​​Product Overview and Core Functionality​​

The Cisco ONS-CCC-100G-10= is a ​​100G QSFP28 client-side transceiver module​​ designed for the Cisco Optical Networking System (ONS) platform, specifically optimized for ​​10-kilometer reach​​ in metro and data center interconnect (DCI) applications. This hot-swappable module converts 100G Ethernet client signals to OTN (Optical Transport Network) wavelengths, enabling seamless integration between router interfaces and DWDM transport systems. Its plug-and-play design simplifies deployments in hybrid networks where Layer 2/Layer 3 services coexist with legacy SONET/SDH infrastructure.

Key operational benefits include:

• ​​Protocol transparency​​: Supports OTU4, 100GBASE-LR4, and 100GBASE-ER4 standards.
• ​​Low latency​​: <200 ns for high-frequency trading and financial networks.
• ​​Diagnostics​​: Real-time monitoring via DOM (Digital Optical Monitoring) for power, temperature, and BER.

​​Technical Specifications and Signal Performance​​

The ONS-CCC-100G-10= leverages ​​coherent CFP2-ACO (Analog Coherent Optics)​​ technology, enabling ​​dual-polarization quadrature phase-shift keying (DP-QPSK)​​ modulation. This ensures compatibility with Cisco’s NCS 2000 and NCS 1004 platforms while maintaining interoperability with third-party ROADMs.

​​Critical performance metrics​​:

• ​​Transmit power​​: -6 dBm to +2 dBm (adjustable via NCS software).
• ​​Receiver sensitivity​​: ≤-15 dBm for error-free operation (BER <1e-15).
• ​​Power consumption​​: 14W typical, compliant with IEEE 802.3ba energy standards.
• ​​Fiber type​​: Single-mode (OS2) with LC duplex connectors.

The module’s ​​Forward Error Correction (FEC)​​ uses OpenROADM-compatible Reed-Solomon encoding, correcting errors up to 7e-3 pre-FEC BER.

​​Deployment Scenarios and Industry Applications​​

​​1. Metro Core Networks for 5G Transport​​

Mobile operators deploy the ONS-CCC-100G-10= to aggregate fronthaul traffic from distributed radio units (DUs) to centralized processing hubs. Its ​​synchronization via Precision Time Protocol (PTP)​​ ensures ±50 ns accuracy, meeting 3GPP’s stringent timing requirements for 5G NR.

​​2. Cloud Gateway Connectivity​​

Hyperscalers use this module to interconnect regional availability zones, achieving ​​sub-500 μs latency​​ for distributed database replication. A Southeast Asian cloud provider reduced cross-region failover times by 62% by replacing CFP2-DCO modules with ONS-CCC-100G-10= in their Cisco NCS 1010 nodes.

​​Integration with Cisco NCS and ONS Platforms​​

The module is compatible with:

• ​​NCS 2006​​: For compact metro deployments with 6-slot chassis.
• ​​ONS 15454 MSPP​​: For hybrid SONET/OTN migration scenarios.

​​Configuration prerequisites​​:

• ​​Cisco Transport Controller (CTC) 12.2.1​​ or later for wavelength tuning.
• ​​DWDM channel plan alignment​​: Ensure 50 GHz or 75 GHz grid compliance to avoid spectral collisions.
• ​​Dispersion compensation​​: Mandatory for links >80 km; use Cisco’s DCM-17-XXX modules.

​​Addressing Critical Operational Challenges​​

​​Q: How does the module handle chromatic dispersion in long-haul links?​​
The ONS-CCC-100G-10= integrates ​​adaptive dispersion compensation​​ via software-defined tunable filters, automatically compensating up to 2,500 ps/nm without manual intervention.

​​Q: Is it compatible with alien wavelength architectures?​​
Yes. The module’s ​​ITU-T G.698.4​​ compliance allows it to operate in third-party DWDM systems, though optimal performance requires Cisco’s NCS Transport Planner for power balancing.

​​Procurement and Lifecycle Management​​

The ONS-CCC-100G-10= is sold as a ​​10-year lifecycle​​ product with Cisco’s Defective Media Retention (DMR) service. For enterprises requiring immediate deployment, ​​ONS-CCC-100G-10= availability at ITmall.sale​​ offers expedited shipping and bulk discounts.

​​Practical Implementation Insights​​

While the ONS-CCC-100G-10= excels in metro DCI use cases, its reliance on C-band wavelengths limits flexibility in C+L-band expanded networks. Teams should conduct thorough fiber characterization (PMD/CD testing) before deployment to avoid costly retrofits. For enterprises prioritizing vendor-agnostic interoperability, this module’s OpenROADM alignment future-proofs investments—but its full potential is unlocked only within Cisco’s ecosystem, where features like predictive fault isolation via Cross-Connect Manager (CCM) add measurable operational value.
