Simultaneous high speed OTDM add-drop multiplexing using GT-UNI switch

Simultaneous 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...

Time 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.

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...

Error-free all-optical add-drop multiplexing using HNLF in a NOLM at 160 Gbit/s - Electronics Letters

Introduction: An add-drop multiplexer (ADM) is one of the key elements in optical time division multiplexed (OTDM) networks. Various methods of performing OTDM add-drop have been demonstrated. Recently add-drop operation at 16 10 Gbit=s has been demonstrated with the use of a gain transparent ultrafast nonlinear interferometer (GT-UNI) [1] switch and at 4 40 Gbit=s with travelling-wave electroa...
