Please log in for more thread options I am dimithri and I am trying find out if I can use a piece of single mode fiber to setup a network over 400m. I was told by a supplier that using a single mode fiber for such a short distance will cause data loss, however that particular information isn't reliable as he is trying to sell me a multi mode cable for the task. Therefore I would like to verify if indeed this is the case and what equipment I may require. The reason I am trying to use a single mode cable is that I already have a piece left over from another task. Also the network will be an Ethernet one therefore I am not sure what interface equipment is required from the Ethernet router to the optic cable. _________ __________ ________ | | | | | | | | Fiber cable | | Fiber cable | | |computer1|---------------------| computer2 |------------------- | server | | | 400m | | 400m | | |________ | |__________ | |_______ | Basically the above diagram shows what I want to do. My cable length is 840m. I want to get information from computer1 and 2 to the server. Any help with this will be greatly appreciated. Thanks in advance. Dimithri | |||||||||||||

You can certainly use SM for this but the ethernet cards must be SM as

All I have is the single mode cable. I will need 4 Ethernet to fiber converters (not sure what the exact name is) for single mode. If I go with the multi mode setup I would need 1km of cable aside from the converters. I am not sure how that works out, meaning if getting four MM converters and a cable is cheaper than getting 4 SM converter. Thanks again, Dimithri | |||||||||||||
