Cisco has also upgraded its Network Conversion System (NCS) with a 1RU, 800GE line card offering 12.8T capacity, with 32 OSFP-based ports for 100GE, 400GE, and 800GE clients and 800ZR/ZR+ WDM trunks. The NCS 1014  doubles the density of previous-generation NCS versions and now includes MACsec encryption (IEEE 802.1AE) to secure point-to-point links with hardware-based encryption, data integrity, and authentication for Ethernet traffic, Ghioni stated. It supports enhanced capacity and performance with C&L-band support and NCS 1014 systems with the 2.4T WDM line card based on the Coherent Interconnect Module 8 and now supports 800 GE clients, which can be mapped directly to a wavelength or inverse multiplexed across two wavelengths to maximize reach, Ghioni wrote. 

In the pluggable optic arena, Cisco is now offering a Quad Small Form Factor Pluggable Double Density (QSFP-DD) Pluggable Protection Switch Module that can monitor the optical link and switch traffic if it detects a fault in less than 50 milliseconds. The module occupies a quarter of the rack space compared to traditional protection devices—offering 90% rack space saving over available options, Ghioni wrote.  It is aimed at Metro and DCI network customers where sub-50 ms failure recovery is essential and data centers needing fiber protection without bulky hardware, Ghioni stated. 

Cisco also added its Acacia developed Bright QSFP28 100ZR 0 dBm coherent optical pluggable in a standard QSFP28 form factor.  It is aimed at edge, access, enterprise, and campus network deployment.

Cisco has been actively growing its optical portfolio  recently adding the Cisco Silicon One G300, which powers 102.4T N9000 and Cisco 8000 systems, as well as advanced 1.6T OSFP optics and 800G Linear Pluggable Optics.
