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.
Cisco NCS 1010 is a 3RU chassis that has an in-built External Interface Timing Unit (EITU) and the following field-replaceable modules.
-
Controller
-
Two power supply units
-
Two fan trays
-
Fan filter
