7 OM4 OM4 Approved February 2010 Modal Bandwidth (MHz.km min) Wavelength (nm) Optical fibre ISO/IEC Ed.2.2: 2010 Information technology - Generic cabling for customer premises Multimode 50/125 or 62.5/125 50/125 OM1 OM2 OM3 A1b or A1a.1 Cabled optical fibre A1a.2 IEC : /125 OM4 A1a.3 IEC : 2010

8 OM4 BS 7718: BS 7718 B.3.2 Optical fibre bandwidth B General A Code of Practice for the Installation of Fibre Optic Cabling Annex B (informative) Guidance notes The bandwidth of an optical fibre subsystem is a complex function of the fibre optic span and the transmission equipment. The optical fibre can be viewed as a transmission medium with a defined potential bandwidth. The actual bandwidth is dependent upon the transmission equipment used and may approach the potential bandwidth when narrow spectral width optical transmitters are incorporated within the transmission equipment.

9 OM4 MMF Bandwidth Measurement 2002 ISO/IEC Ed.2 EN Modal Bandwidth (MHz.km min) Over-filled launch Effective laser launch Information technology - Generic cabling for customer premises Information technology - Generic cabling systems - General requirements and office areas Wavelength (nm) Multimode 50/125 or 62.5/125 50/125 OM1 OM2 OM Effective laser launch bandwidth is assured using DMD as specified in IEC (or BS EN) ISO/IEC Ed.2 Optical fibre EN :2002 Optical fibre IEC : A1b or A1a.1 A1a.2 EN : A1b or A1a.1 A1a.2 IEC : 2004 and EN : 2007 Two equivalent parameters could be used to provide conformance to the requirements for the minimum effective modal bandwidth-length product of 2000 MHz.km. One was DMD and other was calculated effective modal bandwidth (EMB C ) Both defined the optical source as meeting the requirements of the IEEE specification for the 10GBASE-SR VCSEL.

10 OM4 MMF Bandwidth Measurement 2010 ISO/IEC Ed.2.2 Modal Bandwidth (MHz.km min) Over-filled launch Effective Wavelength (nm) Information technology - Generic cabling for customer premises Multimode 50/125 or 62.5/125 50/125 OM1 OM2 OM Modal bandwidth requirements apply to the optical fibre used to produce the relevant cabled optical fibre category and are assured by the parameters and test methods specified in IEC ISO/IEC Ed.2 Optical fibre IEC : 2010 A1b or A1a.1 A1a.2 50/125 OM A1a.3 IEC : 2010 and EN : 2010 Continues to apply the two equivalent approaches - DMD and EMB C but now makes the requirement independent of the optical source by creating a standard launch condition template. The potential confusion comes from the fact the new standard template does not provide values of 2000 MHz.km and 4700 MHz.km as shown in the table above for Categories OM3 and OM4 cabled optical fibres respectively - instead the revised EMB C limits equate to values of 1770 MHz.km and 4160 MHz.km respectively. Optical fibres meeting these requirements under the standard launch condition template are expected to provide effective modal bandwidths of 2000 MHz.km and 4700 MHz.km when used with the 850 nm VCSELs specified by IEEE for 10Gb/s.

52 EN x Series EN x Introduction EN x SERIES Data centres - Facilities and infrastructures Data centres, housing and supporting the information technology and network telecommunications equipment for data processing, data storage and data transport are required both by network operators (delivering those services to customer premises) and by enterprises within those customer premises. Data centres need to provide scalable and flexible infrastructures to easily accommodate the rapidly changing requirements of the market. In addition, energy consumption of data centres has become critical both from an environmental point of view (green house gas emission) and with respect to economical considerations (cost of energy) for the data centre operator. The implementation of data centres varies in terms of: purpose (enterprise, co-location, co-hosting or network operator facilities); physical size; accommodation (mobile, temporary and permanent constructions). This series of specifies requirements and recommendations to support the various parties involved in the design, planning, procurement, integration, installation, operation and maintenance of facilities and infrastructures within data centres. These parties include: owners, facility managers, ICT managers, project managers, main contractors; architects, building designers and builders, system and installation designers; facility and infrastructure integrators, suppliers of equipment; installers, maintainers.
