MTP/MPO System for Different Applications

There is no doubt that 40/100/200/400G networks become the trend in today’s cyberspace. Many applications are pursuing the high bandwidth throughput, therefore using high-density patching is inevitable. But is there any good solution for high-density structured cabling? Definitely, MTP/MPO system solves your trouble with a wide range of MTP/MPO assemblies. It is a technique enabling multi-fiber connections to be used for data transmission. The high fiber count creates the endless possibilities of high-density patching. The easy installation of MTP/MPO assemblies also saves lots of operating time. There will introduce some regular MTP/MPO products and their common applications.

Common MTP/MPO Products

To accommodate the needs for high speed networks, MTP/MPO system has many optics to fit for different applications. There are usually MTP/MPO cables, MTP/MPO cassettes, MTP/MPO optical adapter and MTP/MPO adapter panels.

MTP/MPO cables are terminated with MTP/MPO connectors at one end or both ends. The fiber types are often OM3 or OM4 or OM5 multimode optical fibers. MTP/MPO cables has three basic branches of trunk cables, harness/breakout cables and pigtail cables. MTP/MPO trunks can be made with 8, 12, 24, 36, 48, 72 or even 144 fibers for single-mode and multimode applications. MTP/MPO harness cables are usually terminated with a MTP/MPO connector at one end and different connectors, such as LC, SC, ST connectors, etc. at the other end. Pigtails only have one end terminated with a MTP/MPO connector, and the other end is used for fiber optic splicing with no termination.

As for the MTP/MPO cassettes, they are equipped with standard MTP/MPO connectors to be deployed in an ODF (optical distribution frame) for high-density MDA (main distribution area) and EDA (equipment distribution area) in data centers.

Other components like the black-colored MTP/MPO optical adapter and adapter panels build the connection between MTP/MPO cable to cable or cable to equipment.

The Advantages of MPO/MTP Solutions

As the new favorite of data center, the MPO/MTP solutions feature the following advantages:

Rapid Deployment

Since the MPO/MTP products are factory terminated, they can be installed easily and simply. They use a simple push-pull latching mechanism for easy and intuitive insertion and removal. Thus, the installing process only includes pull and plug, eliminating all unpredictable field termination troubles. It is estimated that the MPO/MTP solutions’ installation time can be reduced by up to 75% compared to traditional fiber cabling systems.

High Density

Being the same size as a SC connector, the MPO/MTP connector can accommodate 12/24 fibers, providing 12/24 times the density. Therefore, MPO/MTP connectors allow high-density connections between network equipment in telecommunication rooms, and offer savings in circuit card and rack space.

Cost Saving

As mentioned above, the installation process of MPO/MTP products is simple and easy. Therefore, the installation time involving a costly highly qualified workforce can be reduced to a minimum.

Scalability

As we all know, most MPO/MTP products are modular solutions. This is the good choice to ease future expansion and for quick and easy system reconfiguration.

Why MPO/MTP Solutions Are Needed in Data Center?

With the advent and popularity of cloud computing and big data, the demands for high-speed transmission and data capacity are becoming much greater than ever before. And 40/100/200/400G Ethernet is now a trend and hotspot for data center cabling system. Since MPO/MTP connectors are the up-and-coming standard optical interface for 40/100/200/400G Ethernet network, it is predicted that MPO/MTP solutions will eventually flood the data center. After all, the high fiber count in one connector creates endless possibilities.

Why is the MTP Connector Described as A High Performance MPO Connector?

There are features on the MTP connector that have been specially designed to give improved performance and better usability over generic MPO connectors. These design features are unique to the MTP and are patent protected. The key features are described below:

1. The MTP connector housing is removable.

Re-work and re-polish of the MT ferrule ensures overlife performance.
The gender can be changed after assembly or even in the ﬁeld giving ﬂexibility at point of use.
The ferrule is scanned interferometrically after assembly.

2. The MTP connector offers ferrule ﬂoat to improve mechanical performance.

This allows two mated ferruled to maintain physical contact while under an applied load. (US Patent 6,085,003)

3. The MTP connector uses tightly held tolerance stainless steel elliptical guide pin tips. The elliptical shaped guide pin tips improve guidance and reduces guide hole wear. (US Patent 6,886,988)

4. The MTP connector has a metal pin clamp with features for centering the push spring. This feature:

Eliminates lost pins

Centers the spring force

Eliminates ﬁber damage from the spring mechanism

5. The MTP connector spring design maximizes ribbon clearance for twelve ﬁbers and multiﬁber ribbon applications to prevent ﬁber damage.

6. The MTP connector is offered with four standard variations strain relief boot giving more ﬂexibility over the cable used

A round loose ﬁber cable construction

MTP® vs MPO Connectors Compare MTP to generic MPO connectors MTP® or MPO, What’s In A Name?

MPO is the industry acronym for “multi-ﬁber push on.” MPO connectors have more than 1 ﬁber in a single ferrule and snap into place by a mechanical mechanism.

The MTP Connector is one brand of MPO connector.

Due to the difficulties in mating two connectors with multiple fibers, as opposed to using single fiber connectors such as an LC connector, different brands of MPO give different performance.

MPO

The term MPO stands for Multi-fiber Push On and is a specific interface type. The MPO interface was developed to enable multi-fiber connectivity for higher density, higher bandwidth based applications requiring parallel or channel based optics. 12 and 24 fiber versions are currently used to direct connect into 40G and 100G transceivers and also used in high density fiber distribution areas. Higher fiber versions are also available (48, 72 fiber) but their use and deployment is currently limited.

MTP®

The MTP® connector is specifically a brand of MPO interface connector that is owned by the leading US based optical R&D company US Conec. Like MPO it is based on the MT (mechanical transfer) ferrule technology which was developed by Nippon Telephone and Telegraph (NTT) during the 1980s.

MTP® Design Features

A floating ferrule that aids in accurate alignment and improves performance of mated ferrules under stressed load conditions.

Elliptical guide pins that allows for better alignment by improving mating guidance and reducing hole wear.

Removable housing allowing for smoother transition of gender types in the field and easier access to performance testing and re-work of the MT ferrule.

The MTP® connector has a metal pin clamp that centers and guides the push spring. This feature eliminates lost guide pins, centers the spring force and eliminates damage to fiber cables from the spring.

The MTP® connector spring design maximizes ribbon clearance for twelve fiber and multi-fiber ribbon applications to prevent fiber damage.

The MTP® connector is offered with four standard variations of strain relief boots to meet a wide array of applications.

The MTP® connector is currently available in 4, 8, 12, 24, and 72 fibers densities for multimode fiber (50µm and 62.5µm core) and 4, 8, 12, and 24 fibers densities for single-mode fiber, as well as the MTP® Elite® (low-loss) single-mode connector in both 8 and 12 fibers densities. It is also important to note that the MTP® connector complies with the MPO standard as outlined in IEC standard 61754-7 and TI-604-5 and is therefore a fully compliant MPO connector and can interconnect directly with other MPO based infrastructures.

MTP® Connectors and MPO Connectors

MPO is the industry acronym for “multi-ﬁber push on.” MPO connectors have more than 1 ﬁber in a single ferrule and snap into place by a mechanical mechanism.

The MTP Connector is one brand of MPO connector.

Due to the difficulties in mating two connectors with multiple fibers, as opposed to using single fiber connectors such as an LC connector, different brands of MPO give different performance.

Typically, MPO connectors have had 12 fibers or multiples of 12 fibers (24, 48, 72). However, recently 8 fiber MPO connectors are being introduced to accommodate the uptake of BASE-8.

There are many designs of MPO on the market from the various manufacturers. The high end performance marketplace is dominated by the MTP connector. This connector offers reliable performance and the MT ferrule used in the connector is also used by many brands of equipment (CISCO, Brocade etc.) within their transceivers. By using the same ferrule in the transceiver and the connector cable ensures the highest performance.

We believe the market leading MPO connector in terms of performance and durability is the MTP® connector produced by US Conec – which is why our range is standardised on this product and is also probably why the connector is used by many other brands including Corning, Systimax by Commscope, TYCO Amp Net Connect / ADC Krone, Panduit, Siemon and many others.

MTP Connector Further Information

Are MT Ferrules Cleaned in the Same Way as Standard Connectors?

The best method available for cleaning MT ferrules to remove dust and oils which reduce optical performance is the use of an advanced dry cloth cleaning system like the IBC branded cleaning tool or an NTT-AT OPTIPOP.

The cleaning method is very simple as it involves a single pass. When using the recommended cleaning system contaminants are completely removed as opposed to using low grade cloths or swabs which just move the contaminants away from the ﬁbers but leave them on the ferrule face.

1. The click cleaners and OPTIPOP family of cleaners are designed for use with both male and female connections and have options for single ﬁber ceramic ferrule connectors as well

2. The OPTIPOP cassette and card cleaners allow the owner to reﬁll the cleaning clothes which can reduce cost per cleaning below traditional cleaning methods.

MTP® Connector Features

There are two aspects to the connector; the housing and the ferrule. There are multiple options of both which are used for different ﬁber core counts and different construction cables.

MT stands for mechanical transfer and an MT ferrule is a multi-ﬁber (usually 12 ﬁbers) ferrule. The performance of the connector is determined by the ﬁber alignment and how this alignment is maintained after connection. Ultimately, the alignment is determined by the eccentricity and pitch of the ﬁber and how accurately the guide pins keep the ﬁbers together during mating. The performance of any MPO connector can be improved if the tolerances of the pins and the moulding processes are reduced during manufacture.
