4×10Gbps WDM transmission over low loss HC-PBGF at 2μm wavelengths is demonstrated using a 2mm long QCSE based InP MZM with Vπ of 6V and ER>20dB. An OSNR of 25dB is required to achieve error free transmission.
Optical injection locking is used to increase the modulation bandwidth and suppress chirp in a single-channel, single-polarization discrete multi-tone bit-loading-optimized transmitter. Transmission through a hollow-core photonic bandgap fiber with negligible signal degradation and distortion is demonstrated.
We demonstrate the transmission of 12 spatial and polarization modes multiplexed on 255 optical channels in ultra-dense WDM using OFDM across the full C-band over 74.17 km 6-mode fiber. An aggregate bit rate of 41.6 Tbit/s is achieved.
This paper presents WDM transmission at 2μm over 1.15km of HC-PBGF with wavelength channels selected to span a 36.3nm waveband. A total capacity of 81Gbit/s was achieved using 4×12.5Gbit/s NRZ-OOK external modulation and 4×7.7Gbit/s 4-ASK Fast-OFDM direct modulation signals.
We investigate a new and simple colorless WDM-PON system with mitigation Rayleigh backscattering noise and twice capacity simultaneously, using M-QAM (M = 16, 32 and 64) OFDM downstream and remodulated OOK upstream signals, respectively.
We demonstrate a 60-km CWDM-TDM PON with 40 Gb/s capacity both down and upstream. The system incorporates technologies such as volume manufacturable transmitters, burst-mode transmission, hybrid SOA-Raman amplifiers, and a cyclic CWDM multiplexer.
The deployment of multifiber, wavelength division multiplexing (WDM) networks can offer significant economic benefits over single fiber networks, because of their ability to relax the restrictions due to the wavelength continuity constraint and the potential to handle future growth. In this paper we introduce a new integer linear program (ILP) formulation for dynamic wavelength allocation in survivable,...
