LEVITON Network Solutions Fiber Raceway System Application User Guide
Introduction
The Leviton Fiber Raceway System (FRS) provides a robust solution to route,
protect, and store fiber cabling in data centers, head ends, telecom rooms,
and wiring closets.
Application Note ID: NA-AN-23-005-05-09-23
The system is comprised of solid or slotted duct sections, horizontal and
vertical elbows, tees, and cross sections all of which are connected via
simple joiners. Side drop-offs and trumpets along with optional tubing kits
provide a transition to vertical management or rack infrastructure. FRS
components are available with or without covers.

Duct mounting kits provide flexible options to mount the Fiber Raceway System
to the building structure. Mounting kits are available to support common
mounting scenarios including wall-mount, under-floor, above rack, ladder-rack,
Unistrut, and ceiling suspension applications.
Product Line: Fiber Raceway
Part Numbers Affected: Fiber Raceway System
Planning & Design Considerations
A detailed floor plan is necessary to create a successful Fiber Raceway design. Begin with a floor plan that includes cabinet and rack placement, ceiling height, and any HVAC or other pathway restrictions.
Consider the size and volume of fiber or copper cables to be routed within the system. Refer to the capacity charts (below) or perform fill-rate calculations to ensure the necessary capacity is available. Select duct sizes that meet the required capacity considering the need for future growth which will ensure the planned pathway is sufficient for current and future demand.
Identify transition and drop-off requirements taking into account the volume of cabling that needs to be supported at each transition point. Transition points and drop-offs can be added later if requirements change, but it is best to plan a minimum of one drop-off for each rack or cabinet initially.
Identify mounting requirements and select the type and size of mounting kits required. Mounting kits should be placed no more than 3 feet (0.9 meters) apart when supporting fiber. For Copper cabling plan a maximum of 2 feet (0.6 meters) between supports. For high fiber volumes or armored cabling reduce the distance between supports to 2 feet (0.6 meters).
Plan the intended system layout first to determine an accurate measure of the
length of ducting needed. Then
calculate the number of duct sections (to meet the length requirement),
joiners, mounting kits, transitions, and dropoffs required. Leviton recommends
including 5-10 percent additional duct sections and joiners to account for
scrap produced when sections are cut to size and to account for any
inconsistencies between the site and the plan documents.
Demand for Fiber Raceway components is project based and as such components
are not typically stocked in large
quantities, but instead manufactured to meet demand. Ensure orders are placed
early to allow 6-8 weeks for delivery of materials from our US Distribution
Facilities (contact your Leviton Representative for urgent requirements).
Fiber Raceway System (FRS) – Duct Sections and Joiners
Leviton FRS components are designed to join together quickly and securely.
The System includes two types of ducting: slotted and solid.
Slotted ducting has pre-cut slots on each end allowing each section to be snapped together with another section or slotted component using slotted joiners. When cut, this duct type requires the use of a Slotting Tool to add end slots. This style of duct also has openings spaced along the duct for optional bend-radius guides.
Solid ducting has no pre-cut slots or openings and uses slotless joiners which employ a clamping mechanism to securely join components. A standard (flat- blade) screwdriver is used to engage the clamping mechanism
Joiners, slotted or slotless, are needed between each duct system component. Slotless joiners are compatible with both duct types.
Elbows, Tees, Crosses, and Reducers
In addition to straight duct sections, a variety of horizontal and vertical transition components are available. Transitions provide flexibility in design allowing the FRS to be designed around any structural impediments while supporting any Rack or Cabinet layout.
Horizontal elbows add 30, 45, or 90-degree horizontal bends to the pathway layout without changing ducting elevation.
Horizontal tees provide a three-way intersection point allowing cabling to route to multiple locations.
Horizontal crosses provide a four-way intersection point.
Vertical elbows provide 30, 45, or 90-degree bends along the vertical axis providing a method to transition to duct sections mounted at different elevations or to implement large-volume cable drop-offs.
Vertical tees provide a method to continue the horizontal section while
allowing a large volume of cable to drop off vertically to duct sections
mounted at different elevations or to rack or cabinet infrastructure.
Reducers ( not pictured) provide a means to transition duct size from larger to smaller. As cabling is routed to its destination the capacity requirements may reduce and a smaller duct size may be better suited to accommodate the required volume of cable.
Drop-offs, Tubing, Bend Radius Guides, & End Caps
Drop-offs, tubing, and bend radius guides are available to provide easy handoff of cabling from the FRS to Racks or Cabinets. These smaller volume transitions can be added anywhere within the system where needed. End caps close off duct section ends but may be provisioned with knockouts for small- volume exits from the FRS.
Side Drop-off Kits provide the ability to add horizontal to vertical
transitions at any point along a duct section. Drop-offs are available in cut-
in or ramp-over styles in 2×2 and 4×4 duct outlet sizes. Tubing drop-offs are
also available supporting round or square convoluted tubing for flexible
transitions.
Bend Radius Guides snap into slotted duct slot openings and provide bend- radius compliant exits for patch-cords and small OD cables.
Tubing Sections provide flexible transitions from the raceway systems to the building structure and are available in square or round configurations.
End Caps are available to finish pathways and can be solid or provided
with knockouts to allow transition into or out of the raceway system.
Fiber storage loops
Storage-loop sections are available in inline and offset configurations to
provide storage capacity for excess patch-cord length. Inline storage sections
are installed as a connector between two duct sections. Offset storage
sections serve as an end point for a duct section with fiber exiting the
section in the direction it entered.
Mounting Solutions
Leviton offers flexible solutions to support mounting FRS components to walls,
ceiling structure, ladder-rack, Unistrut, under floor and above cabinet
applications. Support requires two components: the support bracket(s) and the
Duct-mounting bracket. Verify kit contents when ordering, not all kits include
the duct mounting bracket.
Wall Mounting Kits
