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 Jumper Cable Polarity

MTP®-8 Type C is an 8-fiber cable assembly that uses a pairwise flipped polarity design. In this configuration, the fibers are reversed in adjacent pairs, which automatically swaps the transmit (TX) and receive (RX) positions between the two ends. This ensures correct channel alignment without requiring additional cross-over patch cords.
The connector orientation is usually key-up to key-down, but unlike Type A (straight-through), the internal fiber mapping rearranges each duplex pair.

MTP Jumper Cable Key Features:

Fiber Count: 8 fibers in a single row.
Polarity: Type C — Pairwise flipped mapping
Connector: MTP® 8F (male or female) compliant with IEC-61754-7 and TIA-604-5 (FOCIS-5)
Application: Ideal for structured cabling with MTP®-LC cassettes, converting parallel to duplex links for transceivers such as 40G SR4, 100G SR4, and 400G SR4.2
Benefit: Maintains correct TX/RX without extra cross-over cords, reducing errors in polarity management

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. ‌ ‌
