NeoPhotonics has begun sampling a Class 40 High Bandwidth Micro-Intradyne Coherent Receiver (HB Micro-ICR) capable of supporting 64 Gbaud symbol rates, which is double the bandwidth of standard 32 Gbaud ICRs.
The company said its new HB Micro-ICR supports higher order modulation up to 64 QAM, which when coupled with NeoPhotonics ultra-narrow linewidth, external cavity Micro-ITLA laser, can achieve 600 Gbps over Datacenter Interconnect distances of 80 km.
Similarly, using Dual Polarization QPSK modulation the HB Micro-ICR extends the reach to 2000 km at 200Gbps, double the data rate of standard coherent transmission. By using NeoPhotonics advanced coherent components, system designers can increase the bandwidth by up to a factor of six and dynamically change the reach and modulation format while keeping the number of components unchanged, enabling software defined networks (SDN) and greatly reducing the cost per bit.
