Drop cable length can be adjusted in Network Architecture Manager. On the left hand pane select Hub-only Split -> Terminal Configuration -> Max Distance From Terminal (Meters).
Additionally, Distance Constraint Strategy field allows user to decide how strictly drop cable length setting is enforced. “Always Connect” allows locations that are too far from road edge to be connected, even if they are beyond maximum drop cable distance, while “Honor Distance” will drop the locations that fall outside of drop cable range.
From network design point of view, Arrow connects MDUs using dedicated network equipment (MDU equipment), and feeder cable running directly to the premise. SFUs, on the other hand, connect to the network via drop cable linked to a FDT, which is then connected to FDH using distribution fiber.
MDUs are automatically detected in Arrow by looking at number of households present on a given lat-long. This could be either a single location/data record with large number of households attribute assigned to it, or many records/locations of size 1 on the same lat-long.
Location size cutoff between SFUs (and connecting via FDTs) and MDUs (connecting via MDU equipment) is set in Network Architecture Manager. Select your plan type in the left hand pane (Direct Routing, Hub-only Split or Point-to-Point -> Fiber Capacity Configuration -> Consolidation Rules -> Multi Dwelling Unit Upgrade Threshold -> Threshold. The threshold value is the minimum number of locations to qualify as MDU.
In general, Arrow’s algorithms will consider conduit cost when determining optimal (cheapest) route to reach target locations, e.g. prefer cheaper aerial route vs. more expensive underground path.
It is possible, however, to set the tool to consider attributes of the conduit being used, and prefer running fiber through conduits with like attribute values (e.g. with sewers labeled ‘alpha’, ‘beta’, ‘gamma’, build a route that is predominantly ‘alpha’, minimizing the times fiber has to switch from one sub-type to another).
This Tollbooths functionality can be set up for projects working with data that contains the necessary attributes. Please contact Arrow support team to discuss further.
Please refer to Arrow User Guide’s pages dedicated to the resource manager for detailed explanation of each setting.
