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.

Innovative Expanded Beam Termini Deliver Optimal Performance in Harsh Environments
Eye-Beam™ GLT Expanded Beam fiber optic termini can be integrated into virtually any circular or rectangular connector package. Factory terminated lens pin termini and lens socket termini on cable jumpers allow for easy fusion splicing in the field.
- All the benefits of an expanded beam connection system built into a versatile fiber optic terminus
- Factory-terminated Eye-Beam™ GLT termini easily integrated into any connector package
- Innovative expanded beam lens terminus expands signal 27X from a standard 9.3 micron fiber core
- Revolutionary design delivers low dB loss performance (1.5 dB multimode, 2.0 dB singlemode untuned) while reducing maintenance, inspection and test costs
- Ultra-high precision ceramic sleeves and custom designed terminus bodies ensure axial alignment
MIL-DTL-83526 HMA type Eye-Beam™ GMA Ball-Lens Expanded-Beam Fiber Optics
Eye-Beam™ GMA is the Glenair HMA-type harsh-environment expanded-beam fiber optic connection system with industry-leading insertion/return loss performance and mating durability. Built IAW MIL-DTL-83526/20 and /21 and fully intermateable with standard HMA type solutions.
- Field-deployable system for both indoor and outdoor applications
- Beam expansion dramatically reduces loss due to contamination
- Large ball lens facilitates easy cleaning
- Fully intermateable with all MIL-DTL-83526/20 and /21 compliant connectors
- 2 and 4-channel insert arrangements
- Singlemode and multimode versions, plus broad support for a wide range of standard and tactical military cables
NOTE: Eye-Beam™ GMA connectors are sold as parts of complete assemblies. Individual connectors require specialized termination, assembly, and cleaning processes. Customers are advised to consult with Glenair's fiber optic application engineering team before purchasing.

Expanded Beam Eye-Beam™ Power Rugged, High-Power Fiber Optics for Directed Energy and FSO Applications
A major impediment to high-power laser system deployment has been the lack of a connectivity solution to facilitate component replacement of fielded units. To address this issue, Glenair is pleased to introduce Eye-Beam Power, the first ruggedized, high-power, singlemode fiber optic contact for multi-channel connectors. Eye-Beam Power connectors are fabricated in-house with a signature laser-welding manufacturing process that yields reliable assemblies meeting the most stringent Mil-Aero industry requirements. Our process results in a robust, singlemode fiber coupler with typical losses of less than 0.5 dB, continuous optical power levels of at least 20W, stability over temperature, and easy adaptability to different single-mode fiber types and wavelengths. For polarization-maintaining fibers, our process typically results in extinction ratios better than 18 dB, with higher extinction ratios achievable if required. The versatile Eye-Beam Power optical system allows Glenair to manufacture mode size converters for switching between different sized fibers.
- 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
Harsh-Environment, Field-Deployable GFOCA Fiber Optic Connection System
Most commonly used by the army for long-run battlefield communications, the GFOCA Connection System is also well suited to dockside naval communications, down-hole drilling and other harsh environment applications. The hermaphroditic system utilizes low insertion loss butt-joint termini and a ruggedized coupling mechanism for reliable, repeatable mating. The genderless mating system is rated to 1000-2000 cycles depending on fiber media selection.
- Low insertion loss genderless termini.
- Ø 2.5 mm ceramic ferrules and alignment sleeves.
- 4 channel singlemode and multimode configurations.
- Designed to meet the interface requirements of MIL-PRF 29504/16 and /17 and MIL-DTL-83526/16 and /17 (draft revisions).
- Discrete components or complete cable-on-reel solutions available.
