Product Review

The CISCO 15454-DM-L1-30.3 supports dense wavelength division multiplexing on the Cisco ONS 15454 platform, offering 4 channels with a multirate capability up to 2.5 Gbps and tunable across the C and L bands, enhancing network flexibility and efficiency. However, its reach, though substantial at up to 122 miles for 16 channels, may limit deployment in larger networks requiring longer, uninterrupted spans without signal regeneration. Compatibility with various Cisco shelf assemblies and the provision for expansion via an SFP slot ensures easy integration into existing infrastructures but highlights the necessity for careful planning regarding future network scaling and compatibility.


The CISCO 15454-DM-L1-30.3 is a versatile component designed for the Cisco ONS 15454 Multi-Service Platform, facilitating dense wavelength division multiplexing (DWDM) applications. This hardware is engineered to support four channels, making it a key player in optimizing network capacity and efficiency. Its multirate capability ensures compatibility with various data rates, enhancing its utility across different network requirements. Operating at a frequency of 195.9 THz and a wavelength of 1530.33 nm, the device is specifically tuned for the C band, offering a speed of 2.5 Gbps. This ensures high-performance data transmission across networks. Its tunable nature allows for flexible deployment in dynamic networking environments, adapting to varying bandwidth needs without the need for physical hardware changes. Key specifications include: -
  • Compatibility with Cisco ONS 15454 Multi-Service Platform.
  • Expansion slot for 1 SFP module, allowing for easy upgrades and scalability.
  • Support for Timing, communications, and control card (TCC) TCC2P, enhancing network timing and synchronization.
The device also integrates with the Alarm Interface Controller (AIC) and offers an Alarm Expansion Panel (AEP) option for ANSI, ensuring robust network monitoring and management. It is compatible with various shelf assemblies, including SA-HD, SA-HD-DDR, or SA-ETSI versions, and fan-tray assemblies such as CC-FTA, FTA3-T (ANSI), or FTA-48V (ETSI), providing flexibility in installation and maintenance. In terms of network capacity, the hardware supports up to 20 nodes per network, with the ability to handle 40 + 1 (OSC) wavelengths in the C band, scalable to 80, and 32 + 1 (OSC) wavelengths in the L band, scalable to 64. The wavelength spacing is set at 100 GHz, scalable to 50 GHz, allowing for dense channel allocation and efficient spectrum usage. The optical reach of the device is impressive, supporting single span, point-to-point transmission over amplified 40 channels for up to 106 miles (170 km) and 16 channels for up to 122 miles (195 km). With the capability to manage up to 20 spans, it can cover a ring circumference of up to 1240 miles (2000 km), making it suitable for extensive network deployments. Designed for single-mode fiber (G.652, G.655, G.653), the CISCO 15454-DM-L1-30.3 ensures high-quality, long-distance signal transmission, supporting the backbone of modern communications networks. Its application in DWDM significantly increases bandwidth, allowing for the simultaneous transmission of multiple data channels over the same optical fiber, thereby maximizing network capacity and efficiency. In summary, the CISCO 15454-DM-L1-30.3 is a critical component for network operators seeking to enhance their DWDM capabilities. Its support for multiple channels, combined with its tunable and multirate features, offers a scalable solution that can adapt to evolving network demands, providing a reliable foundation for high-speed data transmission and efficient network management.
