Transportation-Intersection-Expressway Connectivity Quick Reference Guide

This Quick Reference Guide lists EtherWAN’s best-selling network connectivity products for Intelligent Transport Systems (ITS). Through a few simple steps, you’ll be able to select the right EtherWAN product according to your requirements. If you need further assistance, please don’t hesitate to contact our sales department.

Information needed to select the proper Power over Ethernet (PoE) or non-PoE Switch:

  1. How many cameras are you connecting?
  2. Are the devices 10/100 Fast Ethernet (FE) or 10/100/1000 Gigabit Ethernet?
  3. Will you need room for additional cameras (expansion) in the future?
    1. It is always a good practice to have some extra PoE ports available for future expansion.
  4. Do you require Fiber Optic connectivity?
    1. If so, what type of fiber optics will be used? Single Mode (SM), Multi Mode (MM), or Wavelength-division Multiplexing (WDM)?
    2. What speed (FE/GE) and distance? What type of connectors (SC, ST, LX, LC, SFP, etc..) are needed?
      1. 100M Fiber
        SFP mode for variable distance
        2Km Multi mode (MM)
        10Km Single mode (SM)
        20Km Single mode (SM)
      2. 100M Fiber
        SFP mode for variable distance
        550m Multi mode (SX)
        10Km Single mode (LX)
        20Km Single mode (LX)
  5. Are you connecting a network uplink to a central office and downlink to next switch?
    1. If yes, you need two extra ports for network uplink & downlink. Calculate total bandwidth for all devices in order to choose uplink & downlink ports bandwidth.
  6. Does your network application require redundancy?
    1. If, yes, choose a managed switch that supports the EtherWAN Alpha-Ring protocol, RSTP, or STP.
  7. Are you connecting devices that require active PoE (802.3af or 802.3at), such as Wireless AP (WAP), IP cameras, digital displays or VoIP phones?
    1. If yes, what is the maximum power draw (wattage) of each PoE device? Refer to the datasheet for the camera or the manufacturer’s website.
    2. If the wattage of all devices is below 15.4W, then an IEEE802.3af PoE switch should be sufficient.
    3. If the wattage of any connected device is greater than 15.4W, then choose an IEEE802.3at PoE switch.
    4. If the wattage of any device is greater than 30W, then consider purchasing an ultra-PoE switch.
    5. Add up total wattage from all cameras. This figure will be used to determine the required PoE power budget.
  8. Make sure you select a switch that has a large enough PoE Power Budget to cover the total power draw calculated in #7-e above. It is a good practice to allow for 20% overage on the power budget.
    1. Example: Each camera draws 12 Watts x 8 cameras = 96W. After adding a 20% margin, a 115.2W minimum PoE budget is recommended.
  9. Managed vs. Unmanaged switch? We always recommend at least Web-Smart management, as this allows for troubleshooting as well as remote power cycling of individual devices. A managed switch is also required if VLAN, QoS, Redundancy, or Security is required.
  10. Installation Location:
    1. Outdoor Deployment : Operating Temperature -40 ~ 75°C (-40 ~ 167°F).
    2. Indoor deployment with air conditioning: Operating Temperature 0 ~ 45°C (0 ~ 113°F).
    3. Indoor Deployment without air conditioning: Operating Temperature -10 ~ 60°C (14 ~ 140°F).
  11. Consider purchasing a surge protector if the Ethernet cables will be run outside of a building.
