How to Choose a Quality MTP/MPO Cable ?

MTP /MPO cables are helping the digital world by enabling densely packed, multi-lane connections between Data Storage and Distribution points.It is anticipated that the number of connections using MPO cables will increase as the 5G New Radio Metro Transport Network is implemented.On the other hand, when it comes to MTP MPO cables, the process is more complex and requires a basic understanding of the features and applications.

In this article, we will discuss how to spot a quality MTP cable in the market.

Factors to Consider When Choosing an MTP/MPO Cable

There are many factors to consider when choosing the best MTP cable.A good MTP cable should have these five main features.

Branded Fiber Core to Ensure Best Performance

The deployment of MTP/MPO networks is often limited by space constraints, such as distribution boxes for telecommunications and data center cabinets.When this happens, the fiber core is bent at an angle.Poor fiber cores can cause signal loss and high transmission interruption if they are bent at small angles.The bending performance of Corning ClearCurve fiber offers greatly improved signal fidelity, allowing for faster, more efficient cabling and routing.Hence, it is very important to use MTP cables which have branded fiber cores.

Industry Recognized MTP Connector is Significant

Fiber connector MTP/MPO can package 12, 24, or 72 fibers into a ferrule to improve fiber density.Because of this, they are commonly used in small data centers.Using industry-recognized connectors such as the US Conec or Senko connector can help eliminate insertion and return losses by providing precise alignment of the female and male sides.It is designed to be durable enough to meet hundreds of mating cycles.It is possible to route and mechanically load a round multi-core cable from any direction of the MTP connector port for installation of the connector and the wire.Therefore, in order to purchase the best MTP cable, it is necessary to purchase a connector that is industry-recognized.

Low Insertion Loss is a Key Factor

A connector or plug inserted into a link will cause an insertion loss (IL).Fiber optic networks are impacted by this factor in a significant way.If the insertion loss is low, the performance of the network is better.Usually, multimode MTP ferrules have an IL no greater than 0.6 dB, and single-mode MTP ferrules have an IL of 0.75 DB.It is generally necessary that the insertion loss (high quality) be less than 0.35 dB for single-mode and multi-mode MTP.You can choose vendors who provide insertion loss report when choosing MTP cables.

It Is Important to Consider the Flame Retardant Grade

Various materials are available for the jackets of MTP cables, each of which has its own features and is suitable for different scenarios.There are several types of materials that have good flame retardant properties, including PE, PVC, LSZH, Plenum, and Riser.It is best to choose a high flame retardant level when the installation environment is more challenging, such as in drop ceilings and raised floors, so that the materials will not easily burn or smoke in the event of a fire.Below you will find a table showing how to gauge the flame retardant grade of various jacket materials and applications.


Flame Retardant Level

Application Scenarios

Possible Substitute


Rank 1 (Highest)

Horizontal wiring area and aerated environment (conveying pipes, air handling systems, etc.)

Can't be replaced by cables with lower ratings


Rank 2 (Middle)

Vertical wiring area (connection between entrance equipment or computer room and communication cabinets on different floors)



Rank 3 (Lower)

Common area


Fiber Cable Testing Should Be Done Strictly

For securing quality and performance, IEC 61300-3-35 was created by the International Electrotechnical Commission (IEC).Connector end faces must follow the requirements of this standard before connection.For each zone inside the connection, there are requirements regarding scratches and defects.In addition to non-linear defects, the fiber must also have particulates, other debris, pits, chips and edge chipping.A good cable is one with a clean end face.
