Product Review

The CISCO A900-IMA2F module, with its dual 40GE ports, offers flexibility in high-speed networking environments, effectively meeting the demands for increased bandwidth. Compatibility with a variety of QSFP optics (QSFP-40G-LR4, QSFP-40G-SR4, and QSFP-40G-ER4) and support for both single-mode and multi-mode fibers enhance its utility across diverse network infrastructures. However, the limitation to just two ports might restrict scalability in larger, more demanding network setups.


The CISCO A900-IMA2F is a high-capacity interface module designed for integration with ASR900 Series Routers, enhancing the routers' capabilities in handling high-speed data transfer and connectivity. This module comes equipped with two ports, each capable of supporting 40 Gigabit Ethernet connections, ensuring efficient and fast data transmission for network operations. It is specifically engineered to cater to the demands of networks requiring high bandwidth and reliable connectivity. Central to its design is the support for various QSFP optics, making it a versatile solution for different networking environments. The A900-IMA2F is compatible with QSFP-40G-LR4, QSFP-40G-SR4, and QSFP-40G-ER4 transceiver modules. This range of support ensures that the module can be deployed in a variety of settings, from short-reach data center interconnects to long-distance campus connections. The module's flexibility is further enhanced by its compatibility with both single-mode and multimode fiber cables. Single-mode fiber options include the QSFP-40G-LR4 and QSFP-40G-ER4 for long-distance applications, while laser-optimized OM3 and OM4 multimode fibers are suited for the QSFP-40G-SR4 in shorter reach scenarios. The connectors play a crucial role in the module's functionality, with LC connectors used for the QSFP-40G-LR4 and QSFP-40G-ER4 modules, ensuring secure and reliable long-distance connections. In contrast, the QSFP-40G-SR4 utilizes MPO/MTP multi-fiber connectors, ideal for high-density, short-reach applications. This design choice underscores the module's adaptability to various network architectures and distances, with coverage ranging from 100 and 150 meters for QSFP-40G-SR4, up to 10 kilometers for QSFP-40G-LR4, and extending to 40 kilometers for QSFP-40G-ER4. Powered by Cisco IOS software, the A900-IMA2F benefits from a suite of features designed to optimize performance, security, and reliability. The software's compatibility is segmented based on the optics used, with releases 3.16.1S supporting QSFP-40G-LR4 and QSFP-40G-SR4, and release 3.18S designated for QSFP-40G-ER4 modules. This ensures that the module's software is finely tuned to the specific requirements and capabilities of the connected optics, enhancing overall system efficiency and reliability. Key specifications include:
  • Number of Ports: 2
  • Port Capacity: 40GE
  • Supported Optics: QSFP-40G-LR4, QSFP-40G-SR4, QSFP-40G-ER4
In conclusion, the CISCO A900-IMA2F interface module stands out as a flexible and efficient solution for expanding the capabilities of ASR900 Series Routers. Its support for multiple QSFP optics and compatibility with both single-mode and multimode fiber cables make it a versatile choice for various networking requirements.
