Understanding the 15454-TDC-CC=
The 15454-TDC-CC= is a Transponder Daughter Card designed for Cisco’s ONS 15454 Multiservice Transport Platform (MSTP). It serves as a critical component for converting client-side optical signals (e.g., Ethernet, SONET) to DWDM wavelengths, enabling long-haul transmission over fiber networks. Unlike generic transponders, this card is optimized for Cisco’s 15454 chassis, ensuring seamless integration with TDM and packet-based architectures.
Key Technical Features
- Card Type: Dual-slot, hot-swappable transponder
- Supported Protocols: SONET/SDH, Ethernet (1GbE/10GbE)
- Wavelength Capacity: Up to 8 channels per card (C-band ITU grid)
- Power Consumption: 45W max under full load
- Compatibility: Works with ONS 15454 MSPP shelves (ANSI and ETSI variants)
Compatibility vs. Alternatives
| Feature | 15454-TDC-CC= | Third-Party DWDM Cards | Cisco 15454-TDC-FC= |
|---|---|---|---|
| Native Cisco Support | Yes | Limited | Yes |
| Data Rate Flexibility | 1G/10G mixed | 10G-only | 10G-only |
| Signal Reach | 80 km+ | 40–60 km | 100 km |
| Use Case | Hybrid TDM/IP | Cost-sensitive upgrades | High-speed core |
The 15454-TDC-CC= excels in mixed-traffic environments, offering dual-rate support (1G and 10G) without requiring separate hardware.
Addressing Critical User Questions
Q: Can this card replace older 15454-TSC/TSD models?
A: Yes, but firmware must be updated to Release 11.0 or later for backward compatibility.
Q: What are common troubleshooting steps for signal loss?
A: Verify fiber polarity (MPO connectors) and ensure DWDM channel assignments match the node configuration.
Q: Does itmall.sale provide genuine 15454-TDC-CC= units?
A: Yes, “itmall.sale” supplies Cisco-certified refurbished modules with 90-day warranties, ideal for legacy network upgrades.
Why Prioritize Authentic Components?
Third-party cards often lack Cisco’s TL1/CLI command support, complicating diagnostics. The 15454-TDC-CC= also includes built-in FEC (Forward Error Correction), reducing bit errors in high-noise environments—a feature rarely replicated in generic alternatives.
Final Perspective
While newer platforms like Cisco’s NCS 2000 series dominate modern deployments, the 15454-TDC-CC= remains indispensable for enterprises maintaining hybrid TDM/IP networks. Its dual-rate flexibility and proven reliability justify the investment, especially when sourced from trusted partners like itmall.sale. For teams balancing budget constraints with performance, this card strikes a pragmatic middle ground.
