Product Review

The Cisco DWDM-XENPAK-59.79= transceiver offers a 10GBASE speed over a 40 km reach on single-mode fiber, supporting dense wavelength-division multiplexing (DWDM) for efficient bandwidth utilization. Its compatibility with a 100 GHz ITU channel spacing and inclusion of digital optical monitoring (DOM) support enable precise wavelength tuning and performance monitoring. However, the XENPAK form factor may limit its use in newer, more compact network environments that favor smaller transceiver types.


The Cisco DWDM-XENPAK-59.79= is a plug-in form factor transceiver designed for high-speed data communication over single mode fiber (SMF). It operates on a dense wavelength division multiplexing (DWDM) channel 37 with a precise wavelength of 1559.79 nm. This device is engineered to facilitate 10 Gbps data link protocols, making it well-suited for high-bandwidth applications. One of the key features of this transceiver is its support for the 10GBASE speed, enabling seamless connectivity and fast data transmission rates essential for network backbones and high-speed data centers. The ITU channel spacing of 100 GHz allows for efficient spectrum use, accommodating multiple signals over the same fiber strand without interference, which is critical in densely populated network environments. The Cisco DWDW-XENPAK-59.79= comes with an SC connector, providing a secure and reliable physical connection to the network. This connector type is widely used in fiber optic networks due to its locking feature, which ensures a stable connection that is less susceptible to accidental disconnections. The device supports a maximum reach of 40 km, offering flexibility in connecting distant network nodes without the need for signal amplification or repeaters. Digital Optical Monitoring (DOM) support is another integral feature of this transceiver, allowing for real-time monitoring of the system's operational parameters, such as temperature, optical power levels, and laser bias current. This capability is crucial for proactive network maintenance, ensuring the longevity of the hardware and minimizing downtime. Operating within a temperature range from 0 °C to 70 °C, the Cisco DWDM-XENPAK-59.79= is designed to withstand various environmental conditions, ensuring reliable performance in both indoor and outdoor installations. Its wired connectivity technology guarantees a stable and secure data transmission path, free from the interference issues commonly associated with wireless connections.
