With the increasing demand for high-speed connectivity, it is essential to understand the importance of core numbers in MTP/MPO cables. In this guide, we will explore the significance of core numbers and provide valuable insights to help you decide when selecting the right MTP/MPO cable for your specific needs. Whether setting up a data center or upgrading your existing network infrastructure, this article will serve as a comprehensive resource to assist you in choosing the right MTP/MPO cable.

What is an MTP/MPO cable

An MTP/MPO cable is a high-density fiber optic cable that is commonly used in data centers and telecommunications networks. It is designed to provide a quick and efficient way to connect multiple fibers in a single connector.

MPO and MTP cables have many attributes in common, which is why both are so popular. The key defining characteristic is that these cables have pre-terminated fibers with standardized connectors. While other fiber optic cables have to be painstakingly arrayed and installed at each node in a data center, these cables are practically plug-and-play. To have that convenience while still providing the highest levels of performance makes them a top choice for many data center applications.

How Many Types of MTP/MPO cables

MTP/MPO cables consist of connectors and optical fibers ready to connect. When it comes to types, MTP/MPO fiber cables fall on MTP/MPO trunk cables and MTP/MPO harness/breakout cables.

MTP/MPO trunk cables

MTP/MPO trunk cables, typically used for creating backbone and horizontal interconnections, have an MTP/MPO connector on both ends and are available from 8 fibers up to 48 in one cable.

MTP/MPO Harness/Breakout Cables

Harness/Breakout cables are used to break out the MTP/MPO connector into individual connectors, allowing for easy connection to equipment. MTP/MPO conversion cables are used to convert between different connector types, such as MTP to LC or MTP to SC.

The MTP/MPO cables also come in different configurations, such as 8-core, 12-core, 16-core, 32-core, and more, depending on the specific needs of the application. This flexibility in configurations enables users to tailor their choices according to the scale and performance requirements of their networks or data centers. As technology advances, the configurations of MTP/MPO cables continually evolve to meet the increasing demands of data transmission.

How to Choose MTP/MPO cables

Selecting the appropriate core number for MTP/MPO cables resonates throughout the efficiency and performance of networks. In this section, we’ll delve into the decision-making factors surrounding core numbers in cables.

Network Requirements and Data Transmission Goals

Different network applications and data transmission needs may require varying numbers of cores. High-density data centers might necessitate more cores to support large-capacity data transmission, while smaller networks may require fewer cores.

Compatibility with Existing Infrastructure

When choosing the core number for MTP/MPO cables, compatibility with existing infrastructure is crucial. Ensuring that the new cables match existing fiber optic equipment and connectors helps avoid unnecessary compatibility issues.

Consideration for Future Scalability

As businesses grow and technology advances, future network demands may increase. Choosing MTP/MPO cables with a larger number of cores allows for future expansion and upgrades.

Budget and Resource Constraints

Budget and resources also play a role in core number selection. Cables with a larger number of cores tend to be more expensive, while cables with fewer cores may be more cost-effective. Therefore, finding a balance between actual requirements and the available budget is essential.

40G MTP/MPO Cabling

A 12-fiber MTP/MPO connector interface can accommodate 40G, which is usually used in a 40G data center. The typical implementations of MTP/MPO plug-and-play systems split a 12-fiber trunk into six channels that run up to 10 Gigabit Ethernet (depending on the length of the cable). 40G system uses a 12-fiber trunk to create a Tx/Rx link, dedicating 4 fibers for 10G each of upstream transmit, and 4 fibers for 10G each of downstream receive.

40G-10G Connection

In this scenario, a 40G QSFP+ port on the FS S5850 48S6Q switch is split up into 4 10G channels. An 8-fiber MTP-LC harness cable connects the 40G side with its MTP connector and the four LC connectors link with the 10G side.

40G-40G Connection

As shown below, a 12-fiber MTP trunk cable is used to connect two 40G optical transceivers to realize the 40G to 40G connection between the two switches. The connection method can also be applied to a 100G-100G connection.

The 12-core MTP/MPO cables can also be used for 100G parallel to parallel connection. Through the use of MTP patch panels, network reliability is enhanced, ensuring the normal operation of other channels even if a particular channel experiences a failure. Additionally, by increasing the number of parallel channels, it can meet the continuously growing data demands. This flexibility is crucial for adapting to future network expansions.

100G PMS4 Parallel BASE-8 over Singmode Fibre

QSFP28 100G PMS4 are often connected directly together due to their proximity within switching areas.

Equally QSFP28 ports are often connected directly to SFP28 25G ports within the same rack. For example, from a switch 100G port to four different servers with 25G ports.

200G MTP/MPO Cabling

Although most equipment manufacturers (Cisco, Juniper, Arista, etc) are bypassing 200G and jumping from 100G to 400G, there are still some 200G QSFP-DD transceivers on the market, like FS QSFP56-SR4-200G and QSFP-FR4-200G.

200G-to-200G links

MTP (MPO) 12 fiber enables the connection of 2xQSFP56-SR4-200G to each other.

400G MTP/MPO Cabling

MTP/MPO cables with multi-core connectors are used for optical transceiver connection. There are 4 different types of application scenarios for 400G MTP/MPO cables. Common MTP/MPO patch cables include 8-fiber, 12-core, and 16-core. 8-core or 12-core MTP/MPO single-mode fiber patch cable is usually used to complete the direct connection of two 400G-DR4 optical transceivers. 16-core MTP/MPO fiber patch cable can be used to connect 400G-SR8 optical transceivers to 200G QSFP56 SR4 optical transceivers, and can also be used to connect 400G-8x50G to 400G-4x100G transceivers. The 8-core MTP to 4-core LC duplex fiber patch cable is used to connect the 400G-DR4 optical transceiver with a 100G-DR optical transceiver.

What is Fiber Optic Patch Cable

Posted on by

Fiber optic patch cable is also known as optical fiber jumper or optical patch cord. It is composed of a fiber optic cable terminated with different connectors on the ends. There are two major application areas of fiber optic patch cords which are computer work station to outlet and fiber optic patch panels or optical cross connect distribution center. Single more fiber patch cables are primarily used for applications involving long distance, while multimode patch cables are the choice for most common local fiber systems because the devices for multimode are far chaper.

Fiber Patch Cords Types

Fiber optic patch cables can be divided into different types based on fiber cable mode, cable structure, connector types, connector polishing types and cable sizes.

Fiber Cable Mode:

. Single mode fiber patch cables: Single mode fiber optic patch cables use 9/125 micron bulk single mode fiber cable and single mode fiber optic connectors at both ends. Single mode fiber optic cable jacket color is usually yellow.

. Multimode fiber patch cables: Multimode fiber optic patch cable use 62.5/125 micron or 50/125 micron bulk multimode fiber cable and terminated with multimode fiber optic connectors at both ends. Multimode fiber patch cable jacket color is usually orange.

. 10Gig multimode fiber optic patch cables: 10Gig multimode fibers are specially designed 50/125 micron fiber optimized for 850nm VCSEL laser based 10Gig Ethernet. They are backward compatible with existing network equipment and provide close to three times the bandwidth of traditional 62.5/125 multimode fibers. 10 Gigabit is rated for distances up to 300 meters using 850nm Vertical Cavity Surface Emitting Lasers (VCSEL). 10Gig fiber optic cable jacket is usually aqua.

Fiber Cable Structure:

. Simplex fiber optic patch cables: Simplex fiber patch cable has one fiber and one connector on each end.

. Duplex fiber optic patch cables: Duplex fiber patch cable has two fibers and two connectors on each end. Each fiber is marked “A” or “B” or different colored connector boots are used to mark polarity.
