“…Several approaches have been studied for labeling optical packets, including serial-bit labeling [2] and sub-carrier multiplexing [3,4]. Simultaneously exploiting two dimensions of the light field, such as the intensity and the phase or frequency, has been suggested to modulate both payload and label on the same optical carrier [5]. Such an ''orthogonal modulation'' labeling method is currently gaining more interest [6].…”

“…The modulation formats explored in optical packet switching could be amplitude shift keying (ASK), differential phase shift keying (DPSK), frequency shift keying (FSK) or polarization shift keying (PolSK). Recent experiments [5,6] show that at 40 Gbit/s, the DPSK and PolSK modulation formats are promising techniques to overcome nonlinear impairments and to extend the transmission distance [7].…”

Orthogonal ASK/DPSK labeling, which encodes label information on optical carriers in a modulation format, is regarded as a competing scheme to subcarrier multiplexed optical labeling. However, the inherent cross-talk limits the extinction ratio (ER) of the payload and label sensitivity. In this paper, two optical coding methods-Manchester coding and 8B10B coding-which can remarkably improve the system quality to obtain acceptable ER are discussed. A novel optical packet encoding methodmark-insertion coding-is demonstrated to significantly reduce cross-talk between the amplitude shift keying (ASK) payload and the differential phase shift keying (DPSK) label through spectrum shaping. The performance of mark-insertion coding depends on the number of inserted 'marks'. Finally, the transmission over a 40 km single mode fiber (SMF) is compared with optical label swapping for a 40 Gbit/s ASK payload and 2.5 Gbit/s DPSK label under these coding schemes. The experimental result is consistent with the theoretical analysis.

“…Optical labelling using orthogonal modulation formats has been an emerging topic already in the early 1990's, work in Leonid Kazovsky's group at Standford University on the STARNET network [1][2] [3], and was revived in the early to mid-2000's, European project STOLAS (Switching Technologies for Optically Labelled Signals), followed by a number of groups worldwide. However, previous studies were based on low bit-rate networks, and 100Gb/s backbone network is applied to commercial network now [4], researches on this high bit-rate transmission network is necessary.…”

Abstract. Two orthogonal modulation optical label switching (OLS) schemes, which are based on payload of polarization multiplexing-carrier suppressed return to zero-differential quadrature phase shift keying (POLMUX-CSRZ-DQPSK) with label identifications of duobinary (DB) label and pulse position modulation(PPM) label, are proposed in high speed OLS network. The receiver performance of two optical labels and the optimized extinction ratio (ER) are compared with amplitude shift keying (ASK) label by simulation in long transmission distance. The results show DB label has more advantages in fast optical label switching system, and PPM label can improve receiver sensitivity of payload significantly. Two labels have excellent performance in high bit-rate transmission system.

“…In addition to the optical wavelength that can serve as an optical label in multiprotocol switching schemes, a second level of optical label is still necessary for provisioning, maintaining, and restoring switched light-paths. This second level optical label can be realized by subcarrier multiplexing (SCM) [2], [3] or by using orthogonal modulation format [4]- [8] combining amplitude shift keying (ASK) and differential phase-shift keying (DPSK) on a single carrier.…”

Abstract-We report an experimental investigation of transmission and transparent wavelength conversion properties of a two-level optically labeled signal using amplitude-shift-keying/differential-phase-shift-keying orthogonal modulation. Error-free transmission of a 10-Gb/s payload and 2.5-Gb/s label over 80-km nonzero dispersion-shifted fiber is achieved with less than 1-dB power penalty. Transparent wavelength label swapping based on four-wave mixing in a highly nonlinear fiber is also demonstrated, clearly validating this orthogonal modulation scheme as a potential solution for optical labeling.Index Terms-Four-wave mixing (FWM), optical labeling, optical packet switching, wavelength conversion.
