…groups (two separate 4 x GE ports, Optical Metro 5080 only). In addition, inband communications over GE wavelengths is supported to eliminate the requirement for Optical Supervisory Channel (OSC) wavelengths. This new feature can be enabled on single GE wavelengths and is 100 percent out of band so that…

…looking to maximize their return on capital investment. As end-user demand for more bandwidth increases over time, for example, growing from 100 Mb/s to GE to 10GE, the 565 can address this growth without the need for costly upgrades or retrofits. Further benefits in cost savings can be achieved by…
