1. Optical Performance

A. Insertion Loss (IL) & Return Loss (RL)

(1) Low Insertion Loss (IL): High-quality MTP®/MPO cables should have an IL of ≤ 0.35dB for Elite (premium) versions and ≤ 0.7 dB for standard versions.

(2) High Return Loss (RL):

Multimode fibers (OM3, OM4, OM5) should have RL ≥ 20 dB.

Single-mode fibers (OS2) should have RL ≥ 40 dB.

(3) Testing Required: Ensure that IL and RL are tested using an optical loss test set (OLTS) or optical time-domain reflectometer (OTDR).

B. 3D Interferometer Testing

(1) High-quality MTP®/MPO connectors undergo 3D interferometric testing to measure:

End-face geometry (radius of curvature, core height, apex offset).

Criticality: MPO cable assembly contain multiple fiber cores (such as 12-core, 24-core), and it is necessary to ensure that all fiber cores are accurately connected.
Standard: Use high-precision guide pins (PIN) and molds to avoid deviation (preferably within ±1μm). Yingda uses SENKO and USCONEC original guide pins, or domestic FSG or three-circle high-quality guide pins to ensure that all products are of the highest quality.
Impact: Poor alignment can lead to increased insertion loss or signal crosstalk.

D. Fiber Optic Patchcord Testing

MTP/MPO fibre optic patchcord connector end face testing: To ensure that fibre optic connectors are qualified or better, the International Electrotechnical Commission (IEC) has developed the IEC 61300-3-35 standard to define connector end face qualification. It has requirements for scratches and imperfections in each area inside the connection. Scratches represent permanent linear surface features.

How to Identify High-Quality MTP MPO Patch Cable?

With the increasing demand for high-speed transmission and high-density wiring such as big data, data centers, AI artificial intelligence and computing centers, 5G, etc., the application of MTP cable has been doubling in recent years. The quality of MPO fiber jumpers determines the stability and sustainability of the entire data center network.

Therefore, how to choose good quality MTP patch cable is crucial. What are the main characteristics of good quality MPO MTP patch cable, and how should they be measured? Below we will introduce to you the selection guide for MTP patch cable.

To distinguish high-quality MTP®/MPO cables from lower-quality alternatives, consider the following key factors:
