Cisco 15216-DCU-550 DCF of - 550 ps/nm 15216DCU550

Description:

The Cisco 15216-DCU-550 is a Dispersion Compensation Unit (DCU) designed for use in Dense Wavelength Division Multiplexing (DWDM) optical networks. Optimized for 550 km fiber spans, this module compensates for chromatic dispersion that accumulates over long distances in standard single-mode fiber. It enables the delivery of high-speed services without signal degradation, making it ideal for long-haul and metro DWDM applications requiring optical performance enhancement.
