MTP Jumper Cable

The MTP® 8-Fiber Single Mode Type A patch cable is designed for high-density optical connectivity and optimized for single mode (OS2) fiber transmission. It features a straight-through (key-up to key-down) polarity configuration, where Fiber 1 at one end connects directly to Fiber 1 at the other end, ensuring consistent and predictable routing in point-to-point links.

This cable uses precision-engineered MTP® connectors compliant with IEC-61754-7 and TIA-604-5 (FOCIS-5) standards, ensuring low insertion loss, high return loss, and excellent optical performance. The 8-fiber design aligns perfectly with QSFP+ and QSFP28 transceivers for 100G Ethernet (4×25G) and 200G (8×25G) applications.

MTP Jumper Cable Polarity

The MTP® 8-fiber Type A male connector is a compact, high-performance fiber optic solution designed for parallel optics and backbone cabling in modern data centers. Type A polarity represents a straight-through configuration, where each fiber position on one end of the cable is mapped directly to the same position on the opposite end (Fiber 1 → Fiber 1, Fiber 2 → Fiber 2 … Fiber 8 → Fiber 8).
As a male connector, it is equipped with two alignment pins on the ferrule to ensure precise mating with female MTP® connectors, guaranteeing stable optical alignment and low insertion loss.

MTP Jumper Cable Key Features:

Connector type: MTP® 8-fiber male (with guide pins)
Fiber Count: 8 fibers arranged in a single-row ferrule
Polarity method: Type A (straight-through mapping)
Cable jacket options: Available in OFNR, OFNP, or LSZH, with fiber type color coding (e.g., aqua for OM3/OM4, yellow for OS2, lime green for OM5)
High precision ferrule: Ensures accurate core-to-core alignment for multimode or single-mode fibers

MTP Jumper Cable Applications

Parallel optics transmission: Ideal for 40GBASE-SR4 and 100GBASE-SR4 Ethernet links
Data center backbone cabling: Connects patch panels, cassettes, or active equipment with high-density interconnects
Breakout solutions: Can be used with MTP®-to-LC harness cables to connect 8-fiber ports to multiple duplex transceivers

MTP jumper 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 jumper cable Test Series

MTP Jumper 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 Jumper 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 jumper 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. ‌ ‌
