Panduit FTR2X2LBL FiberRunner 2x2 Trumpet

The Panduit FTR2X2LBL trumpet is a flared transition fitting designed for 2x2 FiberRunner cable routing systems in data centers and telco central offices. Trumpets provide the gradual bend-radius expansion needed when fiber bundles exit horizontal runway and drop vertically to equipment racks or cross-connect fields. Without proper flaring, tight 90-degree transitions crush fiber jackets and violate minimum bend-radius specs—risking attenuation spikes and long-term failure. This trumpet maintains ANSI/TIA-568 and manufacturer bend-radius requirements while keeping cable bundles organized during the transition from overhead pathway to vertical distribution.

Key Features

• Flared trumpet design for 2x2 FiberRunner systems—maintains minimum bend radius during horizontal-to-vertical transitions
• Black polycarbonate/ABS blend construction—impact-resistant, flame-retardant, and dimensionally stable across -40°F to 150°F operating range
• 3.85" height × 6" width opening—sized for high-density fiber bundles in 2x2 runway without compression
• UL 2024 Listed for Optical Fiber Cable Routing Assemblies—meets Telcordia GR-63-CORE Level 3 seismic and environmental requirements
• RoHS compliant—lead-free and safe for installation in occupied telecom spaces and LEED-certified facilities
• Five-pack carton—sufficient hardware for typical row deployment or cross-connect field perimeter

The FTR2X2LBL trumpet installs at the terminus of 2x2 FiberRunner horizontal runway where cable bundles transition downward to equipment. The 3.85-inch flare depth provides gradual radius expansion—critical for OM3/OM4/OM5 multimode and OS2 singlemode fiber, which require minimum 10× cable-diameter bend radius under load. The 6-inch-wide opening accommodates up to 144-count trunk cables or multiple 12-fiber distribution cables exiting a single runway section. Polycarbonate/ABS blend construction resists impact from installation activity and provides long-term dimensional stability—no sagging or deformation under bundle weight in hot aisle environments. Black finish matches standard FiberRunner runway and bracket components for consistent data center aesthetics.

Installation integrates with Panduit's snap-together FiberRunner system—no fasteners required for trumpet attachment to 2x2 runway sections. The trumpet mounts at runway end-points, typically at row-end transitions where horizontal pathways drop to vertical cable managers or at perimeter walls where fiber enters/exits the data center floor. In telco central offices, trumpets are deployed at MPOE (Minimum Point of Entry) terminations and at cross-connect field boundaries where outside plant fiber transitions to intra-office distribution. The flared geometry also functions as a cable retention feature—bundles naturally rest in the trumpet throat during dressing, reducing strain on downstream terminations.

This component meets UL 2024 optical fiber cable routing assembly standards and Telcordia GR-63-CORE Level 3 requirements—covering flammability (UL 94 V-0 equivalent), seismic performance (Zone 4 earthquake simulation), and temperature cycling (-40°C to +65°C). Compliance ensures the trumpet is approved for above-ceiling plenum pathway installations and for carrier-grade telecom facilities where NEBS (Network Equipment-Building System) certification is mandatory. Five-unit packaging aligns with typical FiberRunner projects—a standard data center row with 10-12 racks typically requires 4-6 trumpets depending on pathway layout and whether fiber feeds from overhead or underfloor distribution.
