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

The MTP® 16-fiber Type B male connector is a high-density optical interconnect solution optimized for parallel optics in advanced data centers. Type B polarity follows a reversed (flipped) mapping, which means the fiber positions at one end of the connector are mirrored at the opposite end. For example: Fiber 1 → Fiber 16, Fiber 2 → Fiber 15, Fiber 3 → Fiber 14 … Fiber 16 → Fiber 1. This ensures that transmit (Tx) fibers on one device connect directly to receive (Rx) fibers on the opposite device, which is essential for parallel transmission protocols.
As a male connector, it is equipped with two alignment pins on the ferrule, ensuring precise core-to-core alignment when mated with female connectors. This guarantees stable optical performance with low insertion loss.

MTP Jumper Cable Key Features:

Connector type: MTP® 16-fiber male (with guide pins)
Fiber count: 16 fibers in a single-row high-density ferrule
Polarity standard: Type B (reversed mapping, flipped orientation)
Cable jacket options: OFNR, OFNP, or LSZH, with standard color codes (yellow for OS2, aqua/violet for OM3/OM4, lime green for OM5)
Enhanced design: MTP® technology improves return loss, minimizes insertion loss, and ensures robust durability compared to generic MPO connectors

MTP Jumper Cable Applications:

High-speed parallel optics: Supports 200GBASE-DR4, 400GBASE-SR16, 400GBASE-DR4, and emerging high-bandwidth Ethernet standards
Direct transceiver connections: Commonly used for 16-fiber transceivers, where reversed polarity is necessary for correct Tx/Rx alignment
Data center backbone cabling: Enables structured cabling systems with modular trunks and cassettes

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. ‌ ‌
