Sealed, lens-array fiber optics for harsh environmental applications plus GFOCA hermaphroditic. GFOCA is the industry-standard for long-run battlefield data links. Glenair signature Eye-Beam™ Power, Eye-Beam™ GMA, and Eye-Beam™ GLT are easiest-to-clean expanded beam designs.
Commonly used in harsh environmental applications such as directed energy weapons, long-run battlefield communications, and Free Space Optical applications, Glenair Expanded Beam fiber optics virtually eliminate field maintenance and cleaning difficulties, with low dB loss mating system performance rated to 1000-2000 cycles depending on fiber media selection.
Rugged Field and Expanded Beam Fiber Optics: Eye-Beam GLT, GMA, and Power Plus GFOCA D83526
Glenair supplies four different expanded beam fiber optic interconnect systems. PRIZM® MT expanded-beam technology is covered in this catalog’s MT chapter. The remaining three, Eye-Beam™ GLT, Eye-Beam™ GMA, and Eye-Beam™ Power, are covered in this section and are optimized for reliable, low-maintenance performance in the wide range of ground / air applications. Eye-Beam™ GLT is a grin-lens termini solution, Eye-Beam™ GMA is a workalike for the popular HMA hermaphroditic connector system, and Eye-Beam™ Power is a ruggedized, high optical power terminus design for directed energy and Free Space Optical applications. GFOCA hermaphroditic F/O interconnects are also presented in this section. This series, built IAW MIL-DTL-83526 and is equipped with MIL-PRF-29504/16 type termini. The GFOCA is one of Glenair's most ruggedized field-deployable fiber optic platforms.

Expanded Beam Eye-Beam™ Power Rugged, High-Power Fiber Optics for Directed Energy and FSO Applications
Eye-Beam™ Power utilizes a novel expanded optical beam approach to create a robust and stable optical connection in any environment. The industry-standard size #8 contact module allows Eye-Beam Power to be loaded into a multitude of connector form factors. This 20W and higher optical power solution is compatible with standard polarization-maintaining 1064nm fiber. 1550nm and other wavelengths can also be supported. The Glenair expanded-beam termini experiences low temperature rise at peak power, minimizing the need for additional heat sinking or thermal management beyond that of a simple copper wire overbraid.
- Size #8 drop-in expanded-beam optical contact
- Powerful 20W and higher optical contact ideally suited for directed energy applications
- Compatible with 1064nm polarization-maintaining fiber with a 0.5 dB typical insertion loss
- Low temperature rise at peak power
- Signature assembly process optimizes optical alignment for mission-critical reliability
