A key feature of outdoor connectors is their ability to protect against the intrusion of dirt and water, as well as their resistance against vibration.

They can also transmit optical and electrical signals, as well as contain properties that make it suitable for both analogue and digital applications. The product is compatible with different optical fibre types and benefits from excellent optical and mechanical characteristics. All of these qualities can be found in the new Diamond Multipurpose DM4 insert, which is specifically designed for use in various outdoor and industrial connector types.

Outdoor and industrial conditions are much harsher than the ones typically endured by standard commercial connectors and cable assemblies. Harsh environmental surroundings can adversely affect the operation of a system using fibre optics. To combat these conditions, Diamond has developed a wide range of strong, reliable and customisable optical interconnect solutions built around the innovative Diamond Multipurpose DM4 insert.

The DM4 Insert incorporates four optical or electrical termini ideal for hybrid electrical / optical applications. The optical termini are assembled with Diamond’s active core alignment (ACA) process, allowing for a combination of excellent fibre core concentricity and superior optical performance. In addition, IP ratings are met through solid connector construction with fortified ingress protection.

The new insert is the core of the existing HE-2000, MIL-38999 DM and MIL-83526 DM Diamond connectors. Furthermore, the DM4 insert is constructed to fit into a vari ety of different connector housings. Compatibility with tight cable and semi-loose cable /fibre construction is ensured. Based on a 2.5mm fibre optic ferrule, the DM termini uses integrated springs to avoid contact interruptions, which allows for quick and easy assembly and repair.
