The Cisco ONS 15216 Cisco's Metropolitan Dense Wavelength-Division Multiplexing (DWDM) solution is the first metro DWDM solution to deliver instant wavelengths to buildings, premises, or points of presence (POPs). The Cisco ONS 15216 supercharges wavelength services by supporting up to 32 ITU-grid wavelengths, and provides unprecedented transport flexibility with optical filtering, optical add/drop multiplexing (OADM), optical performance monitoring, and amplification. The Cisco ONS 15216 allows service providers to deliver more services per wavelength and more wavelengths per fiber to achieve radical economic benefits.The Cisco ONS 15216 optical filter solution enables service providers to deploy point-to-point, bus, ring, and meshed networks using the terminal filter multiplexing and demultiplexing and OADM. The Cisco ONS 15216 platform provides an open and flexible solution to combine wavelengths launched by the Cisco ONS 15454, ONS 15252, ONS 15201, and ONS 15530. The Cisco ONS 15216 supercharges wavelength services and extends Cisco's optical leadership to metro regional DWDM.This 15216 Base Red Filter supports optical wave length 1546.12 nm / 1546.92 nm / 1547.72 nm / 1548.51 nm / 1550.12 nm / 1550.92 nm / 1551.72 nm / 1552.52 nm / 1554.13 nm /1554.94 nm / 1555.75 nm / 1556.55 nm / 1558.17 nm / 1558.98 nm / 1559.79 nm / 1560.61 nm.
