Cisco 1.2 GHZ Hybrid QAM Transmitter, ITU44 iWDM

Cisco's Prisma^® II optical networks support DOCSIS 3.1 features in growing fiber deep and remote PHY architectures. The Cisco Prisma II Hybrid QAM Transmitter (HQT) offers superior MER complete with 4k QAM and Orthogonal Frequency Division Multiplexing (OFDM) capabilities.

Designed to support the move to higher order modulation for capacity increases, the HQT also enhances legacy systems with analog capability combining the superior performance of externally modulated systems with the cost-effective and ease-of-use of familiar directly modulated transmitters. Low sensitivity to link-length variations make the HQT ideal for redundant rings. Adjustable dither control for varying Brillouin Scattering suppression (SBS) and iWDM wavelength plans ensure excellent performance when fiber non-linearities are unavoidable.

The first truly universal transmitter in the broadband marketplace, the HQT provides unprecedented value in the highly competitive service provider space. Flexibility to support traditional legacy and best-in-class architectures, the HQT is a transmitter that delivers performance with increased reliability, scalability, and cost-effectiveness.
