Optical Signal-Conditioning Enables Coherent Module Testing

Today's network bandwidth demand is being enabled by advanced DSP engines. Increasing deployed bandwidth is accomplished through two factors; a pure baud rate / data rate increase per channel and an adaptability to accommodate many different and changing network topologies.  To enable the flexibility required in todays network, these DSP’s not only adapt in real time to a wide range of network impairments (i.e. loss, noise, distance, dispersion), but also report the values they are compensating for.  This dramatically simplifies network planning and monitoring.
