Om det blir problem så kan man alltid svetsa fast en "gammaldags" svans (med kontakt) i stället.Frågan är om det i längden är billigare att svetsa på en gång än laga om dom mekaniska skarvarna som man får problem med.
Finns det tillgängligt material om att det kan bli problem?http://lw.pennnet.com/display_article/43143/13/ART CL/none/none/1/Optical-gels-improve-fiber-optic-co nnectors-and-splices/Another approach to the permanent mating of optical fibers is the mechanical splice, with or without an optical gel. Both can be assembled without expensive tools. A dry mechanical splice must still be designed to form a zero gap, a constraint which demands tight and costly engineering tolerances, not only on the parts but also in the cleaving, polishing, and splicing operations. A mechanical splice with an optical gel is often a better solution.
When vibration, thermal expansion, or mechanical shock cause the fibers and structural parts of a connector to move, large stresses can be induced in the fibers. In a dry connector, if microscopic fiber motion is constrained under high stress, the fiber can fracture. Alternatively, if the design allows excessive motion, then the fiber-to-fiber air gap may become enlarged. An optical gel in the gap trumps this unhappy tradeoff. Since gels are viscoelastic, they can take up mechanical tolerance "stack-up" in other parts, and relieve stresses by expanding or contracting without delaminating at the fiber endfaces and breaking the lightpath. Gelled mechanical splices win on cost, and ease-of-assembly. In severe environments, the mechanical pliability and sealant qualities of a gel help ensure reliable, long service life.

While they may likely have fewer re-mate cycles than dry connectors, gel connectors may excel in reflection performance because they ensure intimate mechanical contact, particularly after many re-mate cycles, when wear-out may alter critical dimensions and degrade the performance of a dry connector.
Det som artikeln inte nämner är problem med optiska gelet. Gelet kan torka ut, bli ogenomskinligt eller läcka ut över tiden.
