REM, Quad Destacker

ATX’s return path stacker/destacker technology works in pairs between node/hub site and headend to greatly increase upstream bandwidth per wavelength. It “stacks” up to 4 independent RF returns, transmits over a single upstream laser and then receives in the headend to “destack” back to 4 independent RF outputs. This is similar to digital return in nature, but is more cost-effective, and higher return bandwidths are achievable. This destacker module complements both the I-HUB and TranScend stacker modules. ATX’s stacking return path solution provides unparalleled performance, flexibility and scalability for various network architectures. It is the preferred solution for increasing return network capacity for HFC and RFoG applications.

A new generation at work.

The I-HUB platform is ideal for minimizing fiber for Node+0, hub eliminations, node segmentations and RFoG, or reclaiming existing fibers for additional broadband subscriber narrowcast services and revenue generating business services. Learn more about this product.>
