MPO / MTP Fiber Optic Cables

MPO（Multi-fiber Push On）connector was originally developed in an attempt to reduce the amount of time required for fusion splicing individual connectors. The MTP connector is a high performance MPO connector in complete compliance with all MPO connector standards. The basic MPO trunk cables are available in 8, 12 and 24-fiber
variants. These MPO systems have evolved over time and now provide support for a large variety of network topologies.

Multimode MPO / MTP fiber cables are intended to carry multiple signals at once, typically have flat ends. Single mode MPO/MTP fiber cable is designed to carry only one signal with angled ends to minimize back-reflection, increasing the bandwidth exponentially. we have both female type and male type MTP/MPO connectors. the MTP / MPO fiber patch cables jacket are Mini-Core Plenum (OFNP), Mini-Core Riser (OFNR), Mini-Core Low Smoke Zero Halogen (LSZH) types optional. the optical fiber types available is G652D OS2 single mode, G657 single mode bend insensitive, multimode OM1, OM2, OM3, OM4 and OM5.

MPO Connector Polarity

The ANSI/TIA 568-3.D, (Optical Fiber Cabling and Components Standard, October 2016) defines three pinning or types for multi-fiber array systems: Method A, B and C. While one method is not preferred over another, the standard recommends that you choose a method in advance and use it throughout your installation. To maintain the proper polarity, there are three connectivity methods—A, B, C—that mirror the cable types. Each polarity method handles the transition from transmit to receive in a different manner.

  • Method A, straight-through, is the most commonly used approach. It is pin 1 to pin 1 and uses Method A (key-up to key-down) MPO connectors.
  • Method B is a crossover method (pin 1 to pin 12) and uses method B (key-up to key-up) MPO connectors.
  • Method C uses flipped pairs (pin 1 to pin 2) and method A (key-up to key-down) MPO connectors. It does not offer a migration pathway to 40-/100-GbE.

MPO/ MTP Fiber Optic Cable FAQs

MPO is the industry acronym for “multi-fiber push on.” The MPO-style connectors are most commonly defined by two different documents:
  • IEC 61754-7-1 and IEC 61754-7-2 are the commonly cited standards for MPO connectors internationally
  • TIA-604-5, also known as FOCIS 5, is the most common standard cited in the US
The MTP connector is a high performance MPO connector with multiple engineered product enhancements to improve optical and mechanical performance when compared to generic MPO connectors.
The MTP connector is in complete compliance with all MPO connector standards including the TIA-604-5 FOCIS 5, IEC 61754-7-1 and IEC 61754-7-2. The MTP connector is intermateable with all generic MPO-style connectors that are compliant to these industry standards. Generic MPO connectors are limited in performance and are not able to offer the high performance levels of the US Conec MTP connector.
Yes. The MTP connector is a high performance MPO connector engineered for better mechanical and optical performance.
MTP connectors are high performance MPO connectors designed for better mechanical and optical performance. With removable housing feature, MTP connectors allow changing, re-polishing or interferometrically scanning the MT ferrule or even changing the gender of the connector after assembly or in the field.
An MTP connector has a floating ferrule, which improves mechanical performance. This means that two mated ferrules can maintain physical contact while under load. MPO connectors have plastic pin clamp and round spring, but MTP connectors have metal pin clamp and round spring. Furthermore, having a metal pin clamp allows the push spring on the MTP connector to always stay centered. This feature prevents losing pins, centralizes the spring and protects it from any potential damage. The guide hole wear in MPO connectors may appear after about 50 parings. However, with MTP connectors, that range is improved to 500 pairings.
The rapid increase in the number of network links in the data centers can cause the data center of conventional fiber cabling to become cramped and difficult to manage. To solve this problem, data centers must obtain ultra-density to accommodate all the cabling used in the cabling.
Advantages: MPO/MTP cables, which combine 8, 12 or 24 fibers in a single interface, have proven to be a practical solution for that problem. In addition, the MTP/MPO multi-fiber cable connectors can accommodate 8, 12 or 24 fiber in the same area needed for an SC connector, meeting the 40GBASE-SR4 and 100GBASE-SR10 standards, and eventually, MPO connectors can effectively save card and rack space.
Disadvantage:An MPO/MTP connector has a very sensitive surface that cannot be cleaned easily.
To establish an MPO connection between two MPO cables, an MPO adapter is a must and the connectors should have opposing types. Which means only male to female connection is possible, not male-male or female-female. If a female connector is used on both sides of the adapter the performance would be very low because without male pins the fibers would not be aligned. On the other hand using two male connectors is not possible and might damage the connectors.
After MPO cables are produced, they get cleaned and assessed both microscopically and geometrically to ensure they are clean and with high quality.
A MPO test device is used to measure light transmittance and make sure the fiber connectors are providing standard values. In order to do the measurement.
We need 1 jumper cable fixed to the device, 1 master cable determined by the type of cable we seek to measure and the actual measured DUT cable.
The cables must be clean before the measurement and with the master cable in mind.
Afterwards, the measured cable is connected to master cable and the device in order to be tested, and a precise reading with the final measurement result is given by the device.
The method for cleaning MPO connectors is to inspect, clean, and reinspect.

Inspect—Always inspect the connector first. You don’t need to clean a connector if it’s already clean, as cleaning it might actually make it dirty. This is especially true for MPO connectors, which are highly sensitive. For example, for an MPO-24, dirt from the first row could potentially migrate to the second row while cleaning.
Make sure to inspect both mating connectors, as residue from a dirty connector will transfer to a perfectly clean connector once they mate. High-performance inspection tools and solutions on the market are better than ever. They allow you to do the following.
  • Inspect single-fiber and multifiber cables using the same tool by simply switching the adapter
  • Take advantage of a slim design to easily access recessed connectors and dense panel settings
  • Get an automated analysis of all fibers or multifiber cables and obtain a clear pass-or-fail result according to your testconfiguration

Clean—If the connector is dirty, first try the dry method. If the dry method fails to remove the dirt, try the hybrid cleaning method, which involves using a solvent. Reinspect—Always dry your connector after using wet cleaning tools and always reinspect the connector. Simply looking at an image to determine if a fiber is clean can be difficult and subjective. Automated analysis makes testing easy, eliminates guesswork, complies with standards and provides consistent results for all technicians regardless of differences in experience or training. And, by generating a report of your results, you make sure to leave a record of testing and avoid unnecessary troubleshooting in the future.
