（HEAD）通过偏振调制传输。 以这种方式形成的附加通道也可用于传输附加信息。 为了分离报头（HEAD），多路复用信号（DHS）在特定偏振电平中对齐，使得报头可以分离而没有任何问题。 可以添加新的标题，而不必事先将数据信号转换成电信号。

Abstract: Systems and methods for reducing modal group delay when transmitting a plurality of optical signals over a transmission line that supports a plurality of modes are disclosed. The modes are converted at a plurality of positions along the transmission line so the signals in the end have minimal group delay. The method comprises the steps of receiving N number of optical signals into a multimode fiber having at least N modes, transmitting each of N signals into a mode of the at least N modes of the multimode fiber, and converting each of the N modes into another of the N modes at N positions along the transmission line, such that the net modal group delay generated between the N signals along the transmission line is minimized.

Abstract: The invention describes method and an arrangement for transmitting an orthogonal frequency diversity multiplex signal via an optical filter. OFDM channels located near an edge of an OFDM spectrum are copied and shifted to an opposite edge of the OFDM spectrum and transmitted via the optical filter. At the receiver symbols are derived from original and the copied OFDM channels. Then the symbols having a better signal quality are elected for further processing.
