100 Gigabit for the metro

ADVA Optical Networking has launched a 100 Gigabit transmission card designed for metro wavelength-division multiplexing (WDM) applications.

The firm claims this is an industry first: a direct-detection-based 100 Gigabit-per-second (Gbps) design using four, 28Gbps channels rather than current 10x10Gbps schemes.
