About the M29504
Amphenol Fiber Systems International’s (AFSI)
M29504/4 & /5 style fiber optic termini, the
M29K1000 and M29L1000 series, provide superior
optical and mechanical performance. Designed to fit
into MIL-DTL-38999 Series III, pin size 16 connec-
tors, this low-cost, high-precision terminus family is
ideal for harsh environment fiber optic interconnec-
tions. Available for single mode and multimode
applications, these termini conform to the rigorous
conditions of the MIL-PRF-29504D specification.
The M29K1000 and M29L1000 series termini utilize
the highest quality zirconia ceramic ferrules and split
alignment sleeves available. AFSI’s tight-tolerance fer-
rules are optimized for low insertion loss, low back
reflection and exceptional durability. All ferrules are
available in 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.
