SHEATHED OPTICAL RIBBON CABLE ASSEMBLY

A cable assembly comprising: (a) a ribbon cable having a plurality of optical fibers having endfaces; (b) an elastomeric sheathing being disposed over at least a portion of the ribbon cable and terminating in a sheathing end near the endfaces such that the endfaces protrude beyond the sheathing end; (c) a ferrule having a mating surface presenting the endfaces, and a rear end having a rear opening through which the optical fibers pass, the rear end contacting the sheathing end to form an adhesive tight seal sufficient to prevent liquid adhesive in the ferrule from flowing out of the rear opening; and (d) adhesive disposed in the ferrule to secure the optical fibers to the ferrule.
