Ok, So where I work we want to upgrade our network backbone, and thus doing so we will be installing fibre. We have been in the process of getting quotes, and so far one has come back and it seems ridiculously high. Lets take a look at one of the runs, how much do you think this should cost? Between building 1 and Building 2, there is about 15 meters of ground. The comms cabinets that this fibre needs to get between are roughly 20 meters apart (15m ground plus elevation). Between these buildings, there is a 100mm conduit that is empty, and has a pull cord. There is internal conduit up to the comms cabinets but there is no fibre tray at either end, so that needs to be factored into the cost of the install. We only want 4 core multimode (OM3, OM4 etc). Brand doesn't matter for fibre trays and can be either SC or LC. How much do you think that should cost all up parts and labour???
