LazrSPEED® OM5 WideBand Multimode Fiber (WBMMF)

To meet the challenges associated with escalating data rates and the ongoing need to build cost-effective infrastructure that can support bandwidth needs today and in the future, CommScope has developed LazrSPEED® OM5 WideBand Multimode Fiber (WBMMF) cabling solutions, which enhance the ability of short-wavelength division multiplexing (SWDM) technology to provide at least a four-fold increase in usable bandwidth. OM5 maintains compatibility with OM3 and OM4 fibers and supports all legacy multimode applications.

LazrSPEED OM5 WBMMF expands the specified high-bandwidth operating wavelength spectrum from a single wavelength at 850 nm to a range of more than 100 nm that includes 850 nm through 950 nm. This wide specification range enhances SWDM technology’s capability to transmit 40G and 100G over a single pair of fibers and to drastically increase the capacity of parallel-fiber infrastructure, opening the door to four-pair 400GE and terabit applications.


OM5 and OM3/OM4 Comparison


OM5 WideBand Multimode Fiber Bandwidth Comparison Chart, om5 fiber, wide band, om5   

  • Total bandwidth is the result of combining modal bandwidth and chromatic bandwidth.
  • Two grades of  laser-optimized MMF are widely used today:
    • OM3 is specified at 850 nm,
    • OM4 delivers higher bandwidth than OM3 at 850 nm.
  • LazrSPEED OM5 WideBand extends the capability of OM4 across enough spectrum to support at least four low-cost multiplexed wavelengths.

Features and Benefits of SWDM and LazrSPEED OM5 WideBand Solution:

  • Retains legacy application support of OM4
  • Increases capacity to > 100G per fiber
  • Enables single-pair Ethernet at 40G and 100G
  • Enables single-pair Fibre Channel at 128G
  • Reduces parallel fiber count by factor of 4
  • Extends MMF utility as universal medium
  • Matches footprint of InstaPATCH 360DM module
  • Fits the UD and HD fiber shelves, as well as existing 360G2 and UHD shelves
