Product Review

The Cisco 15454-40-WSS-C= module offers a dynamic range of 20 dB and supports up to 40 channels with an insertion loss of 7.5 dB, catering to efficient bandwidth utilization and signal integrity in dense wavelength division multiplexing (DWDM) systems. However, its maximum polarization dependent loss of 3.5 dB and power draw of 63 W might be limiting factors in scenarios demanding higher energy efficiency and lower signal distortion. The device's broad operating temperature range (-5 °C to 55 °C) and humidity tolerance ensure reliability across various environmental conditions, although its relatively high maximum input power requirement (25 dBm) could necessitate additional power management strategies in complex network setups.


The Cisco 15454-40-WSS-C= is a wavelength selective switch designed for the C-band, supporting 40 channels. This device is engineered to manage and route optical signals in dense wavelength division multiplexing (DWDM) systems, making it an essential component for modern high-capacity networks. Its core functionality is built around an array wave guide filter type, ensuring precise wavelength selection and efficient signal routing. One of the key specifications of this device is its insertion loss, which is rated at 7.5 dB. This measure is critical as it indicates the amount of signal strength lost due to the switch, impacting the overall performance of the optical network. The device also boasts a variable optical attenuator (VOA) with a dynamic range of 20 dB, providing flexibility in managing signal strength across different channels. The maximum input power the device can handle is 25 dBm, accommodating high-power signal transmission without degradation. For network designers, understanding the device’s handling of optical power is crucial for ensuring system reliability and performance. The Cisco 15454-40-WSS-C= also features a minimum transmit filter bandwidth of +/-135 pm, which is critical for maintaining signal integrity and minimizing distortion. Crosstalk is a significant concern in dense networks, and this device addresses it with an adjacent crosstalk specification of 30 dB and non-adjacent crosstalk of 42 dB. These figures indicate the device's effectiveness in isolating channels from each other, preventing interference and preserving signal quality. Additionally, the maximum polarization dependent loss is kept at a minimal 3.5 dB, further ensuring signal fidelity across various polarization states. Accuracy in optical power settings is vital for network optimization, and the Cisco 15454-40-WSS-C= achieves this with an optical power setting accuracy of -0.7/0.7 dB. This precision allows for fine-tuning of signal levels, enhancing the overall network efficiency. Furthermore, the device ensures a minimum return loss of 40 dB, minimizing signal reflection that could lead to data corruption. From a connectivity standpoint, the device utilizes MPO ports for channel input/output and LC composite ports, providing flexibility and compatibility with a wide range of optical network infrastructures. It also has a power draw of 63 W and requires two slots for installation, making it a relatively efficient component in terms of energy consumption and space utilization. -
