Some FAQs About OM4 FiberThe explosion in demand for bandwidth in enterprise networks is driving an urgentneed for higher Ethernet network speeds. Several factors are contributing to this,including broadband penetration fueled by video-rich content, Data Center demands,and exponential growth in supercomputer and R&D computing activities.

Laser-optimized multimode fiber is recognized as the medium of choice to supportthese high-speed data networks. With next-generation 40 and 100 Gigabit Ethernetspeeds on the horizon, the industry is developing a new type of multimode fiber,called OM4, which will offer a minimum effective modal bandwidth of 4700 MHzkm at 850 nm, compared with 2000 MHz-km for OM3.

What is “OM4” fiber?

OM4 fiber is a 50 μm laser-optimized fiber with extended bandwidth. It will be usedto enhance the system cost benefits enabled by 850 nm VCSELs for existing 1 and 10Gb/s applications as well as future 40 and 100 Gb/s systems.

OM4 fiber will support Ethernet, Fibre Channel, and OIF applications, allowingextended reach upwards of 550 meters at 10 Gb/s for ultra long building backbonesand medium length campus backbones. With an Effective Modal Bandwidth (EMB,also known as laser bandwidth) of 4700 MHz-km(more than double the IEEErequirement for 10 Gb/s 300 meter support), OM4 fiber is also especially well suitedfor shorter reach data center and high performance computing applications.

Why is it called OM4?

Multimode fibers are identified by the OM (“optical mode”) designation as outlined inthe ISO/IEC 11801 standard:

OM1, for fiber with 200/500 MHz-km overfilled launch (OFL) bandwidth at 850/1300nm (typically 62.5/125 μm fiber)

OM2, for fiber with 500/500 MHz-km OFL bandwidth at 850/1300 nm (typically 50/125μm fiber)

OM3, for laser-optimized 50 μm fiber having 2000 MHz-km effective modal bandwidth(laser bandwidth), designed for 10 Gb/s transmission.

Today, this evolution continues with the development of OM4 fiber as the industryprepares itself for speeds of 40 and 100 Gb/s.

What role will OM4 fiber play in next-generation speeds?

IEEE continues to work on standards for next-generation speeds, where OM4 fiber islikely to play a large role. For short reach 40 Gb/s and 100 Gb/s applications onmultimode fiber, it appears the IEEE 802.3ba Task Force has defined a PhysicalMedium Dependent (PMD) solution involving already-proven parallel opticstechnology. This will help preserve the low-cost advantage of today’s 850 nm VCSELlight sources. These parallel systems will transmit one 10 Gb/s signal on each of 4 or10 fibers (for 40 Gb/s and 100 Gb/s, respectively). Each 10Gb/s signal will beaggregated in an arrayed transceiver containing 4, or 10, VCSELs and detectors.
