Cisco NCS 1010 chassis and line cards

Cisco NCS 1010 is a next-generation optical line system optimized for ZR/ZR+ WDM router interfaces. Its salient features are:

• Provides point-to-point connectivity between routers with WDM interfaces.

• Multiplexes the signals received from multiple routers over a single fiber.

• With one MPO port, it can be scaled to 8 Degree.

• Caters to C-band WDM transmission to maximize capacity, and can be enhanced to C+L combined band in the future.
