Lumiére Fibre Optic Termini (ELIO®)
Tech Optics offers the AFSI Lumiére fibre optic terminus for commercial airframe, avionics and aerospace applications. AFSI’s Lumiére termini are a direct replacement for ELIO® termini and are compatible with existing ELIO® connectors. This fibre optic contact utilizes a 2.5mm diameter field-proven ceramic ST type ferrule, which can be inserted into a size 16 cavity.
The terminus is hermaphroditic allowing the use of the same contact in the receptacle or plug. In addition, the contact is available in both multimode and single mode versions. An anti-rotation feature allows PC, UPC and APC polishes. Because the Lumiére features a standard ST type ferrule, well known procedures and readily available tools can be used for termination. Long and short boot versions are available to support multiple connector types.
Amphenol also manufactures a full line of EN-4531 and EN-4165 rectangular and cylindrical connectors to house the Lumiére termini.
Features- Hermaphroditic style allows one contact type
- Standard 2.5mm ST type ferrule interface allows the use of standard termination procedures and readily available tools
- Simple access to optical termini facilitates cleaning
- Options available for single mode and multimode fiber
- Pull proof option allows the use of the terminus in a connector without a backshell
- Supports both tight or loose structured cable
Applications
- In-flight entertainment systems
- Avionics
- Heads-up displays
- Airframe

M29504/4 & M29504/5 Fibre Optic Termini
Tech Optics offer high quality M29504/4 & /5 style fibre optic termini providing superior optical and mechanical performance. Designed to fit into MIL-DTL-38999 Series III, pin size 16 connectors, this low cost, high precision termini family is ideal for harsh environment fibre optic interconnections. Available for single mode and multimode applications.
For example the AFSI M29K1000 and M29L1000 series termini are qualified to MIL-STD-29504/4 & /5 Rev. D. and utilize the highest quality zirconia ceramic ferrules and split alignment sleeves available. AFSI’s tight-tolerance ferrules are optimized for low insertion loss, low back reflection and exceptional durability. All ferrules are capable of standard and ultra polished end faces for those tight optical budget applications. In addition, epoxy removal and polishing times are minimized by the ferrule’s pre-domed design feature.
The socket zirconia split alignment sleeve design ensures accurate physical contact, fibre-to-fibre alignment and guarantees the highest performing connector of its kind for use in a variety of demanding environmental conditions.
M29504 fibre optic termination system offers precise, superior and reliable connections over repeated connector mating cycles and through a wide range of harsh environmental conditions.

M29504/14 & M29504/15 Fibre Optic Termini
M29504/14 & /15 termini from Amphenol Fiber Systems International (AFSI) are qualified to MIL-PRF-29504B specifications. This series of fibre optic termini provide superior optical and mechanical performance and are compatible with M28876 and comparable military-style connectors.
Unlike other M29504/14 & /15 designs, AFSI’s product is precision-engineered, allowing the ferrule to press fit and bottom out within the terminus bodies. This strict tolerance management eliminates loose fit or epoxy construction and yields better overall performance under stressful environmental conditions.
The M29504/15 features a ceramic alignment sleeve, maximizing its ability to hold extremely tight dimensional tolerances while maintaining accurate concentricity, providing superior mechanical and optical performance.
Options Available
Tech Optics offers a complete line of termini insertion, extraction and polishing tools, which are compatible with NAVSEA specifications. These tools can be used with AFSI M29504/14 & /15 termini or other manufacturers’ M29504/14 & /15 termini. Tools include termini extraction, termini insertion, alignment sleeve extraction, alignment sleeve insertion and single position polishing puck.
