MTP Cable

MTP® jumpers provide a smooth upgrade path to higher data rates in data centers when used with our trunk cables. They are commonly applied for patching tasks within equipment cabinets. As a cost-effective alternative to traditional field termination, MTP® cables are optimized for high-density fiber deployments where space savings and simplified cable management are important.

Because MTP®-12 connectors also support MTP®-8 fiber configurations, they are well-suited for 8-fiber parallel single-mode transceiver applications, such as 40G QSFP+ PLR4, 100G QSFP28 PSM4, 400G OSFP DR4/XDR4, and 400G QSFP-DD DR4/XDR4 optical links.

Please note: US Conec’s MTP® connectors are fully compliant with MPO standards and deliver patented mechanical designs, excellent precision, reliable performance, and measurable advantages over standard MPO connectors in demanding environments.

MTP Patch Cable Polarity

The MTP® 12-fiber Type B male connector is a high-density fiber optic interconnect solution widely used in data center cabling systems. Type B polarity follows a reversed (flipped) fiber mapping, meaning that the fiber positions at one connector end are mirrored at the opposite end. For example: Fiber 1 → Fiber 12, Fiber 2 → Fiber 11, Fiber 3 → Fiber 10 … Fiber 12 → Fiber 1. This configuration ensures that transmit (Tx) fibers on one device are properly aligned with receive (Rx) fibers on the other device.
As a male connector, it is manufactured with two alignment pins on the ferrule, which guarantee precise mating with female connectors, maintaining low insertion loss and consistent optical performance.

mtp 12 jumper Key Features:

Connector type: MTP® 12-fiber male (with guide pins)
Fiber count: 12 fibers in a single-row high-density ferrule
Polarity standard: Type B (reversed polarity) for proper Tx/Rx alignment
Cable jacket options: OFNR, OFNP, LSZH, with standard color codes (yellow for OS2, aqua/violet for OM3/OM4, lime green for OM5)
Enhanced design: MTP® technology provides better mechanical durability, higher return loss, and lower insertion loss compared to standard MPO connectors

mtp 12 jumper Applications:

Parallel optics systems: Supports 40GBASE-SR4 and 100GBASE-SR4 Ethernet using 8 fibers (4 Tx + 4 Rx), with the remaining fibers reserved or unused depending on the design
Direct equipment connections: Often used for linking MPO/MTP® transceivers that require flipped polarity
Backbone cabling: Connects MTP® trunks, cassettes, and patch panels in modular data center infrastructure
Migration-ready systems: Provides flexible scalability from 10G duplex channels to 40G and 100G parallel optics

mtp 12 jumper Advantages:

Ensures proper Tx/Rx orientation: Reversed fiber mapping aligns transmitters with receivers
High-density design: 12 fibers in one connector reduce cabling volume in high-density racks

MTP 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 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 Cable Test Series

MTP 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 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 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. ‌ ‌
