M29504/14 & /15 Fiber Optic Termini

VIEW DATASHEET

Overview

M29504/14 & /15 termini from Amphenol Fiber Systems International (AFSI) are qualified to MIL-PRF-29504B specifications. This series of fiber optic termini provide superior optical and mechanical performance and are also 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

AFSI 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.
