[3dem] Falcon 3 question

[Fco Javier Chichon]

Dear all,
In our case we tried 2 configurations once we realized that is just 
simply not possible to have the storage close to the microscope without 
cabinet, the configuration FEI give to us.
Then e decided to move it to the CPD of the center, very convenient. For 
that we install 2 fiber optic cables form the wall close to the CMTS 
module (the one that send the movies directly from the FALCON to the 
storage) to the CPD.

First we plug through the wall the fiber optics elongation 
[CMTS--wall--CPD-(storage)]. It also required a ethernet connection to 
the microscope computer. For that we buy a mixed switch 10,100 and 
ethernet ports. Then the other fiber optics connects back the storage to 
the computer room through the switch, were we connect the microscope 
computer for the EPU to take the images back and do the 
cross-correlations, and also another computer could also connect the 
storage through this private network to save the data in external 
Hard-drives or other machines.

If I remember well high quality fiber optics wires could send the images 
far away. in our case is more than 150 m from the Talos-Arctica. The 
signal required for the EPU will work also with a ethernet wire as only 
small traffic is required for that purpose.

I hope this could help.
