We report on 107 Gb/s transmission using an integrated ETDM receiver, which comprises 1:2-demultiplexing and clock & data recovery on a single chip. The ETDM receiver was tested successfully in a transmission experiment over 480 km dispersion managed fiber and in a 160 km full ETDM field trial.
Current 100-Gbit/s full-electrical time division multiplex (ETDM) transmission technologies are examined. The focus is on the electrical and electro-optical components, the state-of-the-art and the still existing bottle necks, mainly regarding the formats on-off keying (OOK) and differential quadature-phase shift keying (DQPSK). But also a comparative look on a promising rival solution with non-full...
This paper reviews the current status in ultra-high speed electronics and optoelectronic components and reports on the recent progress in serial ETDM transmission technologies at channel- bitrates of 85...107 Gbit/s. The challenges associated with 100 Gbit/s ETDM transmission and subsystems implementation are addressed.
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.
We report on a complete serial 107 Gbit/s ETDM NRZ transmission system and assess system performance in an error free transmission experiment over 320 km SSMF with 3.5 dB OSNR margin.
