MPO OM4 Cable Types

The MPO jumper cable offers an affordable solution compared to the effort-intensive process of field termination. It is optimized for dense fiber patching in data centers, where conserving space and reducing cable complexity are key priorities. In addition, the bend-insensitive fiber technology supports dependable, high-level performance, even when cables are routed through constrained or sharply bent areas.

The MPO 12-fiber Type B male connector is widely used in modern fiber optic networks, providing reliable reversed-polarity connectivity for high-bandwidth applications while maximizing cabling density and system performance.

MPO OM4 Patch Cord Polarity

The MPO 12-fiber Type B male connector is a high-density fiber optic connector designed for high-speed data center and enterprise network applications. It follows the Type B polarity method, which uses a reversed fiber mapping configuration. This polarity ensures proper transmit (Tx) and receive (Rx) alignment in parallel optical transmission systems.

In a Type B configuration, the fiber positions are mirrored from one end of the connector to the other For example:

• Fiber 1 → Fiber 12
• Fiber 2 → Fiber 11
• ……..
• Fiber 11 → Fiber 2
• Fiber 12 → Fiber 1

As a male connector, it is equipped with two guide pins on the MT ferrule. These pins ensure accurate alignment when mated with a female MPO connector, providing low insertion loss and stable optical performance.

OM4 MPO Cable SPIN-LEAF connection method

OM4 MPO Cable Application

High-speed interconnection in data centers

It is used for direct connection of 40G/100G optical modules, supports 400G high-speed transmission, and can improve wiring density and transmission efficiency. For example, 400G QSFP-DD DR4 optical modules can be directly connected through MPO/MTP-8 multimode fiber jumpers. ‌

High-density wiring scenarios

In the backbone wiring of data centers, MTP/MPO trunk fiber jumpers are used in conjunction with adapter modules to achieve interconnection and cross-connection between devices, saving 45% of wiring space. Branch jumpers are used to connect devices with different rates (such as 10G and 40/100G devices). ‌

100G/400G transmission expansion

Supports branch connection of 100G QSFP28 optical modules to 4 25G SFP28 optical modules, or interconnection of 100G CFP optical modules to another CFP. ‌

Fiber-to-Building Applications

It is used for fiber-to-the-building (FTTB) wiring to meet the needs of high-density fiber access.

OM4 MPO Test Series

OM4 MPO MTP Polarity Test Process

‌End face cleaning: Use special equipment to remove end face contaminants to avoid affecting the test accuracy. ‌
Morphology detection: Analyze the end face microstructure through 3D imaging technology to detect surface roughness, scratches and other defects. ‌
Insertion loss test: Measure the contact loss between the fiber end face and the connector ferrule to evaluate the signal transmission quality. ‌
Polarity verification: Confirm the correspondence between the number of fiber cores and the connector guide hole to prevent communication failure caused by wrong connection. ‌

Fibra MPO OM4 Test Key Indicators

Cleaning efficiency: It must reach more than 98% to ensure that there are no residual stains on the end face. ‌
‌Detection accuracy: The resolution of 3D morphology detection must be less than 1.5μ, and the insertion loss error must be controlled within 0.3dB. ‌
Test time: It takes about 10 seconds to detect a single fiber core of a 12-core MPO jumper, and the overall test takes about 2 minutes.

OM4 MPOw Test Common Problems

Pollution sensitivity: Tiny particles on the end face will cause increased loss, and non-contact cleaning methods are required to protect the end face. ‌ ‌
