OM4 multimode fiber optimized for short wavelength division multiplexing (SWDM) applications


LaserWave WideBand Multimode Fiber is a 50 micron (µm) laser-optimized multimode fiber designed to help meet the demanding requirements of today’s OM4 networks, as well as next-generation, short wavelength division multiplexing (SWDM) applications.

This wideband fiber extends the ability of conventional OM4 multimode fiber to support multiple wavelengths using SWDM. Unlike traditional multimode fiber, OFS LaserWave WideBand Fiber is designed to support traffic over a range of wavelengths from 846 nm to 953 nm. This capability allows multiple lanes of traffic over the same strand of fiber, helping to significantly improve the bandwidth capacity of mujltimode fiber while also maintaining its cost advantages for short-distance applications, up to 300 meters or more.

Product Description

Building on the history of LaserWave FLEX 550 (OM4) Fiber, LaserWave WideBand Fiber meets current OM4 requirements while also supporting CWDM applications from 850 to 950 nm. This fiber supports planned four wavelength 100 Gb/s applications, while providing future proofing for tomorrow’s 400 Gb/s and higher speeds.

LaserWave WideBand Fiber offers low bending loss throughout the entire operating window, while maintaining excellent long-term fiber strength and reliability.

  • Designed for SWDM applications (850 nm to 950 nm)
  • Uses SWDM to increase transmission capacity by up to 400%
  • Complies with OM4 fiber requirements and is backward compatible with existing OM4 networks and applications
  • Manufactured using the industry’s tightest geometric control
  • Supports today’s applications including 100 Gb/s Ethernet and 32 GFC
  • Ready for next-generation wideband networks
  • Duplex transmission of 100 Gb/s using SWDM technology
  • Supports 400 Gb/s transmission over 8-fiber links
