MTP/MPO Fiber Cable

MTP® jumpers enable smooth migration to higher network speeds in data centers when used together with our trunk cables. They are most commonly used for patching inside cabinets. MTP® cables, offering a cost-effective alternative to time-consuming field terminations, are designed for high-density fiber deployments in data centers that require space efficiency and simplified cable organization.

MTP®-8 is perfectly suited for 8-fiber parallel multimode optical transceiver applications, including 40G QSFP+ SR4/CSR4 and 100G QSFP28 SR4 connections.

Please note: US Conec’s MTP® connectors are fully compliant with MPO standards and feature patented innovations, superior precision, excellent durability, and significantly improved performance compared to standard MPO connector solutions.

MTP/MPO Fiber Cable SPIN-LEAF connection method

MTP/MPO Fiber 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.

MTP/MPO Fiber Cable Test Series

MTP/MPO Fiber 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. ‌

MTP/MPO Fiber Cable 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.

MTP/MPO Fiber Cable 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. ‌ ‌
