High Rate Optical Transmission Parts

To get the most out of existing and new optical transmission systems, novel techniques are required to maximise data rates, channel density and minimise the effects of fibre link limitations. BBN International announces a range of advanced high performance components and modules to enable high capacity optical transmission, 40Gbps and above, to be achieved over standard fibre links. These products are designed to compensate for the limiting factors of fibre Optical Interleavers are used to double DWDM channel densities by combining separate odd and even channels with 200, 100, 50GHz spacings. D(Q)PSK Demodulators achieve high data rates over longer reach links and the latest modulation schemes such as the highly spectrally efficient PM-(D)(Q)PSK enable even faster rates over longer reaches. 90° Optical Hybrids for coherent signal demodulation provide both amplitude and relative phase information so that optical transmission impairments can be compensated in the electrical domain.
