We propose and demonstrate experiment transport of 8x32Gbit/s DWDM system structure in L band wavelength range which use the combination of Large Effective Area Fiber (LEAF) and Reverse Dispersion Fiber (RDF) as dispersion compensation device [1,2]. L band wavelength range 1570.42 nm~1576.02 nm channel spacing 100GHz.Combine Erbium Doped Fiber Amplifier (EDFA) which use the combination of LEAF and RDF as dispersion compensation device is proposed and demonstrated [3]. The system structure transmission length of 680 km consisted of 63.75 km LEAF and 4.25 km RDF for ten fiber spans. Good performances of Q factor better than 6 dB, corresponding to a Bit Error Rate (BER) of less than 10 -9 , have been measured for all eight channels. This proposed system is suitable for DWDM systems in long distance transmission.

“…In order to satisfy the Forward Error Correction (FEC) requirement, the minimum value of Q-factor should be 7.94 (BER ≈ 10 -15 ) [5]. However, the Q-factor obtained in (1) is a unit-less quantity and can be expressed in decibels (dB), where Q dB = 20log 10 Q.…”

“…By using ROADMs carriers would be able to achieve reconfigurability on wavelengths in every corner of their optical network -starting from the metro core to the small office network. [1][2][3][4][5][6]. ROADM subsystems can be built using MicroElectro-Mechanical Systems (MEMS) [6], liquid crystal [7], or Planar Lightwave Circuit (PLC) [8-9] based technologies.…”

OPN04-5: Hybrid Low Loss Architecture for Reconfigurable Optical Add/Drop Multiplexer

et al. 2006

View full text Add to dashboard Cite

Reconfigurable Optical Add/Drop Multiplexers (ROADMs) manufactured with different designs and technologies are soon going to be available in the market. Unfortunately, the latest available ROADM architectures are either suffering from high insertion losses or high manufacturing costs that prevent their rapid deployment in the network. In this paper, we propose a low-loss hybrid architecture for a ROADM subsystem that combines the best features of the latest available ROADM designs. A metro network testbed has been designed and simulated in order to compare the performance of different ROADM modules. The obtained results indicate that our proposed Hybrid-ROADM module performs better than the latest available ROADM subsystems and would reduce the overall network operating costs.
