  • Channel 0 Center Wavelength: 191.3 GHz
  • Channel 96 Center Wavelength: 196.1 GHz
  • Total Number of Slices: 388
The flex spectrum feature of this hardware is particularly notable, offering a slice width of 12.5 GHz and enabling up to 388 slices. This flexibility allows for a minimum settable channel bandwidth of 25 GHz (equivalent to 2 slices) and can be extended up to a maximum of 4850 GHz (388 slices), catering to various bandwidth needs across different network scenarios. Optical port isolation is another key specification, with 28 dB isolation for 0 to 15 dB attenuation and 25 dB for 15 to 25 dB attenuation, ensuring signal integrity and reducing interference. The NCS2K-20-SMRFS is designed with efficiency in mind, featuring a minimum insertion loss of 6 dB and a Variable Optical Attenuator (VOA) dynamic range of 15 dB, operational for precise attenuation control. The VOA attenuation setting accuracy is within +/-0.5 dB for 0 to 15 dB attenuation and +/-1 dB for 15 to 25 dB attenuation, ensuring precise signal management. Each channel can handle a maximum input power of 15 dB, with a maximum polarization dependent loss of 0.5 dB, maintaining signal quality and consistency. From a power perspective, the device operates typically at 60 W, with a maximum power consumption of 84 W, and is designed to fit into a single slot for efficient space utilization. The card LEDs provide visual indications of operational status, including failure (FAIL), active/standby (ACT/STBY), and signal fail (SF), facilitating easy monitoring and maintenance. The operational environment specifications indicate a minimum normal operating temperature of -5 °C and a maximum of 55 °C. It can function within a relative humidity range of 5% to 95%, ensuring reliable performance across various environmental conditions. In summary, the CISCO NCS2K-20-SMRFS is an advanced optical networking device that combines flexibility, efficiency, and high performance, making it suitable for a wide range of networking applications. Its comprehensive hardware specifications and capabilities ensure it can meet the demands of modern optical networks, providing scalable, reliable solutions for complex networking challenges.
