MTP Fiber Cables

MTP® jumpers enable smooth upgrades to higher data rates in data centers when paired with our trunk assemblies. They are commonly utilized for interconnections within racks. MTP® cable provides a cost-efficient substitute to labor-intensive on-site termination and is built for compact, high-density fiber connectivity in environments requiring space efficiency and simplified cable routing.

MTP®-16 is perfectly suited for 16-fiber parallel single-mode transceiver solutions, including 800G QSFP-DD/OSFP DR8 and 800G OSFP XDR8 module links.

Note: US Conec’s MTP® connectors fully adhere to MPO standards, featuring patented innovations, improved alignment precision, verified dependability, and enhanced performance over standard MPO types.

MTP Jumper Cable Polarity

MTP®-16 Type A is a 16-fiber cable assembly that uses straight-through polarity. In this configuration, each fiber position at one connector end is aligned to the same numbered position at the opposite end (fiber 1 to fiber 1, fiber 2 to fiber 2, …, fiber 16 to fiber 16). The connectors are oriented in a key-up to key-down position, meaning the fiber sequence is maintained from end to end without reversal.
This polarity type is the most straightforward and is commonly used in parallel optics and structured cabling where direct one-to-one mapping is required.

MTP Fiber Cables 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 single-mode 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 Cables Test Series

MTP Fiber Cables 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 Cables 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 Cables 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. ‌ ‌
