small data center typical topology of a backbone to the terminal equipment to install a low number of core from the MDA, such as: equipment with line region in the server and storage devices. Addition, an optional program in addition to the use of plug and play modules and trunk cable MPO connector with needle ITM can also be used to match the plug and play modules.
in large data centers, in the ZDA installed the ITM, the insertion loss of 2.6 db. In a traditional application, an extension of the trunk cable and the use of modules instead of the ITM,
burberry soldes, the insertion loss will increase to 3.35 dB (not including the fiber loss). Visible, the ITM program led to the loss compared to the traditional program to reduce the 0.75 db.
in large data centers , ITM can be installed on the rack, trunk fiber optic cable received ZDA by the MPO connector with a pin connecting the backbone of MDA. Once the backbone fiber optic cable is successfully installed, the remaining redundant fiber optic cable will be stored in the tray of ITM.
TM installed in a rack in a small data center, integrated backbone fiber optic cable pulled MDA, without the needle The MPO connector to install plug and play modules. Once the backbone fiber optic cable is successfully installed, the remaining redundant fiber optic cable can be stored in the tray of ITM.
over the trunk and module integration can reduce an MPO connector, resulting in the decline of the insertion loss . This allows system designers to be able to enjoy the pre-termination benefits and flexibility of a modular solution, and the insertion loss decreased, so they will have more choices in the design of the network. Shown in Figure 4 or Figure 5.
in large data centers, a typical topology including installed from the main distribution area (MDA), a high core number of backbone fiber optic cable to a zone distribution area (ZDA). In the ZDA, the extension of the backbone fiber optic cable, branch jumpers and multi-core jumper and so on for terminal connections, such as: equipment distribution area (EDA),
franklin marshall, server or storage device. In addition to these products in the ZDA to EDA's connection, and can also use the integrated trunk module with with needle MPO connector.
in a small data center, integrated trunk modules, including MPO connector needle was placed in the equipment distribution area rack.

by Figure II and Figure 3 can be seen:
in a small data center, if an ITM direct match to the Plug and Play module, the insertion loss of 1.8 dB. In a traditional application, if a trunk cable and the use of two modules instead of ITM and a single module, the insertion loss will increase to 2.6 dB (not including the fiber loss). Visible, the ITM program led to the loss compared to the traditional program to reduce the 0.8 db.
like the premise of
unable or unwilling to deal with the trunk fiber optic delivery or redundant data center administrators, and perhaps a commonly used approach is the inventory module and not yet terminated fiber optic cable in the specific construction site of the MPO connector termination. In recent years, with the advent of do not need resin without grinding the MPO connector, for data center requires a lot of trunk cable,
abercrombie france, no complicated advance planning,
burberry, measurement and calculation of MPO connector field termination in the data center has become increasingly attractive.
data center design and management staff are also faced with the question of the link insertion loss. With the increase of the speed of the network can be accepted by users maximum insertion loss values are declining. Gigabit multimode OM3 fiber-based Gigabit Ethernet system permitted by the insertion loss is also very strict, in order to achieve the best long-distance transmission capacity.
; at ITM, the rotation of the sliding tray design will be able to more easily configure the trunk fiber optic cable, which are the backbone fiber optic cable have been pre-terminated MPO connector with needle or without needle. Once the backbone fiber optic cable installation to the end of the excess fiber optic cable will be stored in a sliding tray in order to avoid too much redundancy.
data center performance and flexibility for the diverse needs, but also rich in the market opportunities for a variety of new routing scheme. A good value-added solution of choice is the integration of fiber optic module ITM integrated the trunk module), you can cope with more and more challenging data center cabling needs.
North American data center market is continuous growth and development: the data centers of various sizes have sprung up showing a strong growth; each data center, regardless of size are convenient, flexible, pre-terminated, modular, structured cabling products and programs growing demand.
before the core number and length of trunk cable,
christian louboutin, fiber optic cable manufacturers or distributors have tried to stock a certain number of the factory pre-terminated trunk cables to solve the delivery problem. Although this countermeasure may be able to solve the on-time delivery problems, but it often may deepen the fiber optic redundant administrative burden. For example: In the case of a very tight delivery, data center managers can only order an inventory of up to 100 ft pre-terminated trunk cables, but in fact, they need only 80 feet long, therefore, the administrator shall racking their brains to find a way to manage the excess of 20 feet of the trunk cable.

the
; the ITM integrated backbone fiber optic cable is generally 40 or 80 feet long, all redundant fiber optic cable can be stored in the tray. Ordering inventory, to ensure that an emergency use, very convenient to the management and maintenance of the data center.
the
the ITM product's main features is a module set aside a certain length of 12 core data center backbone fiber optic cable (see figure ). In the data center, with ITM products, you do not need to link time-consuming pre-planning, measurement and calculation, it is because the ITM reserved data center backbone cable, will help create a redundancy of any fiber optic cable link; In addition,
ray ban, the trunk cable and module integration, but also can reduce an MPO connector thereby help to reduce the insertion loss; fiber of the ITM its modular fast connectivity solutions for data center design another faster and more convenient idea.
Overall, the use of ITM can provide many benefits, including:
redundant fiber optic cable ;
• shorten the delivery time;
• reduce the number of parts needed in the integrated wiring;
• reduce the insertion loss;
when it comes to pre-termination and data center managers, modular solution, the two problems often occur: Delivery time and redundancy management.
in a large data centers contain the zone distribution area (ZDA),
lunettes ray ban, set dry modules, including MPO connector with a pin and placed in a rack of equipment distribution area. From there,
casque beats, the trunk will be pulled ZDA with a needle connected to the connector.
Introduction: North American data center market is constantly growing and development: the data centers of various sizes have mushroomed to show strong growth; each data center, regardless of size, are convenient, flexible, pre-terminated, modular, structured cabling products and the growing demand of the program. The keyword Corning Cable data center integration module the solution
the ITM be applied to small data centers (with emphasis on cross-Internet) or large data centers (with emphasis regional distribution). Figure II and III.
