Network device with integrated optical line system

Embodiments of the present disclosure include a pluggable optical line system module for amplification, multiplexing, and demultiplexing of coherent optical signals that can be integrated with a switch-router. Integration may include mechanical, electrical, and software control aspects. One example embodiment of the optical line system is in an industry standard small form factor pluggable module such as OSFP (octal small form factor pluggable) or QSFP (quad small form factor pluggable). When configured in a switch-router, the pluggable optical line is powered, managed and controlled by the switch-router which greatly reduces the cost, space, power and the management complexity of optical line systems.
