MIL-38999 DM4 Fibre-Optic Connector

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 fibre, polarisation-maintaining (PM) fibre, and other specialist fibre types.

Built around the innovative Diamond Multipurpose (DM) insert, 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 E/O applications.

Furthermore, Diamond splice-on termini for repairs can be field terminated with the Diamond ZEUS D50 HE fusion splicer.
