10-Gb/s optical transmission up to 253 km via standard single-mode fiber using the method of dispersion-supported transmission

Using the new method of dispersion-supported transmission, 10 Gb/s signals at 1.53 /spl mu/m wavelength are transmitted on standard single-mode fiber with zero dispersion at 1.3 /spl mu/m via the record length of 253 km without in-line regeneration. Detailed experiments with a directly modulated laser demonstrate the system performance for different fiber lengths ranging from 0 up to 253 km. >

Advanced 160 Gbit/s OTDM system based on wavelength transparent 4 /spl times/ 40 Gbit/s ETDM transmitters and receivers

We have demonstrated an advanced 160 Gbit/s OTDM transmission system with a wavelength transparent transmitter concept suitable for DWDM operation. Latest 40 Gbit/s ETDM technology is used for the first time both in the 160 Gbit/s transmitter and receiver along with PLL clock recovery. 160 Gbit/s OTDM transmission has been demonstrated over 2 /spl times/ 100 km of TeraLight/spl trade/ fibre without an error floor. The experiments clearly show that long TeraLight/spl trade/ fibre spans can be bridged without the need for Raman-amplification.

100 Gbit/s ETDM transmission system based on electronic multiplexing transmitter and demultiplexing receiver

We demonstrate a 100 Gbit/s ETDM transmission system with pure electronic signal processing in transmitter and receiver showing error free operation without using OTDM subsystems.

Analog video distribution system with three cascaded 980 nm single-pumped EDFA's and 73 dB power budget

A FTTH (fiber to the home)-system for 35 AM-VSB (amplitude modulation vestigial sideband) PAL TV-signals is presented with three cascaded EDFAs (erbium-doped fiber amplifiers) single-pumped with commercially available 980 nm semiconductor laser diodes, with only one optical isolator per amplifier and without any optical filter. This EDFA design leads to an optical distribution system that is cost competitive as compared to coax solutions. The high-optical output power (+13 dBm) in conjunction with the low noise performance (max NF=4.5 dB) allows a 73-dB power budget for a weighted video signal to noise ratio of 45 dB. A high split count of 4*32*64*64=524288 subscribers is realized.<<ETX>>

Challenges for 100 Gbit/s ETDM Transmission and Implementation

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.

Serial 107Gbit/s ETDM NRZ Transmission over 320km SSMF

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.

Tolerance Analysis of 107 Gbit/s ETDM ASK-NRZ VSB

We report on the tolerances of a 107 Gbit/s ETDM ASK-NRZ VSB DWDM transmission system with respect to laser detuning, receiver filter detuning, DGD, residual chromatic dispersion and nonlinear transmission impairments.
