Small Form Factor MT Fiber Optic Connectors

The Small Form Factor MT Fiber Optic Connectors from Amphenol Military & Aerospace’s Amphenol Fiber Systems International division use the NanoDMT miniature D‑sub form factor to deliver high‑density optical performance in rugged applications. Each connector integrates a single MT ferrule supporting up to 64 fibers within a compact footprint suitable for constrained platforms.

Design and Construction

• Miniature D‑sub shell with precision MT ferrule alignment for consistent insertion and return loss.
• Machined aluminum or stainless‑steel housings with Ni‑PTFE or black zinc‑nickel finishes for corrosion resistance.
• Conductive O‑rings providing EMI mitigation and IP68 environmental sealing.
• Three‑tier mating design with sub‑alignment pins and insert‑to‑insert bottoming delivering repeatable ferrule positioning.

Performance Attributes

• Supports single‑mode and multi‑mode fibers with APC or UPC polishes.
• Typical optical loss near 0.3 dB and return loss > 60 dB for single‑mode channels.
• Validated to MIL‑STD‑202 and MIL‑STD‑833E shock and vibration tests for rugged operation.
• Compatible with panels up to approximately 3/16 inch thick and adaptable strain‑relief options for ribbon or round cables.

Configurations and Accessories

• Plug (DMTP) and Receptacle (DMTR) interfaces for modular harness design.
• EMI Cover (DMTE), Dust Cover (DMTD), and Replacement Screws (DMTS) available for field service and protection.

Applications

• High‑speed display and sensor interconnects
• Rugged servers and network switches
• UAV, missile, and modular radar systems
• Outdoor and military data networks requiring compact multi‑fiber links

By combining MT ferrule density with a miniature rectangular shell, these connectors deliver reliable optical connectivity and EMI shielding in the most demanding environments.
