MIL-PRF-29504/14 & /15 Shipboard Optical Termini

Since 1997, MIL-PRF-29504/14 & /15 has provided dimensional and environmental requirements of what constitutes a fiber optic terminus appropriate for US Navy shipboard use, leading some to the conclusion that all qualified product is as good as another. However, as a performance-based specification, subtle differences of design and product realization, as well as latitude in the interpretation and reduction to practice of both MIL-STD-790 and the Navy’s MIL-STD-2042 specifications, leads to different optical and reliability performance of what appear equivalent competitive offerings on the Qualified Material List (QML-29504-QPD). In this paper, we explain these subtle differences of design and product realization and the corresponding impact to cable assembly yield, optical performance and reliability in the Navy shipboard harsh environment.

Expanded Beam versus Butt-Coupled Connectors

When it comes to the design of fiber optic connectors for harsh environments, two schools of thought dominate the market: Butt-Coupled or Expanded Beam Designs. Each approach has its own advantages and disadvantages and the choice of the ‘best’ connector can be blurred by the specifics of the application environment and unique requirements of the systems design. In this white paper, we explain the difference between these two technologies and present the basis of a systems engineering design guide to assist in the specification of reliable and cost effective fiber optic connectors for harsh environment applications including: Tactical, Shipboard, Aerospace, Geophysical, Railway, Video Broadcast and Power Generation. Key topics of this design guide include: Insertion and Return Loss, Mating Durability, and sensitivity to Thermal and Mechanical extremes.
