WavePath 4500™ Product Brief
`
`Wavelength Selective Switch (WSS) with
`Integrated Optical Channel Monitor (OCM)
`
`Enabling the Dynamic and Reconfigurable Optical Network
`
`Capella Photonics’ WavePath 4500™ is a
`Wavelength Selective Switch (WSS) with
`an Integrated Optical Channel Monitor
`(OCM) for Reconfigurable Optical
`Add/Drop Multiplexer (ROADM) and
`Optical Cross Connect (OXC) applications.
`It delivers the highest level of functional
`integration in an extremely compact and
`cost effective module.
`
`The product, which operates effectively
`independent of data transmission rates
`and format, integrates discrete functions
`such as multiplexing, demultiplexing,
`hitless wavelength reconfiguration
`(allowing any incoming wavelength(s), to
`be directed to any output port), dynamic
`channel equalization, wavelength and
`power monitoring, channel blocking, and
`channel configuration verification.
`
`Through its patented Closed-Loop Control
`Systems, the WavePath 4500™ maintains
`optimal coupling and ITU alignment over
`all operating conditions. The automatic
`compensation for environmental changes
`ensures reliable operation over the
`lifetime of the product.
`
`The WavePath 4500™ is available as a 10
`port solution, configurable to either add
`or drop functionality (i.e., 1x9 or 9x1),
`and supports up to 45 channels in the C-
`band spaced at 100 GHz.
