摘要： An optical data receiver comprises an optical input for receiving optical data signals, an optical sputter for splitting the optical signals into first and second receiver arms, an optical filter in the first receiver arm, means for increasing an intensity ratio of optical signal strength in the first receiver arm to optical signal strength in the second receiver arm, means for adjusting a phase difference between the first and second receiver arms, and an optical coupler for coupling outputs of the first and second receiver arms to a photodetector. The receiver of the present invention selectively filters a carrier component of received optical data signals, adjusts the relative strength of the carrier component and the received signal and then recombines them. In this way efficient optical transmission can be achieved with direct detection at the receiver, without the need for a complex receiver design including a local oscillator.

摘要： A device and method for depolarising the total field of a wavelength division multiplexed (WDM) signal is provided. A polarisation maintaining multiplexor combines a plurality of optical signals to form a polarised multiplexed signal. The multiplexed signal is then passed through a differential group delay (DGD) element adapted to modify the polarisation state of one or more optical source signals within the multiplexed signal and thereby to at least partially depolarise the multiplexed signal.

摘要： A feedforward controller for controlling the polarization state of an optical signal. The feedforward controller includes an optical input for receiving an optical input signal having an input polarization state, an optical output for transmitting an optical output signal having an output polarization state, a polarization controller coupled to the optical input and the optical output, and a transfer function determiner for determining a characteristic polarization transfer function of the feedforward controller from the input and output polarization states. The polarization controller is adapted to modify the polarization state of light passing therethrough in dependence on the characteristic polarization transfer function of the feedforward controller.

摘要： An optical signal scrambler (18) has an optical phase modulator (22) which has a common input/output for an optical signal. The modulator also has an input for a modulating signal and a common output/input which is coupled to a 45° Faraday mirror (24). The scrambler (18) operates to modify an optical input signal received at the input/output of the modulator (22) so that it is returned as an output which is phase scrambled.

摘要： An optical signal transmitter (10) is constituted by a coherent light generator (12) for generating a carrier wavelength and a modulator apparatus (16, 32) coupled with the output of the light generator. The modulator apparatus has a series arrangement of an optical intensity modulator (16) and an optical phase modulator (32) coupled between the input and an output of the modulator means. The intensity modulator (16) has an input (26) for a non return to zero (NRZ) digital signal of a predetermined data rate as defined by a clock generator. The phase modulator (32) has an input coupled with the clock generator which provides pulses to the phase modulator at the data rate, or at an even multiple of the data rate, but phase shifted relative to the data signal such that one end of each digital period is red shifted and the other end is blue shifted to facilitate detection.

摘要： An active branching unit for interconnecting three cables (two trunk cables and one spur cable) each including optical fibres. In a first interconnection configuration fibres of the trunk cables are connected together via the spur cable. Optical switch means, comprised for example by an erbium doped fibre amplifier (EDFA) (20) and an optical attenuator (21) in series, are disposed between optical fibres of the two trunk cables and are such as to pass telecommunications traffic between the trunk cables when, for example, there is fault in the spur cable and an alternative configuration is required. In this case a pump signal is applied to the EDFA (20) and the loss of the attenuator (21) overcome so that traffic can pass directly between the trunk cables and thus be diverted from the spur cable. This path switching can be achieved automatically.

摘要： A polarization mode dispersion compensator that includes two stages, one for reducing or eliminating first order polarization mode dispersion of an optical signal, and second stage for reducing or eliminating higher order polarization mode dispersion of the optical signal. In each stage, the polarization is adjusted so as to reduce polarization mode dispersion. Based on the power levels of various polarization states generated at the second polarization controller, the optical signal to noise ratio may be estimated. Furthermore, based on the amount of adjustment used to control the polarization controllers and the differential group delay, the polarization mode dispersion may be estimated.
