Overview
Amphenol Fiber Systems International’s (AFSI) M29504/04 & /05 style fiber optic termini, the M29K1000 and M29L1000 provide 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 fiber optic interconnections.  Available for single mode and multimode applications, these termini are qualified to MIL-STD-29504/04 & /05 Rev. D.
The M29K1000 and M29L1000 series termini 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 M29L1000’s zirconia split alignment sleeve design ensures accurate physical contact, fiber-to-fiber alignment and guarantees the highest performing connector of its kind for use in a variety of demanding environmental conditions.
The M29K1000 and M29L1000 series fiber optic termination system offers precise, superior and reliable connections over repeated connector mating cycles and through a wide range of harsh environmental conditions.
