RELIABILITY OF SIMULATIONS AT 43GB/S : COMPARISON WITH EXPERIMENT AT 8 MODULATION FORMATS ON FIBER IMPAIRMENTS

  • Dischler R.
  • Idler W.
  • Klekamp A.
  • Lazaro J.

Various noise statistics on simulation have been compared with experimental data on 43 Gb/s amplitude shift keying (ASK) and differential phase shift keying (DPSK) formats for chromatic dispersion (CD) and polarisation mode dispersion (PMD) tolerances and nonlinear threshold (NLT). Best agreement is found by Gaussian noise statistics plus inter-symbol-interference.

NEW TRANSMISSION FIBERS FOR FUTURE NETWORKS

  • De Montmorillon L.
  • Nouchi P.
  • Sillard P.

Optical communication systems are characterized by ever increasing capacity, complexity and cost constraints. This paper reviews state of the art in silica-based fibers for optical networks, ranging from long-haul to metro applications.

WHAT HAS HYBRID PHASE / INTENSITY ENCODING BROUGHT TO 40GB/S ULTRALONG-HAUL SYSTEMS ?

  • Bigo S.
  • Charlet G.
  • Corbel E.

Among the modulation formats proposed for WDM transport networks, some have proven particularly promising at 40 Gbit/s channel rate, in particular against intra-channel nonlinear impairments. We discuss the pros and cons of these formats.

FILTERING AND LINEAR CROSSTALK PENALTIES OF ASK AND DPSK 43 GB/S DWDM SYSTEMS WITH 50GHZ CHANNEL SPACING

  • Dischler R.
  • Idler W.
  • Klekamp A.
  • Lazaro J.

43 Gb/s DWDM-50 GHz optical-filtering and linear-crosstalk penalties are experimentally compared for four ASK and four DPSK formats. With respect to duty cycle, all DPSK formats are more robust than ASK formats, DPSK-RZ 50% shows best performance.

43 GBIT/S TRANSMISSION OVER 40.5 KM SMF WITHOUT OPTICAL AMPLIFIER USING A DIRECTLY MODULATED LASER DIODE

  • Pohlmann W.
  • Wedding B.

Using a directly modulated laser diode transmission at 1550 nm without optical amplifiers over 40.5 km SMF is achieved with margin. 25.5 km are bridged with only 860 mV modulation voltage.

TOLERANCES OF DPSK FORMATS TO DISPERSION-MANAGEMENT PARAMETERS IN 43 GB/S SYSTEMS OVER TRANSATLANTIC DISTANCE

  • Bigo S.
  • Charlet G.
  • Corbel E.

We compute the optimum values of the three dispersion management parameters in an N*43 Gb/s submarine system based on DPSK or RZDPSK. We quantify how accurately these values should be adjusted, and confirm the results experimentally.

We describe the numerical model of multiwavelength Raman fiber lasers. It uses an original algorithm which makes the model robust and fast. Comparison between simulation and experiment on Raman laser output powers are presented.

  • Penninckx D.
  • Prunaire M

We experimentally demonstrate that if the transmission ability of transparent backbone network needs to be improved, tuning post-compensation for chromatic dispersion management is more efficient than tuning pre-compensation.
