Fiber connection on cisco switch and POE switch
I have a Cisco Catalyst 4507R switch and a few other Cisco 2950 and 3560 switches. I'm expanding my network (data and voice) into another office in the same building on another floor. The new office on the other flooor will have voip, existing floor has digital phones. I need to have a fiber connection run into the new office space. These are the questions I need to have answers for:

1. What type of fiber cable do I need to run from the cisco switch to the new switch I need to purchase for the new office space? Do I run it from the 4507R switch? On that switch there are 4 fiber ports, two are already being used to connect to 2 other 3560 switches. Do I just purchase a new fiber cable to go from the 4507R to the new switch, what type? I woudl need about 300 feet or so.

2. What type of poe switch should I purchase for the new office space. I'm looking at a Cisco Catalyst 2960-48PST-S - switch - 48 ports - managed - rack-mountable? This switch will also be used to power the IP phones.

Attached is a picture of the 4507R switch that has 2 free fiber ports available (I assume I would use that one?), the other 2 with the fiber cables in them each to to a different 3560 switch.

Anything else I need to think of?

I'm not a CCNA, but I do have some working knowledge of Cisco products that should get you started.

1. It does not appear that the two types of fiber currently on your 4507r and the ones shipping on the 2960 will be compatible. After a brief search of cablestogo.com they did not offer any 90-100 meter fiber cables. What I'm getting at is if you cannot find the cable its useless to look into purchasing a fiber addin card for either switch to enable compatibility.

2. Thats a great base switch. We currently run these at our remote sites with ip phones.

The 4507r are a little out of my experience range. Hopefully this will at least spur some more comments from the other experts.

Thanks. My current 2950's are connected to the 4507R using that fiber cable in the photo, so I would think the new proposed 2960 would connect as well, no?

Based on the photo, you have multimode fiber cables installed, but just to be sure, run a "show interface status" on the 4507R and post the lines for Gig1/1,Gig1/2,Gig2/1,Gig2/2.
If those are in face 1000Base-SX GBIC modules, you'll need a GLC-SX-MM module in the new switch.

If a professional will run the new cable in the building, then you'll need 2 patch cords between the fiber patch panel and the switch modules. The 4507R uses SC connectors, the GLC-SX-MM uses LC.
If you plan to install the cable yourself, you'll need one with SC on one end, and LC on another (probably multimode cable, depending on the "sh int status" output). Some companies can make you such cables in custom lenght, but pulling fiber cables can be tricky in buildings.

Thank you Tamas.
Below are the commands you requested. Also attached is a photo of the two 3560 switches, those fiber cables on the 3560 are coming from the 4507R. The yellow cable (not sure what it's called) I think, but not sure, they are connected between the two 3560's. Do you see that port on the bottom 3560, it looks like there is a modulke not being used in there.

Based on this information and the photos what do I need to connect my network to a new Cisco 48 port POE switch in the other suite on another floor?

Will this switche sufffice?

Networking is the process of connecting computing devices, peripherals and terminals together through a system that uses wiring, cabling or radio waves that enable their users to communicate, share information and interact over distances. Often associated are issues regarding operating systems, hardware and equipment, cloud and virtual networking, protocols, architecture, storage and management.
