Integrated 100-Gb/s ETDM Receiver

Abstract

Abstract-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.Index Terms-Electrical-signal processing, Ethernet over wavelength division multiplexing (WDM), high-speed integrated SiGe circuits, optical communication, optical signal processing, 100-gigabit Ethernet (100 GbE).

Ultra-high-speed OTDM transmission technology

“…[2]. The present research work on ETDM technology focuses on 100 Gb/s Ethernet rather than on the next bit rate in the STM hierarchy, which would be 160 Gb/s, e.g., Ref.…”

“…One of these challenges is an optimized combination of wavelength-division multiplexing (WDM) and time-division multiplexing (TDM). [2]. Presently, the first 40 Gb/s systems based on ETDM have been installed and in laboratories the first 100 Gb/s ETDMexperiments have been performed, e.g., Ref.…”

Electronic/photonic interfaces for ultrafast data processing.

“…The current state-of-the-art is represented by a 1:2 electronic DEMUX operating at 100 Gb/s, recently demonstrated using InP HBT technology [11] with 3.8-W power consumption. Another impressive result employed SiGe technology [12]. This circuit performed a 1:2 DEMUX as well as clock recovery at 107 Gb/s, with unquoted power dissipation (but exceeding 5.5 W).…”

Frequency-dependent electric dc power consumption model including quantum-conversion efficiencies in ultrafast all-optical semiconductor gates around 160 Gb/s

“…All-optical demultiplexing, 3R regeneration, and wavelength conversion based on cross-phase modulation (XPM) in SOAs have been achieved for operating frequencies exceeding 100 GHz [3][4][5], and 320-to 640-GHz operation of all-optical SOA gates using ultrafast chirp dynamics has recently been demonstrated [6][7][8]. These devices typically consumed 0.4 to 1.0 W electrical power, while the latest electrical demultiplexer consumes 5.5 W in 100-GHz operation [9]. As the capabilities of SOAs for ultrafast gating have become clear, the lower limit of electric power consumption and its origin have become important design issues.…”
