There's also a lot of PR bullshit that gets repeated by the technology media and in explanations to non technical customers, such as showing somebody a multimode OM4 cable used for intra-building 100GbE with MPO/MTP connectors.
100GBase-SR4 optics are cheap (relatively) but require running a MPO/MTP OM4 cable from router-to-router or router-to-agg-switch. https://en.wikipedia.org/wiki/100_Gigabit_Ethernet#100G_Port_Types On Sat, Oct 15, 2016 at 11:10 AM, <[email protected]> wrote: > > How many different modes can you put on a fiber??? > Singlemode fiber supports, as it's name indicates, one fundamental mode, > which consists of two orthogonal polarization modes. > Multimode fibers support more than 100 modes. > > The problem is, we don't have the MIMO technology to deal with more than > a few modes, so can't just use multimode fiber with all it's modes. > Most research concentrates of so called few-mode fibers with a total of > six polarization and spatial modes. > > Jared >
