Data center is still the focus of CIOE2015

During CIOE2015, data center continues to hot, is still the focus of this exhibition, almost all manufacturers are playing jumpers "MPO/MTP" connector slogan, illustrates the market hot.

According to communication with the industry during the exhibition, it has been used to obtain the data center optical modules and jumpers, almost exclusively from Google and Alibaba orders. It is said that there are two companies in Shenzhen to carve a fortune from Google about 500 million yuan of large orders, production line capacity can be filled.

But this exhibition, still no shortage of new entrants into the ceramic ferrule producers, they do not see the momentum MPO/MTP it? Hunan Zhongke, said progress over the past year in the Division is very good, the current production capacity has been insufficient to support current customers, the future they will continue to expand production, the initial period is for them to quickly capture share, as to whether the investment in the future MT ferrule remains to be market conditions.

Jiangsu and Zhejiang Provinces ceramic ferrule manufacturers have said that domestic orders data center demand has not really released, are expected to erupt in 2017. This year the fiber link is still grown exponentially increase demand for ceramic ferrule, therefore, do not worry about the problem of production capacity in a short time can not be consumed, even to consider expansion. And MT ferrule technology threshold is also higher, domestic enterprises temporarily unable to fully grasp the techniques.

However, we still find Dongguan Zongxia communication, this year continue pushing its MT ferrule, which is the only one to focus MT ferrule and the external display. After CIOE2014 Dongguan Zongxia debut MPO ferrule sample, by the industry concerned, after a year of continuous research and repeated tests, the relevant responsible person said, MT ferrule since May this year after the official launch of the market, now we have a certain shipments, a lot of good customer feedback.

MPO Connector and MTP connector

With the rapid development of data centers, cloud computing, cloud storage and other applications gradually penetrated the bandwidth requirements of each industry, network communication also will increase rapidly, while the high speed, high capacity, high-bandwidth often requires more space and higher costs, which exist this long-term contradiction, MTP/MPO fiber optic wiring standard has become the best solution for the current density and high bandwidth. MTP and MPO market today exist two kinds of fiber optic connection system, they are very similar to some extent, mutually compatible, and that they really tell the difference.

MPO (Multi-fiber Pull Off) is Japan's NTT Communications designed the first generation of shrapnel clamping type multi-core optical fiber connector, is the name of several companies now produce a multi-pin connector head. The MTP, by the United States USConec company registered the brand, specifically refers to the production of unique MPO connector type.

What is the MPO connector?

MPO is a "multi-fiber pull off" the abbreviation. This connector ferrule has more than one core, by mechanical means snaps into place.
Now various manufacturers on a market multiple MPO design, different types of connectivity products, its performance and cost are very different. Some of the performance characteristics of the product to make it more prominent, and some MPO connector can be matched with many different brands of products, but some are not, this depends on how close the interworking of these connector design with standard products. MPO connector complete definition, refer to the implementation of IEC-61754-7 and EIA / TIA-604-5 (aka FOCIS 5).

What is a MTP connector?

MTP connector is an innovative design with multiple high performance MPO connector with respect to the average for the MPO connector, MTP fiber optic connector on the optical and mechanical properties have been strengthened. MTP connectors are fully compliant with all MPO connector professional standards, including EIA / TIA-604-5 FOCIS 5 and IEC-61754-7.

MPO connector is consistent with industry standards mutual pairable MTP connector, which means replacing the MPO connector with MTP connector for better performance is possible. Most follow the MPO connector of old design performance is quite limited, it can not provide the same high performance with MTP connector.

Why MTP connector is described as a high performance MPO connector?

Through a specially designed MTP connector performance and availability were improved compared with MPO connectors. This design feature MTP is unique and protected by patents. The main features are as follows:

1, MTP fiber optic connector sleeve frame parts can be easily removed.

MT ferrule design can be reworked and re-grinding in the production of energy to ensure that performance is not lost. Yin and Yang in the field even after assembly flexible to change, ferrule assembly can be over after interference detection.

2, MTP fiber optic connector ferrule float to improve transmission performance when mechanical docking. It allows two connectors under the influence of external forces make matched ferrule to maintain good physical contact.

3, MTP fiber optic connector elliptical guide pin is used in stainless steel, oval docking guide pin can improve the accuracy and reduce the wear of the guide hole, such that the optical fiber connector MTP more durable to maintain high performance transmission.

4, in the MTP fiber optic connector has a metal clip for fixing the push pin ring. Specific features:

Prevent the loss of the guide pin;

Concentrated pressure generated by the spring;

Prevent the spring from touching the fiber friction in the mechanical expansion process caused damage to the optical fiber;

5, MTP fiber optic connector spring design maximizes ribbon clearance 12 core and multi-core optical fiber ribbon applications to prevent damage.

6, MTP fiber optic connector having at least four standard matching parts, can be adapted to different types of cable, more practical, including:

Round cable loose tube structure;

Oval coat of ribbon cable;

Strip bare fiber;

Short tail cuff connector parts, very suitable for use in a small space, reduction of 45% of the volume.

Select SFF small fiber optic connector of a few tricks

In the mature markets, the clear winner with excellent technology, and also to promote the continuous development of competing technologies. In the optical fiber interconnection market, this situation will appear in a small form factor optical connectors in the field. Over the past three decades, many of the optical connector blossom, as short-lived, and LC and MTP * / MPO interconnection system will emerge as the clear leader in the global scope enables users, system designers and The optical component and transceiver designers become beneficiaries.

LC connector can provide optimal performance and ease of use on ceramic sleeve connector. MTP / MPO interconnect interface between the optical properties of the fiber port concentration to make a certain balance with optimal density. Although the original SC connectors for low-density patch panels and light modules, FC connector is designed for a more robust environment test equipment. In most applications, in view of the obvious advantages LC and MTP / MPO connector, the amount of ST, SC and FC connector is declining.

LC fiber optic interconnect system can support a variety of diameters, strain relief boots or limit benders. LC tab can help to achieve maximum density patch panel, while maintaining the ease of use. For single-mode applications, APC (angle polish) version to help achieve excellent back reflection performance. LC connector optional six rotating bushing tuning, when needed to provide the lowest insertion loss performance.

Despite the need for more high fiber density, the solution is usually based on the requirements of the transition from the ceramic sleeve is connected directly to the Precision Mold, MT-based multi-fiber connector ferrule. This makes the situation increasingly complex. Now let's step back and explain terms:

● MT Barrel - Precision Mold casing can support 2-72 fiber, used as MTP / MPO fiber optic connector on the device

● guide pin - pin hole MT sleeve utilized a part of the organization, can provide precise function of the plurality of optical fibers between two paired MT casing

● MPO connector - Rectangular industry standard multi-fiber push-pull connector interface, the public side (with guide pins) / female side (no guide pin) configuration can accommodate MT casing

● MTP connector - The optical and mechanical properties and vendor-specific versions of the MPO as a trademark connector interface, especially after pairing with optical module can be improved optical interface

According to the number of rays and specific applications, MTP / MPO interface supports both multimode and single-mode optical fiber having different numbers of optical fiber, optical cable construction and the cable diameter. The optical performance of the interface from the MT ferrule Precision Mold technology and polishing of glass fiber, these two processes in the past few years have been a large degree of improvement. Singlemode MT angle polished casing through improved return loss performance, multimode sleeve is through PC (plane) polished. For specific optical modules MTP / MPO, such as QSFP (eight functional fiber, four central fiber is not used) or CXP (24 fibers), there are a series of standards to promote the growth of the number of optical fibers. The new standard will be 16 and 32 to make the definition of fiber optic version.

Compared with the connector based on LC ceramic sleeve, MTP / MPO fiber optic technology at the level of the number of ports per significantly improved density. However, this requires designers, installers and end users to manage fiber careful assessment, so that during the life of the cable infrastructure of moves, adds and changes.
