Huawei SSN1D75S (D75S) 32xE1/T1 75-ohm electrical interface switching board for OptiX OSN1500B/2500/3500/7500.

The Huawei SSN1D75S (D75S) is a 32xE1/T1 electrical interface switching board (75-ohm) for the Huawei OptiX OSN platform, used on OSN1500B, OSN2500, OSN3500 and OSN7500 when working together with a PQ1 PDH processing board. The D75S receives and transmits 32 E1/T1 electrical signals at 75-ohm impedance, acting as a PDH interface switching outboard that provides signal input and output for the associated processing board. Huawei also offers a 120-ohm equivalent (D12S) for networks using that impedance standard; the D75S is the correct fit for 75-ohm E1 environments common in European PDH networks. Tech-Star (UK-based, shipped worldwide) stocks tested Huawei optical transmission hardware; enquire for stock and compatibility.
