Ethernet on Fiber Optic Cable


Thread Starter

Atul Shah

I have a application for implimenting Ethernet Network for RTU's within a distance of 2KM. Total no. of RTU's within 2 KM end to end distance is 20nos.

The distance between RTU's range from 15 to 200 mtrs. The end to end distance of the fiber optic network will not exceed 2 KM.

The scheme I'm looking for is a ring network of Fiber Cable with nodes for RTU. This would be some what similar to RS485 network.

Things I request for the above are:
1. Is this kind of network feasible?
2. Who will be able to give me Electrical Cable to Fiber Optic convertor modules?

Thanks in advance.

Hirschmann has a very nice component called the RailSwitch RS1 or RS2. You can create a fibre optic ethernet 'ring' 10 Mbit or 100 Mbit. Each RailSwitch has 5 or 8 UTP connections.
