OCC’s MIL-PRF-29504/14 and /15 fiber optic termini are designed for outstanding optical performance in extreme environments. Widely regarded as the ideal fiber optic termini for harsh environments, OCC’s MIL-PRF-29504/14 and /15 have an enhanced design that allows the terminus system to withstand challenging environmental and mechanical conditions without optical degradation.

Features

  • Multi-use termini system. Intermateable and interchangeable with other M29504/14- and /15-style termini, OCC’s M29504 termini assure conformance to MIL-PRF-29504 and MIL-PRF-28876 performance specifications to ensure compatibility and standardized termination techniques. Adapted for OCC’s EZ-MATE connectors, the M29504 terminus system allows for double the fiber-count density in the same connector versus the traditional 2.5mm ferrule terminus. OCC’s Pierside connectors also incorporate the M29504 termini.
  • Enhanced design for superior performance. The OCC M29504/14 and /15 termini design features pre-radius 2.00mm zirconia ultra high-tolerance ferrules, an enhanced cable retention using serrated crimp areas and removable captivated split alignment sleeves. By utilizing the Belleville stacked spring design, the OCC M29504 termini provide a high spring force versus longitudinal displacement in mating conditions. In addition, the M29504 has standardized termination templates and OCC has reduced the use of Beryllium copper materials.
  • Multiple fiber accommodations. OCC’s M29504 is available in single-mode and multimode configurations, a short-body option, and an environmental sealing plug for unused cavities (M29504/03-4038).
