OS2 MPO Cable Types

The MPO jumper cable provides a reliable and cost-effective replacement for traditional field termination methods. It is specially designed for high-density fiber cabling in data centers, enabling better space utilization and more efficient cable management. In addition, the bend-insensitive fiber design ensures stable and high-speed signal transmission, even in compact routing spaces and tight bend conditions.

MPO Patch Cord Polarity

The MPO 8-fiber Type B male connector is a high-density fiber optic connector designed for high-speed parallel optical transmission in modern data centers. It follows the Type B polarity standard, which uses a reversed fiber mapping configuration. In this setup, the fiber positions are mirrored from one end of the connector to the other to ensure correct transmit (Tx) and receive (Rx) alignment.

For example:

• Fiber 1 → Fiber 12
• Fiber 2 → Fiber 11
• Fiber 3 → Fiber 10
• Fiber 4 → Fiber 9
• …
• Fiber 9 → Fiber 4
• Fiber 10 → Fiber 3
• Fiber 11 → Fiber 2
• Fiber 12 → Fiber 1

As a male connector, it includes two guide pins on the MT ferrule. These pins provide accurate alignment when mating with a female MPO connector, ensuring low insertion loss and stable optical performance.

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.

MPO Cable Tester Series

MPO Patch Cable 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. ‌

MPO Fiber Patch Cords 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.

Fiber Optic MPO Patch 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. ‌ ‌
