Why Choose This Product?

• Correct optics for 2T NCS 6000 fabric — Cisco specifically identifies NCS-FAB-OPT2 for 2T multi-chassis configurations, reducing the risk of substituting the wrong generation of fabric optics.
• 96-module procurement bundle — A standardized 96-module set simplifies BOM creation and large-scale fabric deployment planning.
• High-density 25G channel architecture — Twelve 25G channels per module provide the optical density required by the NCS 6000 fabric-interconnect design.
• Purpose-built fabric connectivity — These are dedicated CXP2 fabric-interconnect modules rather than generic Ethernet optics, making application matching straightforward.
• Diagnostic visibility — I2C management and optical-power diagnostics provide useful visibility when troubleshooting high-density fabric links. 
• Supports 2T architecture upgrades — The SKU is directly identified in Cisco's NCS 6000 documentation for 2T multi-chassis systems, making it relevant to qualified migration and expansion projects. 
• Procurement clarity — The exact PID, module type and quantity make it easier to distinguish this set from the older NCS-FAB-OPT 1T optical module set.
• NCS 6000 ecosystem alignment — Using Cisco-specified fabric optics helps maintain the intended optical interface between supported NCS 6000 fabric components.
