Due to the increasing demands on technology and capacity, the number of network connections in a Data Center is continually increasing. Irrespective of the connection type, the highest possible port density supported by a scalable, modular cabling system is a critical requirement of the modern Data Center.

The AMP NETCONNECT Data Center Cabling Systems provide those key features which traditional cabling systems cannot offer. Connectors that are terminated and tested in the factory, enable you to deploy real "Plug&Go" solutions. Pre-terminated highpair/ high-fiber cable assemblies which connect to modular breakout cassettes give flexible and fast deployment of Copper and Fiber Optic solutions within the Data Center.

The core of the MPO Fiber Optic Cabling System is the MTFerrule. This precision component allows 12 fibers to be housed within a single connector that is half the size of an SC connector. Therefore, you can connect 12 fiber links simultaneously – each capable of 10 Gb/s.

The MRJ21 Copper Cabling System is designed with similar functionality, terminates 24 twisted pairs in a compact 48 pin connector. Therefore, one MRJ21 link can support 6 x Gigabit Ethernet ports or 12 x Fast Ethernet ports, depending on the performance requirement.

Once installed, these systems provide easier on-going management and are more cost-effective over the life-time of the installation compared with traditional cabling systems.

The MPO system is an excellent choice for many fiber applications. Modular components are the key to fast deployment, simple installation, capital effectiveness and network flexibility. Pre-terminated trunk cables, breakout cassettes and cable assemblies are the basic modular components needed for a complete network.

Increasing Density Whilst Reducing Power Consumption
In line with the desire of organizations to provide more performance in less space within their Data Center environment whilst meeting power consumption objectives, AMP NETCONNECT has realized the need to develop focused product sets for these environments that meet the design objectives of guaranteed high density performance, seamless migration and user flexibility at a reduced power level. This provides some advantages:

• Better airflow in racks and raised floors
• Less power consumption
• Allows cost efficient cold and warm areas

Using smart cabling to improve spaces and airflows, active cooling can be focused on the areas where high heat dissipation is require and not be wasted on cooling traditional passive cable systems. Using pre-terminated systems has the additional advantage of flexibility, being able to allow adds, moves and changes within minutes.
