Implementation Agreement For Cfp2-Analogue Coherent Optics Module

Some plug-in modules fit the printed card rather than the front plate. According to Ian Betty, oIF board member and publisher of the gfp2-ACO implementation agreement, one of the historical problems associated with the design of innovative optical components in systems is their long development period. The long development period has made it risky for system manufacturers to adopt such components as part of their optical transport designs. THE PCP2-ACO now eliminates much of this risk; System providers can choose from a number of CFP2-ACO vendors based on module performance and price. With this new approach as well, the CFP2-ACO is a demanding component to design and build. The CFP2 form factor has nominal dimensions of 41.5 mm in width and 91.5 mm in length and 12.4 mm in height. The consistent optical components of the first generation were simply too large to fit the GFP2 packaging. For example, the first coherent receiver defined by the OIF, “Implementation Agreement for Integrated Dual Polarization Intradyne Coherent Receivers” OIF-DPC-RX-01.0 (known as Type 1), in 2010, certain dimensions, including 75 mmx41mm bridles and fiber boots. The recipient himself would absorb almost the entire envelope of the CFP2, an obvious non-departure. Even the Type 2 RIC, defined by the OIF in 2013, was too large and had dimensions such as 45mmx22mm straps and boots. The OIF responded this year with a new MSA agreement for a micro-RIC specifically designed for a CFP2 ACO, “Implementation Agreement for Integrated Dual Polarization Micro-Intradyne Coherent Receivers,” OIF-DPC-MRX-01.0, with maximum dimension, including flanks, boots and 43mmx16mm flanks and pins. Several suppliers currently offer micro-ICR. Many different forms of optical modulation and multiplexing have been used in coherent optical modules.

The definitions of the CFP2-ACO implementation agreement are also deliberately abstract. The optical technology used is not specified, nor is the module`s data flow. “The module doesn`t have system-level information – whether it`s 16-QAM or QPSK [modulation] or what dispersion is,” says Betty. The Optical Internetworking Forum published in 2016 the CFP2-ACO or CFP2 – Analog Coherent Optics Module Interoperability Agreement (IA). This AI supports a configuration where the digital signal processor (DSP) is on the motherboard and analog optical components on the module. This AI is useful when the DSP exceeds the module`s power envelope. [1] The ACO interface can be used in consistent optical applications if the connection provides flexible bandwidth to the system, for example. B in combination with FlexE. The first ACO IA is for the CFP2 module. The typical optical modulation used are dual Polarization Quadrature Phase Shift Keying (DP-QPSK) and QAM-16. Ian BettyThe CFP2-ACO allows a much higher line solution than other available form factors.

The Groove G30, for example, can adapt eight of these modules to a rack-unit line map. “That`s the key that ACOS gives,” says Betty. It`s a force, he says, because it makes the module independent of a data rate and has a larger market, because any coherent ASIC can use that analog front. “It allows the optics guys to innovate, which they do well,” says Betty. In other words, there are design trade-offs: data rates supported by GFP2 modules can achieve a higher overall side-side rate than more smaller modules, each of which supports a lower maximum data rate due to a higher implementation penalty. A specification design defining the mechanical aspects of on-board optics – dimensions, connectors and electrical interface – is already verified by the consortium members.
