The Cisco Prisma II high-density long-reach multi-wave (HD-LRMW) transmitter is the monolithic hybrid optical source module. Based on quaternary indium phosphide semiconductors, it separates the functions of light generation from RF modulation. The result is a smaller size, lower cost, narrow linewidth component, providing performance, more often associated with discrete external modulator technologies. Longer distance transmission without the linearity degradation of directly modulated sources is possible, expanding the capabilities of dense wavelength division multiplexed (DWDM) optical links to facilitate architectures with unprecedented versatility and flexibility. Consistent with other Prisma II transmitters, the HD-LRMW offers RF spectrum and transports a multiplex of analog, quadrature amplitude modulation (QAM), and orthogonal frequency division multiplexed (OFDM) channels with unmatched performance for node segmentation, fiber reclamation and fiber deep architectures. The features, characteristics and value position this transmitter to address the broad range of applications in the fluid broadband access market.
