The Oclaro micro-iTLA features high optical output power and off-grid tuning suitable for applications in 100G and next generation 200G coherent networks based on the PM-QPSK and 16-QAM modulation formats.
The SetPal technology provides for a DVB (digital video broadcasting) compliant digital terrestrial receiver that supports COFDM transmission and QPSK (quadrature phase shift keying), 16-QAM (quadrature amplitude modulation), and 64-QAM.
The capabilities of the CDM-600, which is fully compliant with all Intelsat Open Network specifications and provides data transmission up to 20 Mbits/second, have been greatly enhanced with the addition of 16-QAM modulation employing both TPC and Viterbi/Reed-Solomon FEC.
The Southern Photonics IQScope-RT is a proprietary coherent optical receiver that accepts a single optical input and demodulates a DP-QPSK or 16-QAM signal into two I-Q electrical signal output pairs with bandwidth up to 45 GHz.
Users can select from QPSK, 16-QAM and 64-QAM modulation; and can select TDMA and FDMA technologies, all of which can be supported simultaneously within a sector, thereby providing superior design flexibility to network engineers.
