Product Review

The Cisco 15454-40EX-TXP-C module offers a broad operating wavelength range from 1530 nm to 1565 nm with an output power range of 0 to 3 dBm, catering to diverse networking requirements. However, its maximum Differential Group Delay (DGD) of 7.7 ps may limit performance in high-speed, long-distance applications. Additionally, the module's operating temperature range is suitable for standard data center environments, but its upper limit of 40 °C could be restrictive in hotter climates without adequate cooling.


The Cisco 15454-40EX-TXP-C is a high-performance, external modulation optical transponder designed for versatile and efficient networking hardware solutions. It operates within the Very Short Reach (VSR) interface type, ensuring compatibility with a range of networking environments. This device is engineered to facilitate reliable, high-capacity optical transmission, making it suitable for a variety of applications that require robust data transport capabilities. At the core of its specifications, the transponder supports an operating wavelength range from 1530 nm to 1565 nm, accommodating a broad spectrum of optical networking requirements. It features a minimum output power of 0 dBm and can go up to a maximum of 3 dBm, providing flexibility in signal strength based on the needs of the network. The device also boasts a minimum optical return loss of 24 dB and an extinction ratio of 8.2 dB, ensuring efficient signal transmission with minimal loss. The optical receiver type of the Cisco 15454-40EX-TXP-C is PIN, which is known for its high sensitivity and capability to handle higher data rates, making it ideal for long-distance transmission. It supports a maximum receiver reflectance of 27 dB. The transponder uses LC duplex connectors for both transmission (Tx) and reception (Rx), ensuring high reliability and ease of connection. Key features include: - Output power ranging from 1 to 6.5 dBm, providing versatility in adjusting signal strength. - Card LEDs that indicate Failure (FAIL), Active/Standby (ACT/STBY), and Signal Fail (SF), offering straightforward diagnostics and monitoring. - Occupying two slots, the device is designed for efficient space utilization within the networking hardware. The operational temperature ranges from 0 °C to 40 °C under nominal conditions, and from 5 °C to 55 °C for short-term operations, ensuring reliability across various environmental conditions. It also has a storage temperature range from -40 °C to 70 °C, allowing for flexibility in handling and storage conditions without compromising the device's integrity. Humidity levels are another consideration in the design of the Cisco 15454-40EX-TXP-C. It operates within 5% to 85% relative humidity non-condensing under nominal conditions and can withstand 5% to 95% for short-term periods, ensuring performance stability in varying environmental conditions. The maximum Differential Group Delay (DGD) supported by this device is 7.7 ps, indicating its capability to maintain signal timing integrity over the transmission path, which is critical for maintaining high-quality signal transmission. In summary, the Cisco 15454-40EX-TXP-C combines a range of features designed to offer efficient, reliable optical transmission. Its support for a wide operating wavelength range, combined with flexible output power settings and environmental tolerance, makes it a versatile solution for diverse networking requirements. The device's design considerations, such as card LEDs for diagnostics and dual-slot occupancy, further underline its utility in scalable, high-performance networking environments.
