We investigate three EDFA only amplification architectures for 100G unrepeatered transmission. With > 4 dBQ margin, pre-amplifier only, booster only and both booster and pre-amplifier amplifications can achieve 130, 150 and 220 km reach respectively.
We experimentally demonstrate 77-channel 127-Gb/s PM-QPSK colorless system achieves, with <1 dB SNR penalty, −17 to −6 dBm/channel dynamic-range with relaxed 12 dBm LO power. Impacts from TIA saturation and polarization effects are also shown.
IQ skew measurement of quadrature amplitude transmitter using reconfigurable interference is demonstrated with >20-dB dynamic range. The scheme is compatible with different modulation formats and patterns. Fast tracking scheme for large skew is discussed.
The development of 100 Gb/s transponder technology is progressing rapidly to meet the needs of next-generation optical/IP carrier networks. Video-driven IP traffic growth continues together with the need for ever higher-speed ports on IP routers, Ethernet switches, and OTN cross-connects, thus driving the requirements for cost-effective client and line side 100 Gb/s transponders. For a short time...
