Q: Just confirming the cabling requirements—can we use our existing OM3 fiber backbone, or do we strictly need OM4/OM5 for the MPO-12 interface? By L***l on 2026-01-11
A: You can definitely use your existing OM3 runs! These modules support up to 70 meters on OM3 multi-mode fiber. If you decide to upgrade to OM4 or OM5 later, you'll be able to push the transmission distance to the maximum 100 meters. Just make sure your MTP/MPO-12 patch cords are clean prior to installation!
