107-Gb/s full-ETDM transmission over field installed fiber using vestigial sideband modulation

107-Gb/s full-ETDM transmission is shown over a 160-km field installed fiber link. A high tolerance towards narrowband optical filtering is demonstrated using vestigial sideband modulation to minimize the spectral width.

Integrated 100 Gbit/s ETDM Receiver in a Transmission Experiment over 480 km DMF

We report an integrated ETDM receiver for 100 Gbit/s, which comprises 1:2-demultiplexing and clock & data recovery on a single chip. The ETDM receiver was tested successfully in a 100 Gbit/s transmission experiment over 480 km dispersion managed fiber.

10,200 km 22/spl times/2/spl times/10 Gbit/s RZ-DQPSK dense WDM transmission without inline dispersion compensation through optical phase conjugation

Using optical phase conjugation with a polarization independent periodically-poled lithium-niobate subsystem, we demonstrate dense WDM 2/spl times/10 Gbit/s RZ-DQPSK transmission over 10,200 km of SSMF with a record accumulated dispersion exceeding 80,000 ps/nm.

Integrated 100-Gb/s ETDM Receiver

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

Mixed data rate and format transmission (40-Gbit/s non-return-to-zero, 40-Gbit/s duobinary, and 10-Gbit/s non-return-to-zero) by mid-link spectral inversion

A polarization-diverse subsystem based on periodically poled lithium niobate waveguides is used as an optical phase conjugator for compensation for linear and nonlinear distortion. We show successful transmission formats of 13 x 40 Gbit/s non-return-to-zero mixed with 6 x 10 Gbit/s non-return-to-zero and 40-Gbit/s duobinary over 8 x 100 km of standard single-mode fiber. A single phase conjugator is used to conjugate all data formats, including the alternative duobinary format, simultaneously.

Optimizing the wavelength configuration for FWM-based demultiplexing in a SOA

In this paper efficient FWM demultiplexing in a SOA using a well chosen wavelength configuration is presented. A 160-Gbit/s OTDM signal is demultiplexed error-free to a base rate as high as 40 Gbit/s.

Interchannel nonlinear transmission penalties in polarization-multiplexed 2 x 10 Gbit/s differential phase-shift keying transmission

We discuss the performance of a multichannel 2×10Gbit?s polarization-multiplexed differential phase-shift keying transmission system. Through simulations and transmission experiments we find that, despite the constant power envelope of non-return-to-zero phase-shift keying modulation formats, polarization multiplexing strongly reduces the nonlinear tolerance and transmission performance at a 2×10Gbit?s line rate with multichannel transmission. This results in a 10 dB power penalty when comparing single- and nine-channel transmission. Additionally, multichannel impairments in differential phase-shift keying and on–off keying are compared for 2×10Gbit?s polarization-multiplexed transmission.
