From Silicon Labs
As both business and residential customers demand greater access to high-speed network services, equipment suppliers are searching for ways to provide lost cost, multi-protocol interfaces that can be quickly provisioned for use. A prime example of this trend is the convergence of various data rates in the vicinity of 10 Gbps that can all share much of the same hardware and optics, even though each is governed by a different protocol as listed below in Table 1. At the same time as performance and flexibility requirements of network interfaces are increasing, the expected levels of quality are also increasing, creating a need for more sophisticated and efficient test techniques to guarantee not only hardware functionality but design margin against the effects of aging, temperature variations, system noise and incoming signal degradation.
