Multiplexers
Multiplexers
The Cisco ONS 15216 4 Channel Optical Add/Drop Multiplexers (OADMs) are a set of passive OADMs that allow
the Cisco ONS 15454 Multiservice Transport Platform (MSTP) to address the edge of the optical network in a cost-
effective manner without sacrificing operational ease of use. The Cisco ONS 15216 4 Channel OADMs are well
suited to applications with minimal wavelength requirements and tight space and power constraints, such as cell
site and customer premises terminations. Ten models are available, covering a 40-channel 100-GHz channel plan.

Applications
The Cisco ONS 15216 4 Channel OADM supports standard network topologies such as point-to-point and ring.
With the introduction of omnidirectional and colorless reconfigurable optical add-drop multiplexer (ROADM)
functionality on the Cisco ONS 15454 MSTP, the combined products allow additional network topologies, such as
the termination of a spur or rings, originating on a Cisco ONS 15216 4 Channel OADM, into the colorless ports of
the ROADM node (Figure 2). This configuration does not consume a ROADM degree, allowing the node to scale
beyond eight directions of connectivity in a mesh-ROADM application.
