Optical Cabling Infrastructure for Data Centers

• The most efficient optical cabling solution is one in which all components are pre-terminated and tested in the factory prior to installation.

• This “Ribbon Array” or “Plug & Play” type solution utilizing pre-connectorized cable assemblies, trunks and components is the fastest and most reliable method for bringing a system up and running.

Open Rack or Cabinet Considerations

• Cable Management• Security• Cable Entry• Cooling• Layout / Size• Safety• Appearance• Hardware Mounting

CABINETS• Cabinet should have Integrated Cable Management as a

integral part of the design.• Cabinet should be Scalable and Modular in Scope to

Accommodate Growth as cabinets are ganged together.• Ease of Cabling Reconfigurations, Moves, Adds, and Changes

(MAC)• Facilitates Hardware Migration such as Switches Above the

Raised Floor Environment.• Integrated Cabling Paths; Horizontal, Vertical, Lateral, and

CENTRAL NETWORK POINT OF ADMINISTRATION CONFIGURED WITH PATCH PANELS AND HARDWARE

The DC Cabinet Provides

Example of Mounting hardware in the same central network point of administration which will improve light loss budget, reduce trunk cabling expense, facilities ease of above the floor configuration

cabling changes while maximizing floor space

PATCH PANELS…………..

Patch Panels• Extremely Organized

Infrastructure Above The Floor Changes

• Manageable Cable Reconfigurations

• Efficient Air Flow Due to Less Cabling Under the Floor

• Ease of Moves, Adds and Changes Reducing Down-time

Patch Panels

• Scalable For Future Growth and Alterations

• Multi-platform Use Within One Central Location

• Promotes Return On Investment (ROI) On Cabling Infrastructure

Modular Design allows for growth as needed and flexibility for future connectivity

Patch Panels

• Flexible, Scalable and Upgradeable• Simplifies Multi-floor Connectivity within

Panel• Back Bone Infrastructure Pre-installed and

Re-useable• No Need to Re-cable at Existing

Equipment Port Interface Level thus Saving or Preventing Interface Outages

Patch Panel Options

OPTIONAL PLATES FRONT ACCESS

Example of front access Patch Panel

Design of front access patch panels allows for placement of panels in the front and back in the same bay. This gives you the capability to place your patch panels back to back therefore doubling your channels in half the floor space

Front Access Patch Panels give you the ability to have up to 2048 channels per Bay.

A combination of Vertical, Horizontal and above the floor front to back pass thru cable access ports result in the desired Cable Management ability to Handle the High Density.Solutions

Ribbon Array Technology Advantages Over Current Technology Cabling Schemes

• Elimination of cable slack management problems normally associated with high fiber count connectivity under the raised floor data center environment at the Director, CPU, and Central Network Point of Administration (main area cabinet and patch panel locations)

• Trunk cables configured with ribbon array connectivity can be extended in length by simply attaching couplers to another trunk; this will result in substantial time and monetary savingsfor future installs, moves, adds, and changes

• Patch panels are factory pre-cabled and tested for end to end (dB) loss before being shipped to the install site which minimizes installation time

• The modular design of ribbon array trunks, multi-channel patch cords, jumpers, patch panels and cassettes, provide maximum flexibility for your cabling plant

Ribbon Array Technology Advantages Over Current Technology Cabling Schemes

♦ Equipment changes, cabling reconfigurations, or system upgrades are easily accomplished above the floor by simply unplugging and replacing the existing ribbon array cassette or patch cord to match new equipment connectorization

♦ Ribbon array loose tube trunks have a smaller diameter compared to standard trunk tight buffer cables increasing tray capacity by 33%

♦ Ribbon array trunks offer the perfect disaster recovery solution; simply unplug the damaged trunk and in minutes installation of the replacement trunk is completed

♦ Future proof the cabling infrastructure with the ability to instantly change connectivity requirements as existing hardware is upgraded or new hardware is purchased

36 Channels in six 12 Fiber MTP Ferrules

With the new 72 fiber MTP Ferrule a 1 RU patch panel now only requires oneMTP coupler which provides the benefit of cable management and reduced cost

The standard 6 position (36 channel) MTP Bracket is now 216 Channel capable

36 Channels now in one 72 Fiber MTP Ferrule

The standard 12 position ( 72 channel) MTP bracket

now has the capacity for 432 channels

Ribbon Array Technology Advantages Over Current Technology Cabling Schemes

♦ CPU’s, Directors, and patch panels can all be pre-cabled

♦ Universal point of connectivity allows for integration of Mainframes, SAN, and LAN cabling and connectivity

♦ Multiple Data Center locations can draw from the same inventory

♦ Quick cut over time frame and a reduction of outage time

♦ Save the expense of purchasing new trunk cables as small form factor connectors are introduced into the marketplace

♦ Future proof the under floor cabling infrastructure as a one time expense; only the cassettes and arrays will change as hardware changes are made, resulting in an overall lower cost as compared to current technology products, solutions, and installations

♦ Future moves, adds, and changes can be done on a same day basis; planning, cut over, and outage time can be minimized

Cabling and Cost Analysis Ribbon Array Connectivity

♦ Current technology trunk cabling systems will only retain approx. 30% of the original investment & incur additional expenses for labor and cut over time as connectivity is upgraded - Ribbon Array technology will retain up to 70% of the monetary investment originally expensed in the cabling infrastructure along with the additional benefit of savings in time and labor as connectivity upgrades are made.

♦ The above monetary time and labor savings can be realized more than once as each new connectivity scheme is introduced into thedata center environment.

♦ The over all net effect is that the ribbon array solution is less expensive. The benefits and advantages of the ribbon array technology can be realized and implemented from day oneand is easily incorporated into existing current cabling schemes.

VCSEL

• Vertical Cavity Surface Emitting Laser – Changed bandwidth and physical layer

infrastructure– Creates a smaller more focused beam

than LED at much lower cost than Laser– Used primarily with 50/125 fiber– Now available in 1310 nm for use with

dual window SM fiber

VCSEL

To briefly sum up the issue of fiber optic core sizes and their appropriate application there is only one critical common element to consider for the basis of the decision on which fiber optic core size is to be specified for the cabling infrastructure, you must match the transmitter specifications of the hardware to the grade and core size of glass manufactured that was specifically designed to match that particular wavelength and type of transmitter such as a LED, LASER or VCSEL that is the light source in the hardware that you will be installing.

In the past only LED's or LASER's sources were manufactured and you could specify 62.5/125 for any multi-mode transmitter application and 8.3/125for any single-mode transmitter additionally there was only one grade of 62.5/125glass now their are two grades of 62.5/125 glass, four grades of 50/125 glass and many application specific single-mode glass constructions. The introduction of VCSEL's as the transmitter in the hardware for Fibre Channel and SAN switch infrastructure has beenthe leading force behind the change from 62.5/125 to 50/125 fiber.
