FLEXGRID HIGH RESOLUTION OPTICAL CHANNEL MONITOR (OCM)
Through proprietary and patented coherent detection and sub-GHz wavelength accuracy, Coherent’s OCM features highly
accurate power monitoring of ne spectral slices independent of adjacent channel power and without the need for de-con-
volution, making it ideal for next generation networks comprised of individual carriers densely packed into multi-carrier
super-channels. Eectively future proof, it not only complements but enhances new transceiver technologies which allow
transmission rates and modulation formats to be congured for optimum spectral eciency over any transmission link in an
adaptive manner.
Coupled with rapid scanning and powerful advanced processing of spectral characteristics, such as valid channel detection,
center wavelength and OSNR monitoring, it enables precise network tuning during dynamic network actions and reliable
long-term operation.
The unique challenges of extending SDN to the optical transport layer are addressed by the network instrumentlevel teleme-
try enabled by Coherent’s High Resolution OCM.
The High Resolution OCM represents the latest addition to Coherent’s industry leading ROADM and wavelength manage-
ment portfolio, oering unparalleled value to system and network providers through complementary innovations.
