Cisco 15216-DCU-950 Dispersion Compensation Unit - Transceiver - plug-in module - for ONS 15216 WMEE2ZJCAA 74-3165-01

As metropolitan (metro) transport networks grow from 2.5-generation (2.5G) services to 10G and eventually 40G, the underlying optical systems need to compensate for the lower chromatic dispersion tolerances on the 10G and 40G interfaces. In optical networks, the dispersion compensation unit (DCU) compensates for accumulated chromatic dispersion effect in fiber.
