Use rated multimode fiber (OM2/OM3/OM4 as applicable) and certified LC patch cables for reliable performance. Verify device compatibility and, if available, install vendor-recommended firmware or use port settings on the HPE device to ensure proper negotiation at 1 Gbps. Avoid exposing the optical interface to dust—keep protective caps on when not in use.
