Lightron Fiber-Optic Devices, Inc. 10-Gbps HSFP with Wavelength Stack-up Technology

    March 11, 2016
    The 10-Gbps HSFP product line provides eight wavelengths within one 13-nm CWDM spectrum. Short CWDM wavelengths beyond the dispersion penalty are available in 10-Gbps CPRI/OBSAI and Ethernet as well.

    The 10-Gbps HSFP product line provides eight wavelengths within one 13-nm CWDM spectrum. Short CWDM wavelengths beyond the dispersion penalty are available in 10-Gbps CPRI/OBSAI and Ethernet as well. HSFP (High-Density SFP) is an advanced CWDM bi-directional pluggable optics approach that enables users to experience a 2X or 6X increase in fiber line operation efficiencies, thanks to its wavelength stack-up technology.

    Lightron says its wavelength stack-up technology provides two, six, or maximum eight adjacent wavelengths within a 13 nm tolerance. In conjunction with its thermo-electrical cooling design from the company's Cooled BOSA (bi-directional optical sub-assembly), the technology enables CWDM links with 36, 108, or more wavelengths operating over the industrial temperature range. And its design reduces the effects of Rayleigh backscattering and back reflection.

    Use of the technology also does not require the introduction of new passive modules into the network, the company adds.

    HSFP transceivers have already been deployed to support LTE roll outs in Korea. Enhanced versions that will support greater reach will widen the application space within wireless applications and 10 Gigabit Ethernet networks.Judge's comment: "Just making a WDM SFP is not innovative, but this SFP solves an industry problem, and has lots of innnovation such as bi-di that works, multiple channels squeezed into existing bands, and compatibility with already fielded channel plans."
