data transmissoin system design

Oct 21, 2004 0 Replies

Hello, I am in need of some comm system advice......



I need to design a data communications system and I have limited previous knowledge and no previous experience so please HELP.



I have a 6 to 10km single mode fibre link between a camera module and a control consul. It needs 600+ Mbps upload (in small bursts) and general control signals download to the camera.



Since we need some transfer protocol to ensure reliable data transfer (and are on a limited budget) I though that 1Gb Ethernet cards would be suitable. What sort of percentage increase in data volume will the Ethernet packets create?



What are your thoughts, and do I have any other options regarding protocols ???????



Another problem is that we will be using other peoples fibre links. I have been assured that they are all good quality single mode fibres?? But we will not be guaranteed use of two fibres to allow duplex communication.



Does anyone know of a suitable dual wavelength (bidirectional) transceiver Ethernet card??



One alternative I was considering was some sort of forward error correction to allow simplex transfer of the uploaded data, but I think this will be much more complicated to implement than the Ethernet solution (and it needs a separate copper camera control line).



Thanks gc
