MPO to MPO Female OM4 3.0mm LSZH 12F MPO Trunk Cable

Product Overview

The 12-Fiber MPO Female to Female OM4 Trunk Cable is a high-speed multimode assembly designed for 40G (40GBASE-SR4) and 100G (100GBASE-SR4) data center applications. This specific configuration features Female (Unpinned) connectors on both ends, making it the ideal solution for direct transceiver-to-transceiver connections (QSFP+ to QSFP+) or for connecting two pinned (Male) trunk cables/panels.

Engineered by MeFiber, this trunk cable utilizes premium laser-optimized OM4 fiber to ensure signal integrity over longer distances compared to OM3. The cable is protected by a robust 3.0mm round LSZH (Low Smoke Zero Halogen) jacket, offering superior durability and easier cable management in high-density racks compared to fragile flat ribbon cables. It is the preferred choice for structured cabling environments requiring safety, durability, and high bandwidth.

Key Features

• OM4 Multimode Performance: Supports 40G Ethernet up to 150m and 100G Ethernet up to 100m, ensuring future-proof bandwidth.
• Female-to-Female Interface: Unpinned connectors on both ends, designed for connecting directly to pinned transceivers or coupling with pinned MPO trunks.
• Rugged 3.0mm Construction: The double-jacketed 3.0mm round design provides extra protection against crushing and bending compared to standard ribbon cables.
• LSZH Jacket: Low Smoke Zero Halogen material ensures safety in confined spaces by minimizing toxic smoke in the event of a fire.
• Precision MPO Connectors: Low insertion loss ferrule technology guarantees stable optical transmission.
• MeFiber Quality: 100% factory tested for geometry, end-face cleanliness, and insertion/return loss.

Applications

This specific MPO trunk configuration is versatile for several critical network scenarios:

• Direct Equipment Connection: Linking two switches directly using QSFP+ or QSFP28 transceivers (which typically have pinned interfaces).
• Trunk Extension: extending an existing Male-to-Male trunk cable.
• High-Density Patching: Connecting pinned cassette modules in Main Distribution Areas (MDA).
• Data Center Interconnects: Reliable cabling for storage area networks (SAN) and server clusters.

Specifications

Why Choose 3.0mm Round Cable?

Standard MPO patch cords often use a flat ribbon cable structure. While compact, ribbon cables can be susceptible to kinking and are harder to route through complex cable managers. The MeFiber 3.0mm round construction encases the fibers in a sturdier, round jacket with aramid yarn reinforcement. This makes the cable more resilient to pulling tension and easier to route around corners in server racks without risking micro-bends.

FAQ

1. What is the difference between MPO and MTP®?

MPO (Multi-Fiber Push On) is the generic connector standard defined by the IEC. MTP® is a high-performance, trademarked brand of MPO connector manufactured by US Conec. MTP® connectors feature specific design improvements, such as a floating ferrule and elliptical guide pins, which enhance durability and maintain better physical contact. While this product uses high-quality MPO connectors standard, MTP® connectors are available upon request for critical applications.

2. Why do I need Female connectors?

MPO connectors use a male/female (pinned/unpinned) alignment system. Most optical transceivers (like QSFP modules) have Male (pinned) interfaces. To connect to them, you must use a Female (unpinned) cable to avoid pin damage. This Female-to-Female cable is specifically designed to bridge two such transceivers or to connect to Male infrastructure.

3. Is OM4 backward compatible with OM3?

Yes. OM4 fiber is fully backward compatible with OM3. However, OM4 offers higher bandwidth and longer transmission distances (e.g., 150m for 40G vs 100m for OM3). Using OM4 ensures your infrastructure is ready for higher speeds while still working with existing Multimode equipment.

4. Can I order custom lengths?

Yes. While we list standard lengths, MeFiber can manufacture this 3.0mm OM4 trunk cable to your exact length specifications to ensure a neat installation without excess slack.
