for Fiber Optic Termini
MIL-PRF-29504 (General Specification for Fiber Optic Termini) testing aims to qualify removable crimp and epoxy type fiber optic termini (singlemode and multimode). Both the pin and socket components are tested. Qualified termini per this performance requirement can then be used in MIL-PRF-28876 fiber optic connectors to make flexible mating and un-mating possible.
MIL-PRF-29504 termini must be able to withstand 10 G’s of vibration (ex. TIA/EIA-455-11) and over 1000 G’s of shock (ex. IEC-61300-2-9); testing to these conditions is not necessary for commercial use of the product. Both Vibration and Shock test the mating durability of the samples. Mating Durability testing per MIL-PRF-29504 mates and de-mate the pin and socket termini to test optical signal strength. The removable crimp and epoxy type allows the termini to be used in a variety of connectors – MIL-PRF-28876 is one example – and other fiber optic components. Termini can range from sizes 4 to 5 and 14 to 20 as per their applicable slash sheet specification and dimension documents.
Testing per MIL-PRF-29504 primarily focuses on the termini’s resistance to certain climates, durability, and dimensions. There are many demanding connection opportunities to be made while on board a naval ship. In order to meet these demands, a test such as Fiber Pull Out Force that tests the samples’ resistance to a heavy pull that simulates a connection disturbance. At times MIL-PRF-28876 connectors must be connected in such a particular manner such as right angle installation, straight connection, etc. A typical fixed setup for plug and socket connectors (as seen in MIL-DTL-83526) would limit mating and un-mating capability. The termini described in MIL-PRF-29504 are capable of installation and de-installation that gives many different combinations of plug and socket (receptacle) setups to meet the conditions to establish a connection for the two connectors (MIL-PRF-28876).
