OTDM add - drop networking using 275 km installed fibres
Introduction: 160 Gbit=s optical time domain multiplexing (OTDM) technology is only interesting if full add-drop functionality can be realised on the existing fibre infrastructure [1]. A 160 Gbit=s OTDM add-drop node based on the gain transparent ultrafast nonlinear interferometer (GT-UNI) has been demonstrated under laboratory conditions [2]. In this Letter we present a 160 Gbit=s OTDM network...
متن کاملTime domain add-drop multiplexing for RZ-DPSK OTDM signals.
We show all-optical time domain add-drop multiplexing for a phase modulated OTDM signal for the first time, to our knowledge. The add-drop multiplexer is constructed of a Kerr shutter consisting of a 375 m long highly nonlinear fiber (HNLF), gamma=20 W(-1)km(-1). Successful time domain add-drop multiplexing is shown for 80 Gb/s RZ-DPSK OTDM signals with a 10 Gb/s base rate.
متن کاملSimultaneous high speed OTDM add-drop multiplexing using GT-UNI switch
Introduction: The key functionality required in OTDM network nodes is add-drop multiplexing [1]. In an add-drop node a low bit rate single data channel will be separated (drop function) from an incoming high bit rate data stream. Simultaneously the remaining data channels should be left undisturbed (through function), and in the remaining vacant time slot a new channel can be added (add functio...
متن کاملGb / s OTDM Networking using Deployed Fiber
We report a 160 Gb/s OTDM network comprising switching and demultiplexing through field deployed fiber. The 160 Gb/s signal was obtained by time-interleaving 16 channels of a 10 Gb/s signal. The add-drop node was realized by using a gain-transparent operation of a semiconductor optical amplifier (SOA). A subharmonic clock recovery with a pre-scaled electro-optical phase locked loop employing an...
