ℹ️
MPO (Multi-fiber Push On) is a type of optical connector that has been the primary multiple fiber connector for high-speed telecom and data communications networks. It has been standardized within the IEC 61754-7 and TIA 604-5.
This connector and cabling system first supported telecommunications systems especially in the Central and Branch offices. Later it became the primary connectivity used in HPC or high-performance computing labs and enterprise datacenters. MPO connectors increase your data capacity with a highly efficient use of space.
💡
While MPO connectors offer benefits over typical single fiber connectors, they introduce new challenges for testing and troubleshooting. Understanding these essentials is critical for technicians working with multi-fiber networks.
The MPO connector family has evolved to support a wider range of applications. Originally a single row 12-fiber connector, there are now 8 and 16 single row fiber types that can be stacked to form 24, 36, and 72 fiber connectors using multiple precision ferrules. The MPO connector is available in both Male (with pins) and Female (without pins) types.
MTP/MPO harness cables (breakout or fan-out cables) are terminated with MTP/MPO connectors on one end and standard connectors like LC, FC, SC, ST, or MTRJ on the other. Typically, these use 3.0mm LSZH round main cables and 2.0mm breakout cables.

Single Mode Fiber: Features a small diametral core allowing only one mode of light to propagate. This reduces light reflections and attenuation, enabling signals to travel further. It is ideal for long-distance, high-bandwidth applications.

Frequently Asked Questions
What are the standards for MPO connectors?
MPO connectors are standardized according to international specifications IEC 61754-7 and TIA 604-5 (FOCIS-5).
What is the difference between Male and Female MPO connectors?
The primary difference is the presence of alignment pins. Male connectors have two precision pins, while Female connectors have holes to accept those pins for proper alignment.
What fiber counts are available for MTP/MPO patch cables?
Cables are available in various configurations including 8, 12, 16, 24, and 48 cores, supporting a wide range of high-density applications.
What is an MPO harness cable used for?
Harness cables provide a transition from multi-fiber cables to individual fibers or duplex connectors (like LC or SC), facilitating high-performance and speedy installation in high-density environments.
What are "Elite" type MPO connectors?
Elite or Low Loss connectors offer superior performance with a maximum insertion loss of ≤ 0.35 dB, compared to ≤ 0.75 dB for standard types.
Are these cables compliant with LSZH requirements?
Yes, the main cables are typically 3.0mm LSZH (Low Smoke Zero Halogen) round cables, suitable for safety-conscious environments.
