MPO fiber connector is a passive component for optical fiber cable connection. It has been widely used in many projects and plays an important role in the optical fiber transmission system. In order to give full play to the role of MPO fiber connector in engineering applications, technicians should pay attention to the main structure and features of this connector, and master the basic working principle of MPO fiber connector so that the application of MPO fiber connector can be better put in practice and the development and innovation of optical fiber transmission system can be better promoted.
You may also see the term MTP used interchangeably with MPO. The term MTP is a registered trademark of the MPO connector offered by US Conec. The MTP is fully compliant with MPO standards and is described by US Conec as an MPO that has been engineered to very tight tolerances for improved performance. For the purpose of this discussion, we will refer to only MPO connectors since MTP connectors are considered to be MPO connectors.
Structure of MPO Fiber Connector
MPO is short for the industry acronym— “multi-fiber push on”. The MPO connector is a multi-fiber, and multichannel pluggable connector which is most commonly defined by two documents: IEC-61754-7 (the commonly sited standard for MPO connectors internationally) and EIA/TIA-604-5 (also known as FOCIS 5, is the most common standard sited for in the US). It is made up of a male plug , a female plug, and an adapter. The end of the male plug has two guide pins and a maximum of 72 guide holes, but the most common are 12 holes. When mating the connector, the spring mounted at the end of the core insert will provide a thrust on the core insert to lock it up with the adapter. The guide pins of the plug can restrict the relative position between the connectors, and ensure the optical fiber mating sequence is correct.
Features & Specifications
MPO connectors utilize precision molded MT ferrules, with metal guide pins and precise housing dimensions to ensure fiber alignment when mating. The MPO can be mass terminated in combinations of 4, 8, or 12 fiber ribbon cables. The MPO adapter comes standard in black. The single mode or multimode MPO products available from fiber-mart.COM are multifiber connections used in high-density backplane and Printed Circuit Board (PCB) applications in data and telecommunications system. The MPO connector, combined with lightweight ribbon cable, represents a huge technological advance over traditional multifiber cables. It’s lighter, more compact, easier to install, and less expensive, and it has lower insertion loss over traditional multifiber cables.
Application of MPO Fiber Connector
As mentioned, MPO connectors are compatible ribbon fiber connectors. MPO fiber connectors cannot be field terminated, thus MPO connector is usually assembled with fiber optic cable. MPO fiber optic cable is one of the most popular MPO fiber optic cable assemblies, which are now being widely used in data center to provide quick and reliable operation during signal transmission. MPO connectors can be found in the following applications:
CATV and Multimedia
Active Device Interface
Optical Switch interframe connections
Interconnection for O/E modules
Industrial & Medical, etc.
Considerations to Select MPO Fiber Connector
With the drive of market requests. Various types of MPO connectors are being provided. Some basic aspects should be considered during the selection of a MPO connector. Firstly, pin option. MPO connectors have male and female design (as showed in the figure 1). Male connectors have two guide pins and female connectors do not. Alignment between mating ferrules of MPO connectors is accomplished using two precision guide pins that are pre-installed into the designated male connector. Secondly, fiber count. MPO connector could provide 4, 6, 8, 12, 24, 36, 64 or more interconnections, among which 12 and 24 are the most popular MPO connectors. In addition, like other fiber optic connectors, the selection of MPO fiber connectors should also consider fiber type and simplex or duplex design.
According to aforementioned introduction, we can see that MPO connector plays an important role in optical telecommunication as well as the high-density cabling solutions. If you are preparing to deploy network, it’s advisable that you can purchase quality MPO connector, MPO cables and MPO cassettes from fiber-mart.COM.
