MT Patchcords

Amphenol Military & Aerospace’s Amphenol Fiber Systems International (AFSI) MT Patchcords are high‑density MT‑to‑MT fiber‑optic cable assemblies engineered for modular optical interconnects within rugged enclosures and embedded systems. Each assembly uses precision MT ferrules to deliver multiple optical channels in compact form for space‑constrained chassis and optical backplane architectures.

Key Design and Performance Features

• Connector Interface: MPO/MTP‑style MT ferrules available as Physical Contact (PC‑MT) or Expanded Beam (EB‑MT) interfaces.
• Optical Channel Counts: 12 to 48 fibers for PC formats, with 16 and 32‑channel options for EB configurations.
• Fiber Types: Supports singlemode and multimode (OM1–OM4) fibers for broad system compatibility.
• Polish Options: APC (Angled Physical Contact) and UPC (Ultra Physical Contact) terminations for optimized return‑loss performance.
• Cable Options: Bare ribbon, PTFE‑jacketed, or polyolefin‑covered variants to suit specific routing and protection requirements.
• Mechanical Configurations: Male or female pin‑clamp variants, MPO gender options, and selectable straight or reversed polarity.
• Quality Assurance: Factory‑terminated, insertion‑loss tested, and 100% endface‑inspected for plug‑and‑play integration.

Integration and Application Context

MT Patchcords serve high‑speed optical links within embedded computing modules, rugged servers, electronic warfare hardware, and C4ISR systems. Their compact design supports high‑channel‑count interconnects in conduction‑cooled and VITA‑compliant chassis while ensuring repeatable alignment in tight packaging environments. Engineers can specify fiber type, length, polarity, and endface geometry to match optical performance and mechanical layout requirements.

System Compatibility

The assemblies interface directly with Amphenol’s circular MT connector systems—including THDM and VITA 87 families—and are suitable for use in open‑architecture VPX and SOSA‑aligned optical backplanes where ease of serviceability and density are critical. Custom lengths and protective jackets can be selected to match routing and environmental constraints within enclosures or laboratory setups.
