Consolidate High Fiber Counts
Use a single multi-fiber trunk assembly instead of routing many individual patch cords through backbone pathways.
STAR400 MTP trunk cables
Pre-terminated, bend-insensitive multi-fiber trunk assemblies with MTP® connectivity, low-loss optical performance and integrated installation hardware for scalable data center backbone cabling.
Backbone links between data center zones can carry large fiber counts through limited pathways. STAR400 MTP® Trunk Cables combine multiple fiber groups into a pre-terminated assembly, reducing the number of individual cables that must be routed and terminated in the field.
The source positions the family for data centers, high-density environments, storage area networks, communications rooms and data communication networks. Strain-relief hardware and pull-eye installation aids support safer routing and faster mounting into STAR400 products.
Deploy Pre-Terminated Links Faster
Factory-installed MTP® connectors, fanouts and pull-eye hardware reduce field termination and simplify cable pulling.
Protect Optical Performance
Every fiber is supported by IL/RL testing and ferrule-geometry interferometer verification before deployment.
Mount Directly into STAR400 Infrastructure
Integrated strain-relief grips are designed for quick cable mounting onto STAR400 products.

The Build Your Order matrix supports an MTP® connector on Side 1 and multiple Side-2 termination choices, allowing the trunk family to support MTP-to-MTP as well as pre-terminated breakout-style assemblies.
Capacity QA: the datasheet states capacity up to 144 fibers, while the Base-8 ordering matrix stops at 12×8 fibers (96 fibers), matching the current website. Confirm the commercial range before publishing a single maximum-fiber claim.

Return Loss QA hold: the source prints “>-35 dB” and “>-60 dB (8° Angle Polish)”. Those values are intentionally withheld from this public table until Engineering confirms the intended notation.
| No. of Fibers | Outer Diameter | Max. Bend Radius – Installation | Max. Bend Radius – Operation |
|---|---|---|---|
| 8 | 4.3 mm | 60 mm | 30 mm |
| 16 | 5.2 mm | 108 mm | 54 mm |
| 24 | 7 mm | 122 mm | 61 mm |
| 32 | 7 mm | 122 mm | 61 mm |
| 48 | 8.7 mm | 188 mm | 94 mm |
| 64 | 9.4 mm | 200 mm | 100 mm |
| 96 | 10.8 mm | 222 mm | 111 mm |
| 144 | 13.5 mm | 270 mm | 135 mm |
The source labels these columns “MAX. BENDING RADIUS”. The values are reproduced as published; engineering should confirm whether the intended term is maximum or minimum bend radius before the table is used in installation instructions.
The supplied datasheet lists the following verification measurements for STAR400 trunk assemblies:
- Insertion Loss
- Return Loss
- Radius of Curvature
- Tilt
- Fiber Height
Page 3 also shows a ferrule-geometry interferometer result, reinforcing the documented inspection process for connector geometry.
