MIL-C-83522 Mil Spec Optical Connectors

MIL-DTL-83522 Optical Connectors

CONTACT US TO REQUEST A QUOTE

Gemini Electronic Components presents its family of QPL Military ST Connector and ST Adapter products. The OCC family of qualified MIL-C-83522 products represents the most comprehensive line of Military Grade products available to the industry and features non-optical disconnect, nickel-plated brass, or stainless steel configurations, available in both ST and ST Adapter configurations. The MIL-C-83522 qualified family of products features a highly durable, individually mounted connector system that withstands extreme temperature change, shock, vibration and corrosion, which are typical of the extreme environments or uncontrolled operating conditions the system is designed to operate within. Ideally suited for the harsh, unprotected environments of aircraft, spacecraft, shipboard and land-based applications, this connector meets or exceeds 100% of the requirements of military specification MIL-C-83522.

The Military ST Connector is available in either a locking (ANX, ANY) or non-locking model (DNX, DNY) orientation and uses a convenient screw boot feature that eliminates the need for a cumbersome boot tool. The locking model features locking washers that prevent accidental optical disconnects, making the connector less sensitive to cable pull force or constant mechanical shock or vibration. The non-locking model features a higher force spring that reduces sensitivity to mechanical shock. In both models, a keyed bayonet latch provides easy engagement and disengagement. The zirconia ferrule is engineered to meet the requirements of MIL-C-83522/16, which ensures backward compatibility with legacy transceivers and ensures loss repeatability. A military part number identifies each connector.

Features & Benefits:

• Qualified to MIL-C-83522 ensures highest performance for single terminus (ST) connector
• Available in Nickel Plated Brass or Stainless Steel options
• Screw-on Boot provides easy installation without any boot tool
• Pin Body Locking Option prevents optical disconnect during high shock, vibration environments
• Pre-Radius Ferrule is compatible with Legacy Systems
• Enhanced Kevlar Retention allows for over 50 lb-ft of pull strength without damage
• Accommodates a broad selection of fiber optic cables
