Product introduction

The Fiber Cable Tray End Cup is a key accessory in the fiber optic trough system. It is made of flame-retardant ABS material to ensure safety and stability. This port baffle is exquisitely designed to perfectly close the end of the fiber optic trough, effectively prevent dust and debris from entering, and protect the optical fiber from accidental damage. Its flame retardant performance meets the UL94 FV-0 standard and is safe and reliable. The port baffle is easy to install and has strong compatibility. It is suitable for various fiber optic trough systems. Its smooth surface and neat appearance not only improve the overall aesthetics, but also effectively guide the optical fiber line to ensure smooth and efficient data transmission. Whether it is a new or expanded data center, the port baffle is an indispensable and high-quality choice.

Fiber Cable Tray End Cup

Product classification: Optic Cable Tray

Product Overview

The fiber cable tray end cup is a termination accessory installed at the open ends of optic cable trays. It creates a封闭 barrier that prevents debris accumulation, physical contact with cable terminations, and accidental displacement of fiber optic cables. Manufactured from steel with electrostatic powder coating, the end cup matches standard tray dimensions (widths from 100mm to 600mm). The component features pre-drilled mounting holes aligned with tray rungs and a smooth rounded edge profile that eliminates sharp corners. When installed, the end cup maintains bending radius compliance for optical fibers exiting or terminating at tray endpoints. Its design integrates with straight sections, vertical bends, or horizontal elbows to provide consistent cable protection across the entire cable management pathway.

Core Advantages

Dimensional compatibility with standard optic cable tray widths (100mm, 150mm, 200mm, 300mm, 400mm, 500mm, 600mm).
0.8mm to 1.5mm thickness galvanized steel substrate with corrosion-resistant polyester coating (80-100 microns).
Tool-free snap-fit installation on trays with slotted rungs; screw fixing available for high-vibration environments.
Rounded edges with 5mm radius to prevent fiber bending radius violations (meets IEC 60794-1-21).
Open slot design at bottom for cable drainage and ventilation, reducing moisture retention.

Product Characteristics

Surface finish	Electrostatic powder coating, RAL 7035 or RAL 9010; thickness 60-80μm
Thickness options	1.0mm, 1.2mm, 1.5mm (depending on tray load rating)
Width compatibility	100mm to 600mm, adjustable via side flanges
Height	50mm, 80mm, 100mm, 120mm (matches tray side rail height)
Temperature range	-40°C to +85°C
Fire rating	UL 94 V-0; oxygen index ≥28% (plastic components absent in all-steel version)
Installation method	Screw fixing (M6x12 bolts) or clip-on with spring nuts

Application Scenarios

Data center cable trays at endpoints where fiber jumpers transition to equipment racks.

Telecom central offices and headends requiring termination protection for backbone optical cables.

Industrial automation environments with vibration, preventing cable end displacement.

Cable riser shafts and building distribution points where trays end at wall penetrations.

Outdoor fiber enclosures and cabinet entry points (IP30 rating with gland plate optional).

Technical Notes & Solutions

Installation clearance requirement

Maintain minimum 25mm space between end cup and adjacent walls or equipment. Restricted clearance may cause fiber bend radius below 40mm for standard SMF-28 fibers. Use offset end cups (angled 15 or 30 degrees) when space is constrained.

Grounding continuity

End cups with painted surfaces do not automatically bond to tray grounding. Install grounding clips or star washers between mounting screws and tray to ensure electrical continuity for system grounding per TIA-607-B.

Moisture management in outdoor trays

For outdoor or wash-down areas, select end cups with bottom weep holes (2mm diameter, spaced 50mm). Without drainage, condensation accumulates and increases insertion loss in optical connectors. Slotted end cups provide ventilation and reduce differential pressure.

Compatibility with cable ladder vs. perforated tray

Standard end cups are designed for perforated cable trays. For ladder-type trays (rungs spaced at 250mm or 300mm), use extended flange end cups that overlap beyond the last rung to prevent cable sagging at the endpoint.

Frequently Asked Questions

Can the end cup be retrofitted on existing installed trays?

Yes. The end cup slides over the tray side rails without removing cables. However, if cables extend beyond the tray end by more than 30mm, temporary support is required during installation to prevent fiber strain.

What is the load capacity of the end cup itself?

The end cup is not designed for load-bearing. Maximum axial force 50N (equivalent to 5kg static) applied to the end face. For cable pulling or tension applications, use dedicated pull-off elbows or termination boxes.

Does the end cup require gaskets for dust protection?

Standard version has no gasket. For IP4X protection level, order end cups with neoprene gasket (2mm thickness) pre-attached to the flange. Gasket compresses to seal gaps between end cup and tray side rail.

How to identify correct end cup size for existing tray?

Measure internal width between tray side rails (not nominal width). Also measure side rail height. End cup marking indicates compatible tray series, e.g., "C100H80" fits 100mm width x 80mm height tray.
