Cisco UCSX-CPU-I6448HC= Processor: Architectu
Technical Profile of the UCSX-CPU-I6448HC= ...
The DWDM-SFP10G-54.94= is a Cisco-certified dense wavelength division multiplexing (DWDM) SFP+ transceiver designed for long-haul and metropolitan area networks (MANs). Operating on the 1546.12 nm (ITU Channel 54) wavelength, it enables 10 Gbps data transmission over single-mode fiber (SMF) with a reach of up to 80 km. Unlike coarse WDM (CWDM) modules, this DWDM variant supports tighter channel spacing (0.8 nm) for higher spectral efficiency.
The transceiver reduces serialization delay to <1 μs through hardware-based Forward Error Correction (FEC), critical for financial trading or 5G fronthaul applications.
Consumes 1.5W maximum—30% less than comparable third-party DWDM modules—enabling deployment in thermally constrained nodes.
Supports SONET/SDH, 10GE LAN/WAN, and Fibre Channel without requiring software reconfiguration.
Use Cisco’s Channel Spectrum Analyzer tool to validate wavelength alignment and ensure ±0.05 nm deviation from the ITU grid.
Yes, but only if the CWDM multiplexer includes a DWDM pass-through port (e.g., Cisco ONS 15454 MSTP).
G.652.D SMF with ≤0.22 dB/km attenuation. Polarization mode dispersion (PMD) must be ≤0.5 ps/√km for 80 km spans.
Pre-Deployment Checks
Thermal Management
Ensure chassis airflow follows Cisco’s front-to-back cooling guidelines to maintain transceiver temperatures at 25°C–50°C.

.For enterprises seeking certified modules, the DWDM-SFP10G-54.94= is available here, with lifetime warranty coverage and Cisco Smart Net compatibility.
Having deployed DWDM solutions across multiple metro networks, I’ve observed that Cisco’s DWDM-SFP10G-54.94= consistently delivers superior optical signal-to-noise ratio (OSNR) margins compared to vendor-agnostic SFPs. While third-party modules may offer lower upfront costs, their lack of integrated FEC and limited DDM granularity often leads to higher operational expenses during scaling phases. For mission-critical transport layers, this transceiver’s plug-and-play interoperability with Cisco’s NCS ecosystem justifies its premium positioning.
