Upgrading fiber. Which one to choose?

Q. We are upgrading a network at a brownfield site where most fiber runs are close to 100 meters, and we’re considering an upgrade from OM2 to either OM4 or single-mode. Which one should we choose?

A. Customers prefer to stay with multimode, as the transceivers are generally cheaper. If your runs are 100 meters or less, OM4 would allow you to migrate to 400 Gb/s in the future, based on the draft requirements of IEEE 802.3cm. If your runs are over 100 meters, there are proprietary transceivers that would allow you to go farther at 100 Gb/s on OM4, but at this stage you should be looking at single-mode.
