Ethernet in backbone networks has the potential to provide high-performance and cost-efficient networking solutions. Driven by the rapid growth of Ethernet traffic, it is likely that, in the transport network, the next step in terms of the data rate will be 100 Gb/s. In this paper, we report on an integrated electrical-time-division-multiplexing (ETDM) receiver for 100/107 Gb/s, which comprises 1 : 2 demultiplexing and clock-and-data recovery on a single chip. The ETDM receiver was tested successfully in 100- and 107-Gb/s transmission experiments over 480-km dispersion-managed fiber.
