How do I connect two HP switches via fiber optic using the SFP ports.
Hello Experts,
I have two projects where I am linking two buildings for data. I will be using pre-terminated 62.5 multimode fiber. I was thinking of going with SC connectors because this seems to be the standard lately but I can use another type if needed.
I will be using HP Layer2 switches. Most likely I will be using model HP 2520-24G-POE. I can use different models if needed but would like to keep my cost around $1,500/switch.
I've always seen SFP links on my switches and know there for connecting gig fiber or copper but I have no clue how to accomplish this. Is there just a cable I need to purchase?
So something like this:
(MDF Switch) SFP port ---> fiber patch cord ---> wall mount termination box to adapter panel ---> preterm fiber ---> wall mount termination box to adapter panel ---> fiber patch cord ---> (IDF Switch) SFP port.
What do I need and how do I connect my fiber to the switch. Would I want to use a certain connector for the fiber such as SC or LC?
In the past I've used media converters but if possible I would like to get rid of this point of failure.

If the cable between buildings is longer than the J4858C allow , you should use J4859C (up to max 550m).
They are expensive and you MUST use org. HP-labeled in HP-switch

The J4859C can do either single-mode or multi-mode fiber. That is one reason is is expensive. If you go with this, I would suggest using single mode fiber to begin with. Single mode fiber is generally less expensive than multi mode fiber since it is easier to manufacture.

Thanks for all the feedback.
So, to use the SFP ports you need to buy whats called a "transceiver" correct? Each transceiver is unique to that model of switch correct? Do the transceivers just plug into the SFP ports? The picture of the transceiver looks more like a card where on the switch theirs 4 small ports.
My fiber runs are no longer(not including patch cords) than 475 feet or 144.78 meters. So in this situation the HP X121 1G SFP LC SX Transceiver (J4858C) would be my best choice?

The SFP transceivers are usually the same for various models of switches.

The transceiver should slide right into the port on your switch.
The J4858C would be the correct choice for your needs.
