Route66-OAR
Quick Start Guide 3 / 7 rev. 1.1
Connecting Route66-OAR
The Route66-OAR automatically creates cross-points between all router ports connected to active devices to form
a closed fiber optic ring network.
While using Route66-OAR it is important to properly setup the fiber ring protocol before connecting via Route66-
OAR. It is recommended to test the standalone system before plugging it to Route66-OAR.
Two corresponding LC router ports starting with the odd port number creates the connection SLOT for a single
device fiber optic links (Router port 1 & 2, Router port 3 & 4 ... Router port 39 & 40). It is recommended to connect
always port A of the external device to the odd Route66 port in the SLOT and port B to the even Route66 port of
the same SLOT (port naming might differ depending on the protocol, in some protocols, i.e. Optocore, keeping
this order is not required). Always both duplex fiber links from one device/location must be connected to two
neighbour router ports – to the same SLOT. Different connection than described above may lead to incorrect
Route66 patching which won’t allow closing the loop between all devices.
The router SLOTs do not need to be used consecutively, pair-wise router ports can be left blank, or the connected
devices can be switched off. Route66 automatically discovers which slots are occupied and patches them will all
other occupied SLOTs.
Route66-OAR advanced port routing algorithm discovers which SLOTs are occupied and routes from the first
active even port to the next active odd port. The last active even port is patched then to the first odd which closes
the loop. Example: if devices are connected to SLOT 1 (ports 1,2), SLOT 4 (ports 7,8) and SLOT 8 (ports 15,16)
Route66 will patch with the following order: 2 -> 7, 8 -> 15, 16 -> 1. All inactive ports are skipped. Once another
device is added in SLOT 3 (ports 5,6) the Route66-OAR will reroute to: 2 -> 5, 6 -> 7, 8 -> 15, 16 -> 1. Routing
action is very fast however it may affect network stability for a very short time – this depends on the fiber ring
protocol.
