Data Center Migration and the Role of MPO Cables
In modern enterprise data centers, optical fiber networks are becoming increasingly prevalent. One of the popular choices for high-speed network cabling is parallel fiber connections based on the MPO (Multi-fiber Push On) system. This system offers several advantages, including fast pre-termination cabling applications, scalability, and reduced errors. The evolution towards AI hyperscale data centers further underscores the importance of efficient and scalable cabling solutions.
Multimode Optical Fiber Cabling
One of the challenges of migrating to higher speed networks is the lack of space. To meet the high-density fiber requirements, network designers are increasingly turning to MPO connectors. An MPO connector can replace an LC duplex port, supporting up to 12 times more network connections. MPO connectors come in various versions, including 8, 12, and 24 fiber configurations.
Addressing Space Constraints with MPO Connectors
Multimode fiber continues to be the preferred choice for most enterprise data centers due to its cost-effectiveness compared to singlemode fiber. Recent advancements, such as SWDM4 and the new OM5 fiber type, support longer distance transmissions, further extending the applications of multimode fiber. High-speed network transmission can be achieved using multiple fibers, such as with the 40GBASE-SR4 standard, or by building channels within a single pair of fibers using WDM (Wavelength Division Multiplexing).
Types of MPO Connectors
- MPO 12f Connector: This is the standard MPO port for both singlemode and multimode fibers, with a history of decades of usage in backbone applications. For QSFP (Quad Small Form-factor Pluggable) applications, the central 4 fibers of the MPO 12 connector are left unused to mate with the QSFP’s 8 ports.
- MPO 24f Connector: This connector is the most cost-effective for duplex and parallel optical systems. It provides 24 fibers in a single connector, offering higher density compared to three MPO 8 or two MPO 12 connectors. It also saves time on cleaning and inspection during installation. The MPO 24 system is widely used in parallel applications, such as 100G SR-10, which requires 10 pairs of 10x10G configured multimode fiber, and is often extended to 12x10G switch ports.

Advantages of MPO Connectors
- Quick and Easy Installation: MPO cables are designed to quickly connect multiple fibers, reducing deployment and maintenance time. With pre-terminated fibers and standardized connectors, they are practically plug-and-play.
- Scalability: The modular nature of MPO systems makes it easy to add extra fiber capacity and expand the network architecture for future upgrades.
- Reduced Errors: Pre-terminated MPO cables minimize the need for field termination operations, decreasing the likelihood of connectivity errors and reducing losses caused by plugging and unplugging.
- Reduced Cabling: MPO cables occupy less physical space, allowing for more efficient airflow around the data center.
- Higher Transmission Rates: MPO connectors support parallel optics applications, enabling the transmission and reception of signals over multiple fibers to achieve higher speeds.
- Cost Effective: MPO connectors can be more cost-effective than individual connectorized cable assemblies.
