Product Review

The CISCO 15216-MD-ID-50 offers a low Polarization Mode Dispersion (PMD) of 0.3 ps and a Polarization-Dependent Loss (PDL) of 0.4 dB, indicating high signal integrity for optical networking. With an Optical Return Loss of 40.0 dB, it ensures minimal signal reflection, enhancing network performance. However, its reliance on LC-UPC II connectors might limit compatibility with some existing network infrastructure.


The CISCO 15216-MD-ID-50 is a specialized device designed to enhance and optimize network performance through advanced optical networking capabilities. This device is tailored for networks that require high levels of data integrity and speed, making it an essential component for telecommunications providers, large enterprises, and data centers that manage large volumes of data transmission. At the core of the CISCO 15216-MD-ID-50's specifications is its exceptional handling of polarization mode dispersion (PMD), which is maintained at a minimal 0.3 ps. This low PMD value is crucial for maintaining the integrity of optical signals over long distances, ensuring that data transmission remains both fast and reliable. The device's ability to keep PMD to such a low level makes it an ideal solution for applications that cannot tolerate signal degradation, such as high-speed broadband networks and critical data links. Another key specification of this device is its polarization-dependent loss (PDL), which stands at 0.4 dB. This measurement indicates the device's efficiency in maintaining signal strength despite the polarization of light in the fiber, which can often lead to variations in signal loss. By keeping the PDL low, the CISCO 15216-MD-ID-50 ensures consistent performance and reduces the likelihood of data errors due to signal attenuation. Optical return loss is another critical specification, with the CISCO 15216-MD-ID-50 boasting a high rating of 40.0 dB. This high level of optical return loss is indicative of the device's effectiveness in minimizing back reflections, which can cause interference and degrade the quality of the signal. By effectively managing these reflections, the device helps to maintain a clear, uninterrupted signal path, which is essential for the transmission of high-speed data. The device is designed to operate efficiently in a wide range of environmental conditions, with an operational humidity range of 5-95% noncondensing. This broad humidity tolerance ensures that the device can perform reliably in various climates and conditions without the risk of condensation affecting its components or performance.
  • Polarization Mode Dispersion (PMD): 0.3 ps
  • Polarization-Dependent Loss (PDL): 0.4 dB
