What Has Changed Since 62.5 Micron Was Standardized? Data rate requirements exceeds capabilities of LEDs Numerical aperture no longer critical LED output power and align improves Connector alignment and polishing improves Short wavelength VCSELs are introduced and are the future for high-speed applications Fibre Channel 622 Mbps ATM 1 Gbps Ethernet/1.2 Gbps ATM SM Lasers and connector still not cost-competitive Gigabit VCSEL 1/3rd the price of LW laser Could equate to $1000 plus premium to the customer Requires use of special launch cord with MM fibers 9
LED vs. VCSEL vs. Edge-Emitting Laser 10
50 µm Cable Support for Existing Standards Maximum power penalty with LEDs - 4.7 db Long Wavelength LED Applications FDDI, Fast Ethernet, and 155 Mbps ATM Power budget supports full 2 km distance Short Wavelength LED Applications 10Mbps Ethernet and 4/16 Mbps TR Specifications do not support full 2 km distance However three leading suppliers of transceivers exceed power specifications Testing indicates support for 2 km distance Uses the same electronics and connectors 11
The Facts On 1 Gbps Optical Fiber Systems The installed base of fiber is optimized for use with LEDs Most combinations of laser sources and multimode fiber produce superior performance. Some combinations of multimode fiber and laser sources produce poorer than expected performance. Examples of poor performance have been verified with 62.5 µm fiber and singlemode lasers. No examples of poor performance of 50 µm fiber have been found. 50 µm fiber cable is typically 10 to 15% less expensive. 12

Improving Fibers Substantial improvements to performance of multimode fiber used with lasers can be achieved by establishing clearly defined launch conditions For measuring bandwidth For characterizing sources This improvement takes advantage of the knowledge of the difference in launch condition between LEDs and Lasers 14
FO-2.2 Task Group Scope Develop a recommendation for laser-based system bandwidth prediction methodology For short haul data communications Using both 62.5 µm fiber and 50 µm multimode fiber Focus on 850 nm window sources (e.g. VCSEL and CD laser technology) Determine if a specifiable launch condition exists To provide a better agreement between fiber bandwidth characterization and actual laser transmitter performance Develop a recommendation for test methods as appropriate 15
Objectives Devise a bandwidth test for fiber which is representative of the actual system performance Standard overfilled bandwidth does not correlate to laser bandwidth Develop transceiver launch distribution test to ensure restricted transmitter launch (e.g. encircled flux) Typical transceivers range from overfilled to singlemode 16

So-called High-Performance 62.5 Micron Beware of distance claims made by so-called highperformance 62.5 micron cable suppliers No guarantees when you exceed the recommendations established by IEEE Complex relationship between attenuation and bandwidth Vendors making claims based on typicals versus worstcase requirement Competitive pricing information indicates that Highperformance 62.5 micron : 25% to 30% premium over standard-grade 62.5 micron 30% to 40% premium over standard-grade 50 micron 19
TIA-568-B.3 Optical Fiber Connector Horizontal optical fibers at the work area outlet shall be terminated to an optical fiber outlet/connector meeting the requirements of ANSI/TIA/EIA-568-B.3. To facilitate inter-office moves, consider use of one style of duplex connector for the work area outlet. The 568SC connector was previously specified by ANSI/TIA/EIA- 568-A and should continue to be considered for the work area outlet. Other connector styles, including those of a small form factor, may also be considered. 20
TIA-568-B.3 Optical Fiber Connector Duplex connector designs shall be used in the main cross-connect, intermediate cross-connect, horizontal cross-connect, and the consolidation point, provided that the connector design satisfies the performance requirements specified within Annex A. These connector designs shall meet the requirements of the applicable TIA Fiber Optic Connector Intermateability Standard (FOCIS) document. 21
Gigabit Ethernet on Fiber 1000BASE-SX Uses low cost short wavelength (850nm) VCSEL light source Designed for use on multimode fiber Targeted at short backbones and horizontal 1000BASE-LX Uses conventional laser light source operating at long wavelength (1300nm) Designed for use on singlemode fiber or on multimode fiber with mode-conditioning patch cords. Targeted at longer building backbones on multimode and campus on single mode. 22

Cabling for 1000BASE-SX and 1000BASE-LX Conclusions 1000BASE-SX is the preferred technology for links within buildings due to the lower cost transceivers. Maximum operating distances using multimode fiber are constrained by fiber bandwidth. When using 1000BASE-SX much greater distances are possible with 50 micron than with 62.5 micron fiber. 50 micron fiber is less expensive than 62.5 micron fiber. 50 micron fiber is already an option in ISO/IEC 11801 and it will be included as an option in the forthcoming TIA/EIA-568-B. 24

Objectives - Next Generation MMF Cabling Support lowest cost/complexity system solution Support legacy LAN applications Remain friendly for cable manufacturer and installer Provide migration path to at least 10 Gbps with achievable technology Meet the needs of in-building network applications with a single universal medium 27
What is Lowest Cost @ 10 Gbps? Transceiver Serial Transmission (no WDM) Direct Modulation (no external modulators) Uncooled and unisolated lasers (no extra components) 850-nm VCSELs (low-cost surface emitting laser) Multimode specific solution (no SMF tolerances) Media Two-fiber system Multimode Fiber Cable (single universal media) 28
10 Gb/s Support with Achievable Technology 10 Gb/s 850 nm VCSELs exist today Bandwidth is the most critical fiber parameter Modeling and experiments prove MMF can support 850 nm VCSELs at 10Gb/s to 300 m Production yield of high BW MMF will determine media cost Must select highest BW design that meets all previous objectives 29

10 Gb/s Support Conclusions Historical trends show emerging 850 nm VCSELs will provide the lowest cost migration path 1300 nm devices historically required to also support SMF and bear associated costs Need MMF with sufficient bandwidth that meets all other objectives 50 µm fiber has the highest bandwidth potential while meeting all other objectives Capable of supporting 10 Gb/s serial transmission at either 850 or 1300 nm 31
IEEE 802.3ae (HIGH SPEED STUDY GROUP) Working to Develop Next Higher Data Rate Probably 10 Gb/s How Will 10 Gigabit Be Defined? How Will 10 Gigabit Be Obtained? Source Type Number of Sources Wavelength(s) Media Requirements SM MM ( Next Gen ) 17 Proposals Currently 32
Proposal Too Early to Take to the BANK! Add a new 50 µm performance level in addition to existing 50 µm specification Bandwidth: 500/500 MHz-km at 850/1300 nm with over-filled launch 2200/500 MHz-km at 850/1300 nm with laser launch* Attenuation: 3.5/1.5 db/km at 850/1300 nm Singlemode cable specifications unchanged SM connector return loss under investigation * The laser launch bandwidth measurement, which is not yet defined, must account for the mode power distributions that occur within the fiber due to the effects of source characteristics and transverse offsets in connections. IEEE High-Speed Study Group must determine electronic set. 33
Beyond 10 Gb/s Data rates above 10 Gb/s can be supported Serial Transmission ~35 Gb/s @ 100 m with serial transmission WDM multiplies supportable rate by number of wavelengths used example: 4x10 Gb/s @ 300m Multi-Level Coding increases bandwidth efficiency (multiple bits per baud) 34
