What Are MTP/MPO Patch Cords?

MTP/MPO patch cords are typically made of high-quality optical fiber enclosed in a protective jacket, with MTP/MPO connectors on both ends. MPO/MTP patch cords are the similar as LC/SC/FC and other fiber optic patch cords. The difference is the number of connectors and fiber cores. MPO connectors are more complex than LC/SC/FC connectors.

In the late 20th century, as data transmission rates increased and network architectures evolved, fiber optic connectors were needed that could accommodate multiple optical fibers in a single connector to save space and simplify cable management. With the growing demand for high-density fiber optic connectivity solutions in telecommunications and data center environments, Japan’s NTT developed the first MPO as a solution to this need. The MPO connector features a push-pull design and a rectangular ferrule that accommodates multiple fibers in a single connector.

With the popularity of MPO connectors, MPO is gradually standardized to ensure compatibility and interoperability between different systems.

In the early 2000s, US Conec introduced the MTP® (Multi-Fiber Termination Push-On) connector. Compared to the original MPO connector, the MTP connector has superior polishing technology, resulting in lower insertion loss and higher optical performance through controlled fiber protrusion and curvature radius.

MTP connectors also feature a patented floating ferrule design for better alignment and minimal insertion loss. They may also have a detachable housing for easier cleaning and maintenance.

Therefore, the difference between MTP connector and MPO connector is that MTP connector is actually a specific type of MPO connector. It can be understood that MTP is a proprietary version of MPO connector. MTP connectors feature improvements in polishing technology, ferrule design and performance, resulting in lower insertion loss and higher reliability than standard MPO connectors. It is the first choice for high-performance applications that meet stringent performance requirements.

Advantages of MPO/MTP Cabling Solutions

Unlike LC cabling, MPO/MTP cabling solutions perfectly meet the requirements of high-speed, high-density, and structured cabling. The specific advantages include the following:

Stability and Durability

The sleeve design of MTP connectors reduces the possibility of signal instability to some extent, enhancing durability.

High Density and Scalability

MTP connectors comply with telecommunications-grade Telcordia standards, addressing the challenge of carrying multiple fibers in a small capacity. For instance, while LC duplex connectors in a 1U chassis accommodate 144 fiber cores, MTP connectors can accommodate 864 fiber cores, nearly six times the capacity of the former.

Time and Cost Savings, High Deployment Efficiency

The time required for MPO/MTP cabling is significantly reduced. Using pre-terminated cables for plug-and-play installation saves time and effort, and lowers maintenance costs in the long run. Moreover, structured MTP cabling provides a hierarchical structure to the network, offering multiple connection options through aggregation layers to reduce cable clutter.

Preparation for Network Upgrades

MTP cabling supports direct connections for 40G-40G, 100G-100G, 200G-200G, and 400G-400G, as well as upgrades and upstream connections. Upgrading from 10G to higher Ethernet speeds like 40G/100G/120G using MPO/MTP cabling systems is common and economically reliable. Additionally, MTP cabling systems facilitate upstream connections between devices of different speeds, such as 25G-100G, 50G-200G/400G, 100G-400G, and 200G-400G.

Types of MPO Patch Cords

Trunk Patch Cord

A trunk patch cord consists of multiple MPO connectors pre-terminated on both ends with single-fiber or multi-fiber connectors. Trunk patch cords are normally used for high-density data center applications, offering quick and easy connectivity between MPO-equipped equipment.

MPO Patch Cord

The MPO connector is a type of fiber connecter. MPO (Multi-Fiber Push On) is a multi-core fiber connecter type. The MPO high -density fiber pre -connection system is currently mainly used in the application of high -density environments of data centers, the application of optical fiber to the building, and the internal connection applications inside the optical transceiver equipment such as the optical device, 40G, 100G, QSFP+.

Harness Patch Cord

Harness patch cords are designed with multiple MPO connectors on one end and individual connectors on the other end, just like breakout patch cords.  However, harness patch cords generally have shorter lengths and are used for connecting equipment inside a  rack or cabinet, providing a easy and organized cabling solution.

Fanout Patch Cord

Fanout patch cords are much like breakout patch cords but feature a fanout assembly at one end instead of individual connectors. The fanout assembly consists of numerous strands of fiber terminated with connectors such as LC, SC, or MTP/MPO. Fanout patch cords are used for connecting MPO trunk patch cords to equipment or patch panels with individual fiber ports.

MPO Fiber Optic Loopback / Cable

The MPO loop contains the MPO back ring jumping line in the LOOPBACK, and puts both ends of the fiber into an MPO connector to achieve the light path in the same connector. The launch capacity and receiving sensitivity of the device, especially in 40/100G network communication, can locate various potential phenomena by returning signals to achieve effective testing and evaluation of a single component or interface on the fiber network.

How to Choose?

Performance

Insertion loss is one of the key factors affecting the performance of fiber optic networks. The smaller the insertion loss, the better the transmission performance. Generally, the insertion loss of MTP/MPO multimode fiber patch cords should not exceed 0.6 dB, and the insertion loss of single-mode MTP/MPO fiber patch cords should not exceed 0.75 dB. However, for single-mode and multimode MTP/MPO fiber patch cords with low insertion loss (high quality), the requirement is that the insertion loss should not exceed 0.35 dB.

Jacket

The outer jacket of MTP/MPO patch cords can be made of different materials, which have different flame retardancy properties and can be divided into polyvinyl chloride (PVC), low-smoke zero halogen (LSZH), etc. Most of them have good flame retardancy. If there are higher requirements for the installation environment, such as ceiling and raised floors, it is best to choose MTP/MPO fiber patch cords with higher flame retardant grades. This makes it less likely to burn or emit smoke in the event of a fire. When purchasing MTP/MPO fiber patch cords, you can directly check the flame retardant grade on the protective jacket, and then choose the appropriate MTP/MPO fiber patch cords based on the actual application environment of the protective jacket and flame retardant grade of the fiber patch cords.

Polarity

The polarity of an MTP/MPO patch cord refers to how fibers are arranged within the connector, ensuring correct signal transmission. There are three main configurations: Type A (straight-through), Type B (reversed), and Type C (pair-wise flipped). Choosing the right polarity is crucial for compatibility with other network components.

-Type A Polarity

The fibers at one end of the patch cord are aligned in the same order as the fibers at the other end. This configuration is used for straight-through connections where the transmit (Tx) fibers at one end are connected to the corresponding receive (Rx) fibers at the other end.

Type A Polarity

-Type B Polarity

The fibers at one end of the patch cord are reversed or flipped compared to the fibers at the other end. This configuration is used for connections where the Tx fibers at one end need to be connected to the Rx fibers in reverse order at the other end.

Type B Polarity

-Type C Polarity

The fibers at one end of the patch cord are paired-wise flipped compared to the fibers at the other end. This configuration is used for connections where specific pairs of fibers need to be swapped or crossed over, while maintaining the correct transmit and receive paths.

Type C Polarity
