Product Review

The Cisco 15454-40-WXC-C= module offers a 40-channel capacity with MEMS filter technology, supporting dense wavelength division multiplexing (DWDM) applications with a minimal insertion loss of 5 dB and an efficient power draw of 25 W. However, its maximum input power limitation of 25 dBm and polarization dependent loss of up to 0.6 dB could restrict performance in high-power or polarization-sensitive environments. Additionally, the module's operational temperature range from -5 °C to 55 °C and humidity resilience from 5% to 95% make it versatile for various installation conditions, though the maximum storage temperature cap at 70 °C may necessitate careful monitoring of storage conditions.
