CSP Fiber Optic Traffic Cabinet Connectivity

CSP Fiber Shear Direct Connect Technology protects cabling infrastructure by preventing stress applied to the cable in a typical hard wired connection. CSP allows the cable to be control sheared at the base of the cabinet or structure, preventing stress on both the cable in the ground and the cable connecting to the electrical device. This innovative technology guarantees that all cabling infrastructure remains intact during an accident and enables cabinet or device restoration to take place within minutes of the equipment being reset. This Patent pending, made in the USA, innovative device was designed to eliminate patch cords, redundant maintenance and additional failure points, ultimately saving cost.

CSP Fiber Shear Technology

CSP Fiber Shear Technology is a new and improved fiber optic cabinet termination device developed specifically for Department of Transportation (DOT) traffic cabinets and roadside nodes.


Installation of CSP:

  • Eliminates the need for patch cables, replacing them with direct connect outdoor rated fiber fan-out.
  • Eliminates secondary maintenance or failure point connections in the cabinet.
  • Phases out unnecessary circuit losses.
  • Reduces overall loss by as much as half a dB.
  • Guarantees a stress-free break-away in the event of a traffic incident.
  • Ensures rapid restoration with a single fixed and pre-configured emergency splice chamber.
  • Offers easy installation with multiple mounting options. (pad mount or cabinet wall mount)
  • Provides ordering options in 50 foot increments of 2 fiber, 4 fiber, 6 fiber or 12 fiber drop cable configurations.
  • Allows for pre-installed drop cables for splicing the interconnect in the CSP splice chamber.
  • Allows for mid-span access module to convert existing cabinets without disabling the fiber circuit.  
  • Satisfies Country of Origin requirements with 100% of the device made in the USA with recyclable components.
  • Reduces warehouse inventory with the all-in-one delivery package reducing space.
  • Includes all hardware for complete installation.
