I have several rudimentary questions about fiber optics cabling & connectors. I understand the basics of MMF and SMF, and the distance factors of each for different BW ratings. I'll ask a series of questions, and hopefully gain a better "big picture" understanding of things I still get hung up on (when having to choose optics and connector options for Cisco gear):
- Do the connector types have to match on each end of a fiber cable? For example, if a module on one end of a MMF link is using LC connectors, does the other module also have to use LC?
- Similar to the above - if I have a fiber cable w/ existing SC connectors on both ends, can I safely add SC->LC patch cables to both ends (or just to one end) to plug into LC modules?
- If I have an LC->LC length of MMF, can I safely add an LC->LC patch cable to extend its distance (for example, to reach a relocated data center beyond the original termination point)?
- What exactly is the purpose of having a fiber patch panel in-between the endpoints (or at both ends - in both locations fronting the actual equipment)? Does this buy me flexibility in what types of connectors/modules I use at each end?
- example: a customer has a Cisco 2900XL switch with a fiber module (see attached - these look like LC connectors - plus, it reads 100Base-FX above ports 23 & 24), and it hooks into the displayed patch panel. On the OTHER end, the customer has a 2960G switch w/ SFP ports. If I had to choose an optics module for this unit (specifically, a WS-C2960G-24TC-L), what would be a compatible module?
I'll award points for clear answers to all of the above, OR TO A SOLID REFERENCE GUIDE that covers all of this. If I could award more than 500, I would - this is a lot of questions, I know.
Thanks in advance.
