I'm planning to adjoin 3 buildings with 10gbase fiber. I wanted to layout what I'm leaning towards, and had a few technical questions for efficiency and future expansion. It looks like 10gbase cost is pretty reasonable these days. I was also looking for advice for cisco equip choice.
Building A is 440ft to Building B - Planning 6 strand OM3 in conduit (4 reserve)
Building A is 1400ft to Building C - Planning 6 strand OM4 in conduit (4 reserve)
There is a central point outside I wanted to consider an accessible, buried junction box to preterminate 12 strands from Building A, about 200ft away (putting J box closer to other 2 buildings) outside. I'm not privy, but was learning about MT connectors and thought it might be good to consider for this? This way any buildings requiring fiber need only trench up to this J box. It's pretty hot where we are, and we do have a hot melt kit. It's my concern the termination types have temperature limits. The J box also serves as expansion, should we need in the future. Would a patch panel in a buried Jbox setup like this be feasible?
Any opinions on 10gbase transceivers ? (cost concerned)
Also, we thought this may be a good time to turn our DLink dumb switches into Layer3 Cisco instead of putting ugly media converters.
Can someone recommend a 48 port switch with (4) 10gigabit SFP ? Or other idea?
What about switches on the other side? Layer 3, 24 port with at least (1) 10gigabit uplink?
I was thinking about a switch with the expansion interfaces, but I know those aren't always most cost-effective. If we expand beyond the above, maybe something we can trunk on later, if we need?
Curious about experts opinions on these!!
