Splicing is one of the important factors in a fiber optical system. The information given in the web page is not broad enough to assist technical and business people in their search for additional information.  It appears that the information on splicing was focused only on single mode fibres.  But there are actually a variety of splicing techniques that exist according to the book "Fibre Optic component design fabrication testing, Operation, Reliability and Maintainability".  The some of the splicing methods this web page lacks are Elastomeric Splice, Rotary Splice, Silicon Chip array Splice and Rapid Ribbon Splice.  People who surf to find out about these splicing techniques will consider this as a priliminary Web Page, because of the limited factors in the site.  The factors that are important to those people are Splice Test, Splice Failures and Splice Critical Design Criteria.
 
Splice Tests:
    Fibre splices are affected by environment and mechanical conditions.  This might increase the fibres optical loss. So  environmental tests are performed on the splices by their manufacturer.  Commonly the attenuation of a completed splice is measured before and after the environmental testing is performed and a comparison between those two readings are made.  The difference is taken as a measure of the splice sensitivity to the test condition and the prediction of its performance in the field.  The common tests done in the optical splices are:  Insertion Loss, Salt Spray, Fluid Immersion, Impact, Operating Temperature, Thermal shock, Humidity, Temperature Life, Tensile Loading, Mechanical Shock, Vibration and Temperature Cycling.

Splice Failures:-
    Failure is a huge problem in fibre splicing, this is barely talked about in the site.  Failure mechanisms may cause long term effect in splices, that includes the breakdown of the index matching fluid, separation of the fiber endface and the index matching fluid and fibre movement in the lateral and axial directions.
    The information given about the index-matching epoxy in V-Block, Precision Sleeve and the 3-Rods splicing, are superficial. They barely mention the environment factors involved due to the exposure of epoxy in the work space.  Mainly the breakdown of  the index matching fluid is induced by exposing the joint in cold and hot temperatures.  Some materials become stiff in cold temperature or become thin in hot temperature.  Other things that are most likely to cause the failure mechanisms are: Bad Cleaves, Fibre breakage, Fibre endface separation due to improper assembly, Dirt, Vibration and Improper assembly techniques.

The above table is a list of design characteristics which should be considered before using any of the splices.  The data in the table contains typical values taken from a manufacturer's data sheets.  The actual time required to complete the splice is a very important factor which may attract the business people.  For an additional business information they could have mentioned about the storage methods and the cleavering tolerance.
