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

The MTP® 8-fiber Type C male connector is a compact, high-density fiber optic solution designed for structured cabling in data centers. It adopts the pairwise flip polarity method, where fibers are crossed in pairs to ensure proper transmit (Tx) and receive (Rx) alignment. Specifically, Fiber 1 connects to Fiber 2 at the far end, Fiber 3 connects to Fiber 4, Fiber 5 connects to Fiber 6, and Fiber 7 connects to Fiber 8.
As a male connector, it includes two alignment pins on the ferrule, which ensure precise core-to-core alignment when mating with female connectors, minimizing insertion loss and guaranteeing stable performance.

MTP Jumper Cable Key Features:

Connector type: MTP® 8-fiber male (with guide pins)
Fiber count: 8 fibers in a single-row ferrule
Polarity method: Type C (pairwise flip) – fibers are crossed in adjacent pairs for correct Tx/Rx alignment
Cable jacket options: OFNR, OFNP, or LSZH, with industry-standard colors (yellow for OS2, aqua/violet for OM3/OM4, lime green for OM5)
Enhanced design: MTP® connectors provide superior mechanical durability and lower optical loss compared to standard MPO

MTP Jumper Cable Applications:

Parallel optics transmission: Suitable for 40GBASE-SR4 and 100GBASE-SR4 Ethernet, where correct Tx/Rx mapping is required
Data center backbone cabling: Connects MTP® trunk cables, cassettes, or panels with pairwise polarity requirements
Migration-ready cabling systems: Supports smooth transition from lower-speed duplex links to parallel 40G/100G solutions
Breakout configurations: Works with MTP®-to-LC harness cables for connecting 8-fiber transceivers to multiple duplex ports

MTP Jumper Cable Advantages:

Correct Tx/Rx mapping: Pairwise flip design prevents channel inversion errors
Compact and efficient: 8 fibers in one connector reduce cabling bulk in high-density racks
Reliable alignment: Male guide pins guarantee stable and precise mating with female connectors
Scalability: Supports modular cabling systems designed for future bandwidth upgrades

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. ‌ ‌
