I need some help on a fiber design project. I have fiber coming in from an ISP and need to put out a fiber backbone to connect to more thatn 30 locations. I need help with how you think about going about the way to do this, what i should do in the MDF, and how i should connect to the locations. Help would be greatly appreciated.
1. What type of fiber and signal (OC3, OC12, GE, Wavelength) is coming from the ISP?
singal mode fiber, have an optical router module
You should probably find this out.
2. Will the ISP connection be using BGP you have to peer with?
OK. So you have a little less to worry about with memory requirements, etc.
3. What type of fiber and distances connect the 30 remote locations?
multimode fiber and the max distance is 350 meters
If you have 62.5u MMF then you would most likey need LX/LH for longer spans. If you have 50u MMF then SX should ben OK. Check the specs per span.
4. What type of traffic patterns/QoS will be needed?
it will accomadate voice, video, and data
You should have a good QoS strategy or segregate the traffic.
5. Can the 30 locations be a Layer 3 hop or do they require other segmentation?
they need to be segmented by group
You can carve this up a number of different ways.
6. What bandwidth is needed to each of the 30 locations?
i need a gigabiy backbone and 100mb to the breakout box
Not sure where your breakout box resides but MMF GE from the main location with the ISP connection and any small switch with MMF GE and 10/100 copper at the remote end should be OK.
A generic response would be to use a 6500 for the ISP connection. Depending on the type of signal coming from the ISP you should be able to a SPA or generic linecard. Standard GE interfaces for the remote site distribution. FW or VPN blades could also be used here for extra features.
Remote sites can use something like a 3560 or 3750. This will have MMF GE and 10/100 with QoS. POE may be something you may consider as well.
You can also consider using a redundant architecture or simplex if downtime is not a concern.
We are pleased to announce availability of Beta software for 16.6.3. 16.6.3 will be the second rebuild on the 16.6 release train targeted towards Catalyst 9500/9400/9300/3850/3650 switching platforms. We are looking for early feedback from custome...
