OEM and customized MTP/MPO trunk cable assemblies are available for data center and structured cabling projects. Cable length, fiber count, fiber type, connector configuration, connector polish, polarity, jacket construction, labeling, and packaging can be customized according to project requirements.

Alternative MTP/MPO connector configurations and fiber counts can also be supplied for specific network architectures. Custom cable constructions can be developed for different installation environments, equipment interfaces, and high-density distribution requirements.

What does MTP-12 (x12) mean in this 144-fiber cable?

The designation means that each end contains twelve MTP/MPO connectors, with each connector carrying 12 fibers. Twelve 12-fiber connectors provide a total of 144 optical fibers, making the assembly a Base-12 high-density trunk configuration.

What is the purpose of Type C polarity in this assembly?

Type C polarity reverses the fiber pairs between the two ends of the cable. This is different from Type A, which maintains the same fiber position, and Type B, which reverses the complete fiber sequence. Type C is used where pair-level reversal is required by the specific duplex or parallel-optics link architecture.

Why is OM4 preferred for high-density data center cabling?

OM4 is a laser-optimized multimode fiber with higher bandwidth capability than earlier multimode grades such as OM3. It is well suited to short-reach, high-speed data center applications and allows high-bandwidth optical links to be deployed over relatively compact distances using multimode transceivers.

Does the 0.25dB specification apply to every connector?

The original specification states that 97% of channels achieve an insertion loss of ≤0.25dB, while the typical connector insertion loss is below 0.12dB. Therefore, 0.25dB should be treated as the specified performance level for 97% of channels rather than a guaranteed value for every individual channel.

Why is the cable diameter larger than a 48-fiber trunk?

The 144-fiber assembly contains three times as many optical fibers as a 48-fiber trunk, so its overall cable construction naturally requires more internal space. The approximately 17.5 mm diameter provides a practical balance between high fiber capacity, mechanical protection, and cable routing requirements.

Can this cable be used with MTP/MPO cassettes from other manufacturers?

Yes, the MTP/MPO interface is based on standardized multi-fiber connector technology and can be used with compatible cassettes and adapter modules from other manufacturers. However, connector performance, polarity, gender, and key orientation should be verified before deployment to ensure compatibility with the complete link.
