Fiber optic trunk cable BlueOptics MPO/UPC to MPO/UPC 3 m OM4 12-core LSZH Type B

BlueOptics fiber optic trunk cable MPO/UPC to MPO/UPC 3 m OM4 12-core LSZH Type B is a pre-terminated multimode cable designed for high-density network environments. It features MPO/UPC connectors on both ends and 12 optical cores arranged for Type B polarity, using OM4 multimode fiber to support high-speed short-reach links. The cable jacket is low-smoke zero-halogen (LSZH), providing reduced toxic emission in confined spaces. At 3 meters length, this trunk cable is intended for interconnects, patching and spine-leaf connections where compact MPO connectivity and OM4 performance are required.

Advantages

The BlueOptics trunk cable offers a compact MPO/UPC interface that simplifies installation in racks and panels while maintaining consistent multimode OM4 performance. Type B polarity ensures compatibility with systems and breakout assemblies that require a flipped fiber mapping, and the 12-core design supports parallel optics applications or multiple duplex channels within a single connector pair. The LSZH jacket reduces smoke and halogen release in case of fire, which is suitable for data center and indoor installations where safety standards prioritize low-toxicity materials.

Suitable for

• High-density data center trunking and interconnects
• Spine-leaf links and short-reach parallel optics
• Patch panel to cassette connections using MPO interfaces
• Environments requiring OM4 multimode performance for 10/40/100 Gbps short links

When it may not be suitable

This trunk cable is multimode OM4 and optimized for short-reach connections; it is not appropriate for long-haul singlemode applications or links that exceed multimode distance limitations. It also uses Type B polarity mapping, which may not match systems that require Type A or Type C polarity without additional adapters or reconfiguration.

Key specifications

• Fiber type: OM4 multimode fiber
• Connector type: MPO/UPC to MPO/UPC, both ends
• Number of cores: 12 optical fibers
• Polarity: Type B
• Length: 3 m
• Jacket material: Low-Smoke Zero-Halogen (LSZH)
• Application: Trunk cable for high-density patching and parallel optics

How to use

Install the BlueOptics MPO/UPC to MPO/UPC trunk cable by inserting the MPO connectors into compatible MPO ports or MPO cassettes on patch panels and transceivers. Ensure the Type B polarity mapping matches the connected equipment or patching scheme before deployment. Secure the cable along routing paths using appropriate management hardware to avoid sharp bends and stress on the connectors. Verify optical continuity and insertion loss with appropriate test equipment after installation to confirm expected OM4 performance.

What to consider before purchase

• Confirm that OM4 multimode fiber and MPO/UPC connectors meet the performance requirements of your transceivers and patching system.
• Verify that Type B polarity is compatible with your network design or that required adapters/patching are available.
• Ensure 3 m length is appropriate for the intended routing and does not introduce excess slack or tension.
• Check that LSZH jacket material meets the safety requirements for your installation environment.

Usage recommendations

Maintain minimum bend radius guidelines for OM4 multimode fiber and avoid repeated mating cycles beyond connector specifications. Use the cable in conjunction with MPO-compatible cassettes or patch panels for organized high-density installations, and perform insertion loss testing after installation to document link performance.
