We demonstrate few-km reaches for PCIe-based optical fiber interconnections according to latency limitations, characterizing 16-Gb/s per lane Generation4 up to 10 km and confirming the Generation3 compliance of 2-km links employing suitable PCIe cards.
We discuss system design issues introduced by different ownership models in undersea OADM cables, including the selection of OADM node architectures and the level of OADM reconfigurability.
We present an O-band dual-polarization silicon photonic intensity-modulator for short reach direct-detection applications. We demonstrate 112 Gb/s DP-OOK transmission over 10 km at a BER of 6.6 ×10−6 using a Stokes vector direct-detection receiver.
A multimode waveguide spectrometer with 4 GHz resolution, 250 GHz usable range, and a 1.6 mm × 2.1 mm footprint is demonstrated. The operating range is greatly extended by including distinct mode-exciting elements on chip.
A MEMS tunable hybrid plasmonic-Si (HP) waveguide is investigated, showing very large changes of both effective refractive index and propagation loss when applying bias voltage. Preliminary experimental results show that: with 15μm MEMS structure in Si waveguide platform, the extinction ratio can be over 20dB between "on" and "off states.
We study the cost effectiveness of network re-optimization for both short-term traffic variations and long-term traffic growth. The presented re-optimization operation is effective in reducing equipment cost while curbing the increase of operational cost.
We fabricated 1.3-pm AXELs to extend the transmission distance with 28-Gbit/s-NRZ signal. SOA-assisted gain is effective in increasing the average output power. We successfully demonstrated 80-km transmission with an APD-ROSA.
Current trend of data growth and revenue pattern make multi-layer network technology and architecture selection critical. This paper highlights how combining universal OTN switching and flexi-rate line interfaces can outperform traditional technologies in minimizing CAPEX.
We demonstrate a high output power EML-array operating at 4 × 56 Gb/s NRZ. On chip RF transmission lines enable flexibility for packaging and driver integration. A common active layer structure allows for cost effective fabrication.
We propose a protection scenario for flexgrid networks whereby premium traffic survives cuts with just-enough bandwidth. We demonstrate a novel two-wavelength Baudrate-switchable optical transmitter reconfiguring in <2.8ms. We compute typical spectral usage boosted by 80%.
A tunable all-optical inter-channel interference mitigation method is proposed for an overlapped channel system that avoids the need for multi-channel detection. We experimentally demonstrate the system performance improvement for 16QAM and QPSK overlapped channels for both 20/25 Gbaud data and under different channel spacing conditions.
We transmit 256Gb/s signal through 404km, passing 8 times a hybrid pumping scheme MC-EDFA controlled depending on monitored temperature. Received Q value variations are within ±0.15dB while power consumption is reduced by up to 38.0%.
We discuss a multi-vendor line-side interoperability field trial using Juniper and Cisco 100G coherent DWDM routers interfaces. The field trial demonstrates 100G DP-QPSK transmission over a 1030-km link from Boca Raton to Jacksonville uses the HG-FEC line-side interoperability mode for 100G coherent DWDM transceivers.
A full-polarization optical spectrum analyzer is proposed based on a frequency-swept microwave-photonic source and balanced photodetection. A resolution of 0.75 MHz (6 fm) and a dynamic range of >57 dB were experimentally achieved.
We demonstrate a novel method for monitoring internal paths of optical nodes exploiting light labeling technique. The optical paths of a 2×2 wavelength cross connect could be monitored in 2ms without affecting transmission performance.
Significant improvements in the performance of electronic dispersion post-compensation enabled by beating interference compensation were experimentally demonstrated in a 112 Gb/s/λ WDM Nyquist-subcarrier modulation direct-detection system in transmission over distances up to 240 km.
Hybrid fiber-wireless systems offer the promise of efficient high capacity fiber class data delivery to mobile and fixed wireless devices. Achieving this promise will require systems employing highly linear techniques.
A new method for measuring Optical Signal-to-Noise-Ratio (OSNR) in systems using polarization multiplexed transmission was investigated. The OSNR can be calculated from the correlation between spectral components in the optical spectrum of a transmission signal.
An FPGA-based centralized controller architecture for silicon photonics switches is experimentally demonstrated achieving scheduling decision in one clock cycle. The FPGA simultaneously operates as the controller, and the traffic payload generator with error detection.
