OFDM in Optical Long-Haul Transmission
In this paper we review two OFDM based architectures, which have recently been proposed for optical long-haul transmission. The BER performance is investigated in presence of chromatic dispersion and differential group delay. In a further step both architectures are extended to polarization diversity receivers. Improvement is achieved by diversity combining at the expense of increased complexity.
متن کاملCoherent Optical OFDM System or Long-Haul Transmission
In this paper, the coherent optical – orthogonal frequency division modulation (CO-OFDM) technique for transmission of optical signal at 10Gbps data rate has been investigated. The CO-OFDM technique has been evaluated using quadrature phase shift keying (QPSK) modulation technique. The use of Dispersion compensation fiber (DCF) in various compensation schemes, i.e., post, pre and symmetrical co...

متن کاملOptical Monitoring for Non-Linearity Identification in Long-haul O-OFDM Transmission
Optical monitoring at end-terminals is considered a cost efficient technique. Utilizing coherent detection allows separating linear and non-linear effects. Channel identification in CO-OFDM receivers is proposed as candidate to achieve this objective. © 2007 Optical Society of America OCIS code(s): (060.2330) Fiber optic communication; (060.4080) Modulation
