Optimized for AI Clusters & 800G Migration
High-performance computing (HPC) and cloud data centers require optical links with low insertion loss and stable signal integrity.
Dimi's Ultra-Low Loss (ULL) 48-Fiber MPO Trunk Cables are engineered for the tight optical power budgets of high-density GPU clusters and accelerator architectures.
Our MPO trunks assist network deployment by:
- Supporting Multi-Lane Transmission: Built for 40G, 100G, 200G, 400G, and incremental upgrading to 800G Ethernet.
- Controlling Loss: Minimizing cumulative insertion loss across multi-stage patching links.
- Maintaining Signal Quality: Preserving optical power budgets across high-density spine-leaf and leaf-to-server topologies.

High-Density Cabling with Improved Airflow Efficiency
The 48-fiber trunk architecture consolidates multiple duplex channels into a single assembly, reducing cable congestion inside cabinets and overhead trays.
Compared with traditional LC patching, this MPO design provides:
Increases space utilization in high-density racks.
Decreased cable bulk allows unhindered airflow around switches and servers.
Organized routing shortens troubleshooting and expansion cycles.
Rapid deployment via standardized modular patch panels.
Precision Factory Termination & 100% Individual Verification
Individual Verification
To eliminate the performance variability associated with field termination, all Dimi MPO trunk cables are assembled and polished in an ISO 9001-certified facility.
Each cable undergoes complete automated testing before shipment:
- Optical Testing: 100% Insertion Loss (IL) and Return Loss (RL) inspection per fiber channel.
- 3D Geometry Verification: Automated interferometers verify radius of curvature, vertex offset, and fiber undercut/protrusion to ensure proper physical contact.
- End-Face Inspection: Evaluated via automated pass/fail software according to the IEC 61300-3-35 standard.
- Continuity Mapping: Verification of fiber polarity and link mapping across all channels.
Digital Traceability System
Every cable assembly is labeled with a unique serial number and a QR code.Scanning the code or entering the ID on our portal grants direct access to the specific unit's 3D Interferometer Test Report and optical metrics, simplifying inventory and lifecycle tracking.

FAQ
Q: Are your MPO connectors compatible with other compliant brands?
A: Yes. Our MPO assemblies adhere to IEC 61754-7 and TIA-604-5 (FOCIS 5) standards. They are fully intermateable with any industry-standard compliant MPO interface hardware on the market.
Q: How do we verify the correct Polarity and Gender (Male/Female) before production?
A: MPO links require precise structural alignment of gender (pinned vs. unpinned) and polarity (Type A, B, or C).Our application engineering team is available to review your network topologies, transceiver data sheets, and patch layouts to confirm the exact specifications before manufacturing begins.
Q: Does every cable include an individual test report?
A: Yes. Each cable assembly is individually serialized, QR-coded, and 100% verified.Complete test records-covering IL, RL, end-face inspection, and 3D geometric values-can be accessed instantly via our online cloud database or requested in printed format with your shipment.
