Multimode Fiber termination question

I have a pair of fiber cables each with SC connectors on the end. I'm wanting to figure out some way to convert these to LC terminations in order to plug into an LC based fiber switch? This is only a 30 foot patch cable so I can buy another 30 foot fiber patch cable but I'm trying to see if there are adapters so I don't have to pull another patch cable through my conduit?
 
What Spidey said .... plus: There are adapters available.

SC/LC might be a little tricky, because the LC is a much smaller connector and there may not be room for the SC connector in the surrounding real estate. If you have an LC/LC jumper, maybe you could put an LC-->SC adapter on it.

An SC/LC jumper and a coupler is probably your best bet (after just buying a new 30' SC/LC jumper).

Good Luck

Honestly, I don't know why I didn't think of that. Why is it that fiber terminations aren't all the same connectors like RJ45's are for copper?? Is there a reason for this? Sorry this sounds dumb, I'm just starting to get into fiber optics.
 
If your messing with fiber I highly suggest you take a class on it. There is a lot of info out there you need to know. Most specifically NEVER look into the optic or a fiber cable, it can and will damage your eye.

There's different sizes, differrent bandwidth, different everything.

As far as why the different connectors it's just the evolution of the technology. LC has pretty much taken over ST/SC/MTRJ because it's much smaller. For example I can fit 48 ports of 1000 Base X on a single blade in a switch/router.

The plug/termination is also very important due to how much that coupling attentuates the signal. As the manufacturing and termination technologies advanced they were able to cheaply make a high performance and small junction.

-edit- in your example you have more junctions than normal, but because of the short distance you'll still be plenty fine.
 
To make a long story short, in my company there are 3 outdoor buildings that all need network connections. When I was first hired everything was run with copper (copper run outside with NO grounding). I haven't been doing this myself but over the past year I've had a 3rd party company come in and slowly replace the copper wire with fiber optics. 2 of the buildings now are completed with multimode fiber running to them and each are terminated in a fiber optic box with ST connectors. I have one more building left to wire up but it's only a 25' run so I'm just going to have a patch cable run out to it because this building will only be there for about another year so I don't want to invest all the money in it now only to change it in another year. The reason for the change in terminations is because I also just received a fiber optic switch rather than using our current fiber optic to ethernet converters. I know it's not the perfect situation but it's better than what was originally in and in the end (still not finished) everything should be up to par.
