SP8800 Lesson 5 Part 2 Slide 2

Let's now review fiber design with respect to the Data Center.

SP8800 Lesson 5 Part 2 Slide 3Copper design is fairly straight forward, as it is limited to the 100m channel, has a standard connector type, will predominantly be used in the horizontal, is likely only to be of one performance specification, and supports a single network type. Namely, Ethernet. Fiber design can be more complex as there are legacy connectors and interfaces, multiple performance demands, used from the EDA to HDAto MDA and Entrance and multiple networks. The design process phases should include: A. Calculate fiber requirements per cabinet. Also allowing for growth and redundancy. B. Determine the cable routes from each cabinet to each cabinet and each area to each area, including EDA to HDA, HDA to MDA, and MDA to Primary Entrance. In addition, consider any secondary or tie cable routes. Wiring standardslimit the distance between the main cross-connect and closet. Distances may impact your choice of glass and application interface. C. Determine interconnect and cross-connect at each termination point, and any required splicing points. D. Determine the supporting structures required for additional lateral cable runs. Each of these key phases will require additional design considerations that wewill now cover.

SP8800 Lesson 5 Part 2 Slide 4

TIA/EIA942 notes that the horizontal media distance shall be a maximum of 90m link and 100m channel, independent of media type. See item (2) above. The maximum cabling distance in a Data Center not containing an HDA shall be 300m, including cords, for fiber. But, coppermedia is of course still limited to a 90m link and a 100m channel. See area (1) above. Backbone Media (3) can, again, be copper or fiber. Copper is limited by the same 90/100m maximum distances, Fiber is limited by application and fiber media choice - the standard offering some 'informative' distances. ISO/IEC IS24764 - requires similar distances between EO and ZD (HDA) but offers more specificguidance for fiber applications that maybe running between the ZD and MD or MD and ENI. This guidance does include some information relating to fiber 'type' (OM1, OM2, OM3 etc.), and includes connector and splice adjustments. But, it is only based on minimum standards performance for fibers, connectors, and splices.

So TIA and ISO provide some application distance guidance but only for 'minimum' standards based products. SYSTIMAX fiber products meet and exceed by some margin the standards based worst case allowances. Therefore, significant design benefits can prevail. Additional distance, connectors and splices are allowed, providing the power budget of the application is notexceeded and bandwidth is taken into account. Therefore, designs will need to consider the following steps: 1. Current and future applications to be supported, 2. Distances between interfaces, 3. Fiber bandwidth/performance, 4. Attenuation of cable and components, 5.Administration requirements - SC, LC, or MPO, simplex or duplex.

SP8800 Lesson 5 Part 2 Slide 6

The SYSTIMAX Performance Specifications, Volume One, Applications, is an invaluable tool in channel fiber design. As you cannot calculate the impact of, or measure, bandwidth in the field, this guide will tell you distances that applications are supported and warranted. It takes into account the impact of bandwidth on given performance glass and allows...
