Multi-fiber Optical Link for Space Applications

31
August 2021

Radiall's complete optical link is composed of Q-MTitan™ assemblies and HDQX connectors and is qualified for GEO space applications. Q-MTitan is a 12-fiber contact that fits inside the multi-cavity HDQX connector. Together, these products create high density and lightweight optical harnesses that withstand the high levels shock and vibration experienced by communication satellites. 

Q-MTitan™ Optical Contact + HDQX Multipin Connector

Satellites now use a new generation of Digital Transparent Processor (DTP) to meet the stringent demands for flexibility. Radiall offers multifiber optical links designed to meet the performance levels for density, ease of installation, weight savings and radiation resistance.

Radiall combines the ruggedized optical contacts (Q-MTitan) with 12 radiation resistant fibers to create full optical link harnesses. HDQX provides a simple way to connect up to 10 multifiber harnesses together in a single panel connector, fully tested and qualified for the severe vibration, shock and temperature cycles expected of space environments.

Q-MTitan is Radiall's high-density and ruggedized optical contact solution, capable of being terminated on round cable or ribbon fibers without needing specific accessories that would increase the overall weight of the solution. In conjunction with HDQX, it offers a secure, reliable and size-optimized solution to connect up to 120 fibers.

Qualification Summary:

  • Random Vibration: 40 Grms up to 2,000 Hz
  • Sine Vibration: 20 G up to 100 Hz
  • Mechanical Shock: 2,000 G; 10,000 Hz
  • Temp Cycling: -55°C/+125°C; 50 cycles
  • EMI: SE > 55 dB up to 18 GHz

This opens the road to more and more applications for fiber optics in space environments and justifies new developments for even higher density solutions with 24-fiber Q-MTitan interconnect solutions.
