Abstract

We demonstrate a regenerative optical grooming switch for buffer-less interconnection of metro/access and metro/core ring networks with switching functionality in time, space and wavelength domain. Key functionalities of the router are the traffic aggregation with time-slot interchanging (TSI) functionality, the WDM-to-ODTM multiplexing and the OTDM-to-WDM demultiplexing of high-speed channel into lower bit-rate tributaries as well as multi-wavelength all-optical 2R regeneration of several higher-speed signals. BER and Q-factor measurements of different switching scenarios show excellent performance with no error floor and Q-factors above 21 dB.

Fig. 1
Fig. 1 Network scenario and switch node. (a) Two metro/access rings are interconnected to a metro/core ring via the grooming switch. Each ring carries a multiple of WDM channels, either at 43 Gbit/s or 130 Gbit/s per wavelength. (b) Grooming switch block diagram. Traffic from the metro/access rings is switched by the space switch either to the other access rings, or via the add path to the metro/core ring. Conversely, an OTDM channel from the metro/core ring can be dropped, and any of the three OTDM tributaries may be mapped to any of the metro/access rings or back to the core ring. The signals in this plot show one possible switching scenario: Three OTDM tributaries at λcore1 are dropped to the OTDM-to-WDM converter. Two of its outputs (carrying time-slots TS1 and TS3) are switched to the WDM-to-OTDM converter, slot-interchanged and looped back to the core ring. Channel λacc1 from metro ring 1 is added and mapped to time-slot TS2. In addition, the dropped time-slot TS2 is mapped to λacc2 on metro ring 2.

A small maximal penalty of 2.2 dB compared to the back-to-back (B-to-B) signal is observed for the 1560.6 nm output signal.

Fig. 4 WDM-to-OTDM traffic grooming utilizing the asynchronous retiming concept. The incoming 43 Gbit/s signals are synchronized to a local oscillator, wavelength converted and the pulse width is shortened using three ADOREs. The output short pulse signals are temporally aligned and combined to form the 130 Gbit/s OTDM signal. Sync. – synchronization; WLC – wavelength conversion; MLL – mode-locked laser.

Fig. 6 Operation principle of the fiber-based 2R regenerator. The two degraded 130 Gbit/s input signals are individually amplified and counter propagate in the HNLF, where self-phase modulation (SPM) induced spectral broadening takes place. In combination with subsequent offset filtering this leads to the regenerated output signals. Eye diagrams indicate excellent regenerative performance in dual-channel operation.
