Expanded beam fiber optic connectors using lens-based optical coupling. The beam is expanded and collimated across the connector interface, making it inherently resistant to dust, dirt, and contamination. Ideal for tactical field-deployed fiber systems, military vehicle interconnects, and harsh outdoor environments where traditional physical-contact fiber connectors fail.
Expanded beam (lens-based)
Single-mode (SM), Multi-mode (MM)
1, 2, 4 channels
≤ 1.5 dB typical
≥ 45 dB (SM APC)
Expanded ~2mm at interface
-55°C to +85°C
Dust, mud, water tolerant
| Channel Count | Fiber Type | Connector Style | Insertion Loss | Applications |
|---|---|---|---|---|
| 1 ch | SM / MM | Plug, Bulkhead | ≤ 1.5 dB | Tactical field link |
| 2 ch | SM / MM | Plug, Wall Mount | ≤ 1.5 dB | Vehicle interconnect |
| 4 ch | SM / MM | Plug, Wall, Jam Nut | ≤ 1.8 dB | Shelter feedthrough |
Expanded beam design means the optical path is ~2mm diameter at the interface. Dust particles, mud, and water have minimal impact — ideal for battlefield conditions.
Unlike physical-contact (PC) connectors, expanded beam interfaces do not require precision cleaning. Simple wipe-down restores performance in the field.
Military-grade circular connector housing with precision lens assembly. Withstands shock, vibration, and immersion per MIL-STD-810.
Optional hermaphroditic (genderless) interface allows any connector to mate with any other. Reduces cable inventory and deployment complexity.
