Intelligent Release Inter-Connect System (IRIS)

Optical Cable Corporation (OCC) introduces a revolutionary fiber optic inter-connect system, which disengages upon impact to a traffic control enclosure. IRIS allows for a fully restored fiber optic connection, without field repair or retermination of the fiber optic cable. Most importantly, IRIS protects the installed fiber plant from damage when the control enclosure is impacted.

Designed to sense mechanical axial and shear loads from within the traffic control enclosure, IRIS's patent-pending release technology releases and separates, thereby protecting the installed fiber plant. When the sensing ring is pulled by a horizontal force within a 360° horizon, the mechanical latch surrounding the engaged fiber optic connector is tripped.

The multi-channel fiber optic connector disengages and retracts under positive pressure, thus ejecting the plug to "break away" from the receptacle in milliseconds, avoiding collateral damage by the collapsing traffic control cabinet.

  • Plug-and-play inter-connect
  • Eliminates fiber maintenance points
  • First completely dust proof and waterproof system
  • Pre-terminated to eliminate field installation time and cost
  • Minimizes collateral damage
  • Minimizes downtime
  • First true reusable breakaway system
  • No need for additional patch cords or panels
  • True backbone fiber protection

Intelligent Transportation Systems, or ITS, encompasses a broad range of wireless and fiber optic communications-based information, control and electronics technologies. When integrated into the transportation system infrastructure, these technologies help monitor and manage traffic flow, reduce congestion, provide alternate routes to travelers, enhance productivity and save time, money and lives.

Given the emphasis of increased fiber optic inter-connect within the ITS architecture, protecting and restoring fiber connectivity within the traffic control cabinet is critical (especially given the increased fiber count) to provide control as well as protect revenue-bearing services such as traffic violation detection.

Destruction of a traffic-control cabinet results in lost synchronization, productivity and time, as well as the loss of thousands of dollars to repair multiple fiber optic cables at any given intersection. Protecting the installed fiber plant with IRIS greatly reduces the impact from both financial and out-of-service conditions.


  • The IRIS system protects the investment of the outside plant by disengaging upon mechanical impact or detonation. Fiber optic service is easily restored by re-arming the IRIS connector installed within a new enclosure
  • The IRIS inter-connect system is designed to operate within uncontrolled environments and survive temporary submersible conditions. The sealing features also prevent accumulation of dust and debris, thus extending the field maintenance life cycles.
  • Mechanical detonation system enables fiber connector system to disengage rapidly and without damaging fiber optic contacts.
  • The circular sensing ring allows tethering from all four quadrants within a traffic-control cabinet.
  • An arming ring allows field service personnel to safely rearm or service the system without accidentally detonating the connector.
  • The IRIS system can accommodate up to 12 fiber optic channels. The plug side of IRIS features 6 ft. pigtails with choice of ST, SC, or LC simplex connectors. The receptacle side is purchased with choice of fiber count and length of blunt end.
  • IRIS enables efficient installation of pretested fiber optic assemblies within minutes. Though the receptacle pigtail is spliced into the fiber plant, the plug/receptacle connectors are all pre-terminated and test verified.
