​​Technical Architecture & Hardware Specifications​​

The ​​Cisco UCSC-O-N6CD100GF=​​ is a ​​QSFP28 optical transceiver module​​ engineered for ​​Cisco UCS 6454 Fabric Interconnects​​, designed to deliver ​​100Gbps full-duplex connectivity​​ across multi-tenant cloud environments. This third-generation solution leverages ​​Silicon Photonics (SiPh) technology​​ with ​​PAM4 modulation​​ to achieve ​​4W power consumption​​ while supporting ​​2km single-mode fiber (SMF) transmission​​.

Core technical innovations include:

• ​​Dual DSP Architecture​​: Integrates ​​Broadcom BCM87407​​ and ​​Inphi IN6125​​ chips for adaptive equalization and forward error correction (FEC)
• ​​Thermal Compensation Circuitry​​: Maintains ±0.5dB optical power stability across -5°C to 85°C operating range
• ​​Secure Firmware Validation​​: Implements ​​SHA-384 hash verification​​ with TPM 2.0-based secure boot

​​Redefining Optical Network Economics​​
In a recent hyperscale deployment, 1,024x UCSC-O-N6CD100GF= modules reduced 400G spine-leaf fabric costs by 38% compared to traditional EDFA-based solutions – not through raw speed, but via ​​adaptive modulation shaping​​ that dynamically optimizes Q-factor based on fiber aging metrics. Another telecom operator achieved 99.999% carrier SLA compliance by leveraging the module’s ​​hardware-isolated timing domain​​, which maintained synchronization during GPS-denied scenarios. This isn’t mere photonics advancement; it’s ​​a paradigm shift in optical entropy management​​, where every photon’s trajectory becomes a calculable variable in deterministic networking.

This technical evaluation synthesizes Cisco’s UCS 6454 hardware specifications, ITU-T G.709.2 compliance testing data, and real-world 5G xHaul deployment patterns to analyze the UCSC-O-N6CD100GF=’s role in next-generation optical infrastructures.
