Ciena has announced the addition of hybrid optical electrical ROADM capability to its 4200 optical platform
"creating the only solution that uses a hybrid electrical and optical ROADM design to combine whole and sub-wavelength switching in one platform. Through efficient electrical grooming of services onto each wavelength, the CN 4200 ROADM uses up to 78 percent fewer wavelengths and, for the first time, brings the benefits of reconfigurable optical technology to any service rate down to 155 Mbps.
