The present disclosure describes fusion spliced cable assemblies. An assembly may include a first and a second fiber optic cable, where an end of at least a first optical fiber from the first fiber optic cable is fusion spliced together with an end of at least a second optical fiber from the second fiber optic cable, the first optical fiber having a first length of prepared fiber extending from the spliced end of the first optical fiber to a transition point of the first optical fiber, the second optical fiber having a second length of prepared fiber extending from the spliced end of the second optical fiber to a transition point of the second optical fiber, where the transition point of the first optical fiber is a distance from the transition point of the second optical fiber, and where a total length of prepared fiber is the sum of the first length of prepared fiber for the first optical fiber and the second length of prepared fiber for the second optical fiber; a support configured to engage at least a portion of the total length of prepared fiber such that the distance between the transition points of each optical fiber is less than the total length of prepared fiber of the first and second optical fibers; and a transition housing coupled to the first and second fiber optic cables and surrounding the support. Fusion spliced cable assembly breakout kits are also provided.
