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.
