Combo Device Servers

Moxa’s integrated serial device server solutions consolidate a wealth of features into an all-in-one design that combines a managed Ethernet switch and a device server into a single device. This design can satisfy multiple project requirements in a fraction of the space needed for separate devices, and both simplifies device configuration and reduces operational and maintenance costs.

NPort S8455I-SS-SC
NPort S8000 Series

4 RS-232/422/485 ports, 3 10/100BaseT(X) ports, 2 100M single-mode fiber ports with SC connector, 15 KV ESD, 12 to 48 VDC, 0 to 60°C operating temperature

      Fiber Cable Type OM1 50/125 µm G.652
      800 MHz x km
      Typical Distance 4 km 5 km 40 km
      Wavelength Typical (nm) 1300 1310
      TX Range (nm) 1260 to 1360 1280 to 1340
      RX Range (nm) 1100 to 1600 1100 to 1600
      Optical Power TX Range (dBm) -10 to -20 0 to -5
      RX Range (dBm) -3 to -32 -3 to -34

      Dispersion Penalty (dB) 3 1
      Note: When connecting a single-mode fiber transceiver, we recommend using an attenuator to prevent damage caused by excessive optical power.
      Note: Compute the “typical distance” of a specific fiber transceiver as follows: Link budget (dB) > dispersion penalty (dB) + total link loss (dB).
