Improved design and engineering efforts make the interface a strong asset, not a weak link. As the industry deploys 40-Gbit/sec optical networks and moves ahead to 100-Gbit/sec data rates, service providers and data center managers may question whether the multi-fiber push-on (MPO) connector can perform reliably at those speeds. They saw the first-generation MPO as […]

You can force the NIC into 100Mbit full-duplex by disabling auto-negotiation and 100Mbit half-duplex capability. Example with hme0: 1. Make […]
