MTP/MPO Overview: Everything you need to know

Fiber Optic Jargon MTP/MPO Fiber Optics





An MTP/MPO Overview

 
In the ever-evolving world of telecommunications and data centers, the demand for faster and more efficient network solutions continues to rise. 
 
Fiber optics, with its ability to transmit data at the speed of light, plays a crucial role in meeting these demands. 
 
One key advancement in fiber optic technology is the use of Multi-Fiber Push On (MTP) or Multi-Fiber Push On (MPO) cables. Both of these terms are interchangeable so you may see one or the other.
 
MTP connector is a trademark by US Conec for a version with improved specifications.
 
This blog post will provide a comprehensive overview of MTP/MPO connectors, their applications, differences, testing, and more.
 

What is MTP in Fiber Optics?

 
MTP, short for Multi-Fiber Push On, is a type of connector commonly used in high-density applications where multiple fibers need to be connected quickly and efficiently. 
 
It's designed to accommodate multiple fibers in a single connector, thus reducing the complexity of cabling systems. 
 
MTP connectors are widely used in data centers, enterprise networks, and telecommunications infrastructure.
 

When Would I Need MTP vs Other Fiber Optic Setups?

 
MTP connectors are particularly beneficial when dealing with high-density environments. 
 
If you have a data center or a network setup that requires numerous connections in a limited space, MTP solutions are the way to go. 
 
Traditional single-fiber connectors, while still relevant for certain applications, can't match the speed and efficiency of MTP connectors when it comes to connecting multiple fibers.
 

How to Test MTP/MPO Cables?

 
Testing MTP/MPO cables is essential to ensure proper connectivity and performance. 
 
Since these cables carry multiple fibers, testing can be more complex compared to single-fiber cables. 
 
Specialized test equipment is required to measure parameters like insertion loss and return loss. 
 
Regular testing helps identify and rectify any issues in the cabling infrastructure.
 

What types of MTP and MPO connectors are there?

 

MTP 8 fiber connectors

 
MTP 8 Fiber Connectors are designed to connect multiple fiber cables in a single cable. 
 
They allow for fast and easy installation of data networks or other broadcast systems, while also providing reliable connectivity with minimal signal loss. 
 
The MTP 8 Fiber Connector is built to meet industry standards, ensuring compatibility with most network applications. 
 

MTP 12/24 fiber

The most commonly used MTP connector is the 12 fiber connector, which is designed to terminate both single mode and multimode fibers. 
 
This type of connector offers excellent performance and reliability, allowing for a low-loss connection with minimal disruption to signal integrity.

How to Clean MTP/MPO Connectors?

 
Maintaining clean connectors is crucial for optimal signal transmission. 
 
Contaminants like dust and oil can significantly degrade performance by slowing down or inhibiting the signal quality. 
 
You’ll want to clean your fiber connectors prior to mating and when you remove/reinsert connections.  This is because the connectors can become statically charged and may attract dust when exposed to air.
 
Cleaning MTP/MPO connectors requires precision and the use of appropriate cleaning tools and solvents. 
 
A 200 or 400 power microscope is important to help you clean so you can see dried liquid compounds or others that need to be dealt with when cleaning.
 
Regular cleaning, along with proper inspection, can prevent signal loss and ensure the longevity of your network.
 
 
 

What is Polarity in MTP/MPO Cabling System?

 
Polarity in MTP/MPO systems refers to the proper alignment of fibers to ensure accurate data transmission. 
 
 
There are three polarity methods: Type A, Type B, and Type C. 
 
Choosing the right polarity method depends on the network's requirements and the type of equipment being used. 
 
Proper polarity management is crucial for avoiding signal loss and ensuring efficient communication.
 
 

Connector MPO Structure

 
MPO connectors have a unique structure designed to accommodate multiple fibers. 
 
They consist of a housing, ferrule, guide pins, and a spring mechanism. 
 
The design ensures precise alignment and connection between fibers. 
 
Understanding the structure helps in handling and maintaining these connectors properly.
 

What is an MTP Fanout Assembly?

 
An MTP fanout assembly is a cable assembly that transitions from an MTP connector on one end to individual connectors (such as LC or SC) on the other end. 
 
It’s designed to take your MTP trunk assembly and convert it to standard fiber optic simplex connectors.
 
This allows the connection between high-density MTP cabling and devices that require standard connectors. 
 
MTP fanout assemblies offer versatility and compatibility in complex network setups.
 

What Are MTP Cassettes?

 
MTP cassettes are modular units that house MTP/MPO connectors on one side and individual connectors on the other. 
 
They provide a transition point between backbone cabling and equipment cabling. 
 
MTP cassettes are commonly used in data centers to manage high-density connections efficiently.
 

Do I Need Multimode or Singlemode?

 
The choice between multimode and singlemode fiber depends on the distance and bandwidth requirements of your network. 
 
Multimode fiber is suitable for shorter distances within buildings, while singlemode fiber is designed for longer distances.
 

What Type of Jacket Do I Need for My MTP Assembly?

 

The type of jacket you choose for your MTP assembly depends on the environment in which it will be installed. 
 
Plenum, riser, and LSZH (Low Smoke Zero Halogen) are common jacket types, each with specific fire and safety ratings. 
 
Selecting the appropriate jacket ensures compliance with building codes and regulations.
