FAQ
The 48-Fiber OM3 MTP/MPO Trunk Cable is a high-density multimode backbone assembly designed for data centers, structured fiber cabling systems, and high-speed short-reach network connections. It uses four 12-fiber MTP/MPO connectors at each end, providing 48 optical fibers in a compact micro-core cable construction. The assembly uses OM3 50/125μm multimode fiber and MTP® Elite® UPC connectors to provide reliable optical connectivity while helping reduce cable congestion and improve the use of rack and pathway space.
Configured with Type C polarity, the cable reverses fiber pairs between the two ends and can be integrated into compatible MTP/MPO structured cabling architectures. Its factory-terminated construction enables fast deployment without field connector termination, making it suitable for connections between MTP/MPO cassettes, adapter modules, fiber distribution systems, and high-density network equipment.| Total Fiber Count | 48 Fibers |

OEM and customized MTP/MPO trunk cable assemblies are available for different network architectures and installation requirements. Cable length, fiber count, fiber type, connector configuration, connector polish, polarity, jacket construction, labeling, and packaging can be customized according to project specifications.
What does Type C polarity mean in this 48-fiber trunk cable?
Type C polarity reverses the fiber pairs between the two connector ends. For a 12-fiber MTP/MPO connection, the fibers are mapped as pairs rather than simply maintaining or completely reversing the fiber sequence. This configuration is useful in specific duplex parallel-optics architectures where pair reversal is required.
Why is OM3 50/125μm fiber suitable for this trunk cable?
OM3 is a laser-optimized multimode fiber designed for high-speed short-distance transmission, particularly in data center and enterprise environments. Its 50/125μm construction provides the bandwidth characteristics required by many multimode Ethernet applications while supporting compact, high-density cabling architectures.
What does “MTP-12 (x4)” mean?
It means that each end of the trunk cable contains four MTP/MPO connectors, with each connector carrying 12 fibers. Four 12-fiber connectors provide a total of 48 optical fibers at each end of the assembly.
Can this cable be connected to standard MPO cassettes?
Yes, the MTP/MPO interface follows the standardized multi-fiber connector format and can be used with compatible MTP/MPO cassettes and adapter modules. However, connector performance can vary between components, so the complete link should be evaluated based on the optical loss budget and mating component specifications.
Why use a micro-core trunk cable for high-density installations?
A micro-core construction allows many fibers to be consolidated into a relatively compact cable. This can reduce pathway congestion and make cable routing and management easier, particularly in data center racks where space, airflow, and bend management are important considerations.
Can the connector configuration be changed from UPC to APC?
Yes, customized connector configurations can be considered depending on the application. However, APC and UPC connectors have different end-face geometries and should not be intermated directly. The connector polish should therefore be selected according to the requirements of the mating equipment and complete optical link.
