Juniper Simplifies DCI with Innovative Coherent DWDM Line Card

Over two decades ago, when a friend of mine visited his parents in a remote countryside village in China, he had to first take train from Beijing to the provincial capital, then take a crowded coach on bumpy country roads to the county’s capital, next take passenger ship, and finally walk dozens of miles on the mountainous road to his parents’ village.

LLDP Extension for Optimal End-to-End Optical Network Performance

LLDP Extension for Optimal End-to-End Optical Network Performance

In a linear optical network that contains multiple optical nodes, it is an operational goal to optimize the end-to-end optical network performance, measured by the receiving node’s optical BER (Bit Error Rate). And as time goes on, the receiving node’s BER can drift, due to factors such as the sending node’s transmitting optical power drifting, ambient temperature variation, equipment aging, etc. While some factors are difficult to control, such as ambient temperature variation and equipment aging, the sending node’s transmitting optical power is easily controllable and can be adjusted to compensate for the BER drifting due to other factors. So if we can continuously monitor the receiving node’s real-time BER, provide feedback to the sending node, and adjust the sending node’s transmitting optical power as needed, we can obtain the optimal end-to-end optical network performance.
