Matched suite of 64 Gbd coherent optical components available from NeoPhotonics
NeoPhotonics has made available its suite of 64 GBd optical components for coherent systems operating at 600G and 1.2T, now shipping to customers.
Consisting of three critical optical components - a 64 GBd coherent driver modulator, 64 GBd coherent intradyne receiver and an ultra-narrow linewidth tuneable laser – the suite works together to enable customers to implement single channel 600G or dual channel 1.2T data transmission over datacentre interconnect (DCI) distances of 80 km.
The 64 GBd CDM polarization multiplexed, quadrature coherent driver modulator is shipping in limited availability and features a co-packaged indium phosphide (InP) modulator with a linear, high bandwidth, differential driver in a compact package designed to be compliant with the anticipated OIF Implementation Agreement. Co-packaging the InP IQ modulator with the driver enables an 85% reduction in line card board space compared to equivalent lithium niobate solutions.
In volume production, the 64 Gbd Micro-ICR class 40 high bandwidth micro-intradyne coherent receiver (ICR) is designed for 64 GBd symbol rates, doubling the RF bandwidth of standard 100G ICRs. It supports higher order modulation such as 64 QAM and is designed to be compliant with the OIF implementation agreement OIF-DPC-MRX-02.0.
The company’s Low Profile Micro-TL ultra-narrow linewidth external cavity tuneable laser is now configured in a smaller, lower profile package, which is designed to meet the stringent requirements for packaging density in pluggable modules. The company says that the external cavity laser design has a significantly narrower linewidth than competing designs, which is advantageous for higher order modulation formats.
The three components also support 400G over metro distances of 400-600km using 64 GBd and 16 QAM, or 200G over long-haul distances of greater than 1000km using 64 GBd and QPSK, and NeoPhotonics will exhibit the suite at the OFC Conference in San Diego from 13 to 15 March.
