MTP Fiber Optics

MTP® jumpers ensure smooth migration to higher data rates in data centers when used with our trunk cables. They are typically installed for patching connections within cabinets. MTP® cables offer a cost-efficient replacement for traditional field termination, specifically designed for high-density fiber deployments that demand space conservation and simplified cable routing.

Because MTP®-12 connectors also support MTP®-8 fiber layouts, they are well-suited for 8-fiber multimode optical transceivers, including 40G QSFP+ SR4/CSR4 and 100G QSFP28 SR4 optical modules.

Please note: US Conec’s MTP® connectors fully comply with MPO standards and deliver innovative patented features, high alignment accuracy, proven stability, and superior optical performance when compared to standard MPO connectors used in similar applications.

MTP Patch Cable Polarity

The MTP® 12-fiber Type A male connector is a high-density optical interconnect commonly used in structured cabling systems within data centers. Type A polarity follows a straight-through fiber mapping, meaning that each fiber at one end of the connector aligns directly with the same position at the opposite end. For example: Fiber 1 → Fiber 1, Fiber 2 → Fiber 2 … Fiber 12 → Fiber 12.
As a male connector, it is equipped with two alignment pins on the ferrule, ensuring precise core alignment when mated with female connectors. This design minimizes insertion loss and guarantees reliable optical performance.

MTP Fiber Optics SPIN-LEAF connection method

MTP Fiber Optics 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 Fiber Optics Test Series

MTP Fiber Optics 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 Fiber Optics 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 Fiber Optics 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. ‌ ‌
