Fiber questions of all types...
Posted on 2006-07-11
The client has one church, elementary and daycare at site 1 and a high school at site 2 (six miles away).
Site 1 and site 2 are connected via a point-to-point T1 @ 1.5
At site 1, there are five buildings (church, gym, admin, classrooms & daycare) all connected with cat 5 and the server room is in the church. The cabling is like this:
Cat 5 from church to gym where there is a switch...
Cat 5 from gym to admin where there is a switch...
Cat five from admin to daycare & classrooms where there are switches...
Now these are not the best switches...they are 24 port 3 COMs, 16 port SOHO and 8 port SOHO switches. So basically, the entire network is cabled by jumping from switch to switch to switch and we want to change all of that.
What we would like to do is bring in a fiber backbone and run stands of fiber from the server room straight to the individual buildings and put nice layer 2 or layer 3 PoE switches in each building to serve the PCs in there now and VoIP phones we want to install in the near future.
Here come the questions:
1. Do we run four individual strands of fiber (one to each building on a star topology) or can we run a ring and encompass all of the buildings, originating and terminating in the server room? I favor the ring and the on-staff IT guy favors the star topology.
2. Are we running single mode or multimode (all of our distances are less than 500 meters)?
3. What kind of fiber are we running? What's the "type" of fiber we need to see on the quotes we're getting? I would recognize cat5E or cat6 and the like. What do I want to see when referencing the type of fiber to be installed?
4. How many strands of glass are going to be in this fiber? In my mind, I'm seeing only one strand of glass. For this type of application, how many strands should I expect to see?
5. What other questions should I be asking? What's left off from the list above?
Thanks in advance for the help.
