What distinguishes OM4 cabling from OM5 cabling?

Choose two
  • A OМ5 supports speeds up to 100 Gbps, while OM4 does not.
  • B OM5 is approved as Wide Band Multimode Fiber (WBMMF), while OM4 is not.
  • C OM4 supports distances up to 100 m. while OM5 supports distances up to 150 m using 100 GBps transceivers.
  • D OM5 supports Multiplexing operating in the 850 to 950 nm range, while OM4 does not.
Explanation

OM5 is the approved designation for Wide Band Multimode Fiber (WBMMF). It meets OM4 specifications at 850 nm and adds bandwidth characterization around 953 nm, allowing 100G BiDi or SWDM optical links to reach up to 150 m, compared with 100 m on OM4. OM4 may still be used with SWDM, although its specified wideband performance and achievable reach are lower.
