Fiber Optic Splicing
Hello,
I am working on a project to connect some branch offices to our main office via a fiber optic cable. We are using a single-mode (OS2) cable with 24 fiber strands. I would like to know if we can T-splice the fiber optic cable. The cable would come from the main site, mid way I would like to have it T-spliced so one cable in the splice can to one branch site and the second cable in the T-splice can go to the other branch site. Is this possible to accomplish on a utility pole using a closure?

You can't T-splice a CAT5 cable in a network and have it work so I don't see how T-splicing a fibre would work any better. ??
Splicing would make no sense at all, since it are serial point to point connections.
But you can just connect it to a switch of course. This should do it.
And, there are several very interesting technologies to multiplex different protocols over one fiber connection and demultiplex them at the end point.
For instance, see here:

Simple answer - no you cannot t-splice a fibre.
As others have said , you can cut and terminate both ends , then put in some active kit to allow you then connect in a third fibre too.
My suggestion would be to run 2 new fibres , rather than splitting the existing. One from each end of both the existing sites to the new location forming a triangle (one link being one cable with multiple cores). This way you also get resilience and the ability to patch from either end or straight through should there be a failure on one leg.

Thanks for everyone's comments. Ideally it would be nice to run multiple cables and then gain connectivity through switches, and at the same time build in resiliency. Unfortunately, these cables are miles long, and are run aerial with limited space on the utility poles, and even more limited space in the duct that enters the building.
Let's call the main site A and the two branch offices B & C. The splice point would be ABC. I want to run a 24 strand piece of fiber from A to point ABC. From site B I want to run a 12 strand piece of fiber to point ABC. From site C I want to run a 12 strand piece of fiber to point ABC.
Once all cables are at point ABC, I would like to designate 12 strands from cable A to site B, and designate the remaining 12 strands of cable A to site C.
I was thinking how Verizon is able to have a fiber closure on the utility pole, and when a customer orders service they string the cable from the closure to the customer site.

Thanks Kzin_xxxx
Your are pretty much right on the money. I contacted a vendor and have the splice scheduled. He is using a fusion splicer with a .01%dB loss. Vendor is doing the splice in a bucket, and protecting with an aerial closure. WooHoo!!
thanks for your input

No problem - happy to help.
With regard to the loss , just make sure you have a measurement for each single fibre anyway , even though the claimed loss of a join may be 0.01dB - sometimes you get a duffer , and asking for measurements lets them know they will have to get them something like.
