    MIL-38999 DM4 Family

Vibration resistant interconnect solution

Diamond has developed an advanced COTS MIL-38999 connector that demonstrates exceptional performance in demanding optical applications. For the first time, rugged 38999 connectors are available for use with small-core single mode fiber, polarization-maintaining (PM) fiber, and other specialty fiber types.

Built around the innovative DM4 (Multipurpose Termini), the connector incorporates four termini with Diamond's two-component ferrules, assembled with the company's Active Core Alignment (ACA) process for unparalleled core concentricity. Also available are electrical contacts for hybrid electrical / optical applications. Furthermore, Diamond splice-on termini for repairs can be field terminated with the Diamond ZEUS D50 HE fusion splicer.
