MIL-PRF-29504: General Specification
for Fiber Optic Termini
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).
