Product Review

The CISCO 15216-AD1-2-57.3 offers a specific wavelength of 1557.36 nm and operates within a 200 GHz ITU frequency, making it suitable for applications requiring precise wavelength operations. However, its insertion losses for pass-through, drop, and addition at 1.8 dB, 2.1 dB, and 3.2 dB, respectively, could be a limitation for systems demanding lower signal attenuation. Its compact 1 RU form factor facilitates integration into standard 19-inch racks, but the relatively high insertion loss values might necessitate additional amplification in some network configurations.


The CISCO 15216-AD1-2-57.3 is designed for single-channel optical add-drop multiplexer (OADM) applications, operating at a wavelength of 1557.36 nm and an ITU frequency of 200 GHz. This device is engineered to facilitate the insertion and extraction of a single channel into or from a fiber optic link without disrupting the remaining optical channels. It features a form factor of 1 RU, making it suitable for compact installation within a standard 19-inch rack, and has dimensions that include a height of 1.75 inches, a width of 17 inches, and a depth of 12 inches. Key specifications of the CISCO 15216-AD1-2-57.3 include: - Insertion loss performance, with a maximum pass-through loss of 1.8 dB, a maximum drop loss of 2.1 dB, and a maximum addition loss of 3.2 dB. - It employs SC bulkhead adapters for its connectors, ensuring compatibility with a wide range of optical networking equipment. - The device boasts a minimum directivity of 55 dB and a minimum optical return loss of 40 dB, ensuring signal integrity and reducing the likelihood of feedback issues. Additional characteristics of importance are its polarization mode dispersion, which is capped at a maximum of 0.1 ps, and a wavelength tolerance of +/-25 nm. This precision ensures minimal signal degradation over long distances. The device also maintains a passband flatness of 1 dB (maximum), which is critical for maintaining signal quality across the specified bandwidth. Optical power handling capacity is another crucial aspect, with the device capable of handling up to 250 mW of optical power input. This capacity, combined with adjacent and non-adjacent isolation of dropped wavelengths of 30 dB and 40 dB minimum, respectively, underscores the device's efficiency in managing optical signals. Environmental tolerances are also catered for, with the device operating effectively in a temperature range from 0 °C to 70 °C and offering storage temperature tolerances from -40 °C to -85 °C. These specifications ensure reliable performance across a wide range of environmental conditions.
  • Directivity: 55 dB (Minimum)
  • Optical Return Loss: 40 dB (Minimum)
  • Polarization Mode Dispersion: 0.1 ps (Maximum)
In summary, the CISCO 15216-AD1-2-57.3 is tailored for applications requiring precise channel addition or removal in optical networks. Its low insertion loss, high directivity and return loss, and stringent polarization mode dispersion specifications make it a suitable choice for maintaining high-quality signal transmission in single-channel OADM applications. The device's compact form factor, combined with its robust environmental and optical performance specifications, ensures it meets the needs of demanding optical networking environments.
