If i need to connect 2 cisco 2960S switch over fiber with over a distance of 200m, i know if have to use GLC-SX-MM but how many cores do i need ? to be honest i dont have understanding of when we need to use how many cores ?
Can someone help me understand in which case do we need 2 core or 6 core fibers ?
Solved! Go to Solution.
No sure what you mean by core, but usually the fiber count is by strands or pair. So to connect 2 switches together you need a pair of fiber which is equal to 2 strands.
Basically Sir, there was a discussion a while back about the design of our headoffice network. We are discussing how many core of fiber we needed from every floor to 3rd floor where the aggregation switch was placed (it was 3560 24 with SFPs). At that time our vendor told us to deploy 6 core fiber from every floor to 3rd floor for uplink purpose.
Thats why i asked,
Thanks alot Reza bhai (dont mind if i call you bhai). Sir kindly correct me that always one core (or one pair) is needed for a connection to be made ?? am i right ?
Sir i read an expert saying that you are almost an authority over VSS (outside Cisco). Can you comment on my post on 4500 SUP 8-E
Can you copy and paste the URL for that post?
Unfortunately, I can't common about this, as this sup is pretty new, but I am sure, Marvin has provided you the correct info.
In general and I think, VSS will be supported in all Sups going forward. Now, if it is not in the current version of software, I am sure it is on road map.
1 core = 2 pairs
Me bad. It's 2 cores = 1 pair.
"Core" is being used in the Australian jargon.
To make things less confusing, the term "pair" is universal.
