The ​​15454-OPT-AMP-C=​​ is a C-band Erbium-Doped Fiber Amplifier (EDFA) module for Cisco’s ONS 15454 MSTP, critical for extending reach in dense wavelength-division multiplexing (DWDM) networks. This article analyzes its technical design, integration requirements, and sourcing options, leveraging Cisco’s documentation and insights from ​​itmall.sale​​, the authorized supplier.

Core Functionality and Technical Specifications

The ​​15454-OPT-AMP-C=​​ amplifies optical signals across the ​​C-band spectrum (1525–1565 nm)​​, addressing signal loss in long-haul and metro DWDM systems. Key specifications include:

• ​​Gain range of 16–23 dB​​ adjustable via Cisco Transport Planner software.
• ​​Noise figure <5.5 dB​​ to maintain OSNR (Optical Signal-to-Noise Ratio) for 100G/200G coherent channels.
• ​​Hot-swappable design​​ with dual power supplies for redundancy in mission-critical deployments.

This module supports ​​bidirectional amplification​​, making it ideal for passive optical networks (PON) and submarine cable repeaters.

Compatibility and Deployment Scenarios

A common user question is whether the ​​15454-OPT-AMP-C=​​ integrates with older ONS 15454 chassis. Cisco’s guidelines confirm:

• ​​Compatible with ONS 15454 M6 and M12 shelves​​ running ​​Cisco IOS XR 7.5.1 or later​​.
• ​​Requires paired deployment with OSC-CSM cards​​ for optical supervisory channel (OSC) management.
• ​​Not recommended for Raman amplification setups​​ without additional dispersion compensation.

Typical use cases include:

• ​​Long-haul terrestrial networks​​ spanning >1,000 km.
• ​​Metro DCI hubs​​ with high channel counts (>80 wavelengths).

Procurement Advantages via “15454-OPT-AMP-C=”

While Cisco.com details technical thresholds, ​​itmall.sale​​ enhances procurement with:

• ​​Cisco-certified refurbished units​​ tested for gain flatness and polarization-dependent loss (PDL).
• ​​Custom gain profile configurations​​ to match existing DWDM line systems.
• ​​Extended warranty options​​ covering pump laser failures.

Addressing Critical User Concerns

​​Q: How does this module differ from the OPT-AMP-L= variant?​​
A: The ​​OPT-AMP-C= operates in the C-band​​, whereas the L= variant covers the ​​L-band (1570–1610 nm)​​, ideal for expanding capacity in legacy systems.

​​Q: Can itmall.sale assist with gain tilt adjustments for mixed fiber spans?​​
A: Yes, their engineers provide ​​pre-deployment gain tuning​​ using Cisco’s NFM-T (Network Management System) templates.

Operational Insights

The ​​15454-OPT-AMP-C=​​ is indispensable for operators pushing DWDM limits, but its efficacy depends on precise gain alignment. While ​​itmall.sale​​ offers reliable hardware, always validate span loss budgets with Cisco’s ONS 15454 EDFA Calculator before deployment. Neglecting this step risks OSNR degradation, especially in ultradense 200G+ networks. Prioritizing proactive gain management with this amplifier can significantly reduce post-deployment troubleshooting.
