数据中心和网络中100G正在驱动400G解决方案需求增长

  The extensive deployment of 100g connections in data centers and networks is driving the growth of demand for 400g solutions and providing funding for the development of 400g devices. Those suppliers who have successfully developed competitive 100g optical modules and components are expanding 100g capacity, developing lower cost 100g solutions, and introducing 25g, 50g, 200g, 400g and 600g products.

  The extensive deployment of 100g connections in data centers and networks is driving the growth of demand for 400g solutions and providing funding for the development of 400g devices. Those suppliers who have successfully developed competitive 100g optical modules and components are expanding 100g capacity, developing lower cost 100g solutions, and introducing 25g, 50g, 200g, 400g and 600g products.

  The first 100g Ethernet solution came out in 2010. Since then, due to the high cost of optical modules and demand constraints, 100g shipment growth is slow. By 2016, the introduction of qsfp28 module has significantly reduced the cost of 100g port, and the migration of super large data center operators to cloud services has brought huge demand.

  Therefore, 2017 has proved to be the "hockey *" year for 100g Ethernet, and optical module manufacturers are striving to meet the market demand. At present, the focus of optical module and device suppliers is to increase 100g production capacity and reduce costs, so as to "cash out" from this wave of demand. The cost reduction methods include innovative module packaging, silicon photonics, smaller size modules such as sfp-dd, and reducing the number of channels / wavelengths.

  The first 400g optical module used in data center and enterprise is cfp8 packaging mode, and is being commercialized. The next generation will use qsfp-dd or OSFP. 100g with dp-qpsk coherent receiver has been widely used in data center interconnection, man and long distance network. Enhanced DSP can now achieve 200g by 16QAM modulation, while the next generation can support 400g and 600g by 64QAM modulation. These developments are critical to meeting bandwidth requirements between data centers.

  The new report "from 25 / 100g to 400 / 600g: competition analysis of optical modules and devices" released by heavy reading comprehensively analyzes the manufacturers of optical modules and devices developing 25g / 100g / 200g / 400g / 600g ports, introduces more than 450 different products and product combinations from 49 suppliers, and analyzes their main characteristics and advantages.

  Heavy reading said that at present, there are nearly 30 manufacturers providing qsfp28 modules and active optical cables for 100g data centers and enterprise applications. Many manufacturers have also introduced sfp28 modules that support 25g Ethernet to server. Some manufacturers can provide 100g CFP, cfp2, cfp4 and CXP modules. The shipment of qsfp28 is psm4 and cwdm4 ports used in super large scale data center and other applications. The first 200g optical module introduced by the manufacturer adopts qsfp56 package and pam4 coding, or qsfp-dd package and two 100g ports.

  Data center interconnection, Metro and toll systems use DSP integrated into line card module or pluggable cfp-dco module.

  Most leading telecom system manufacturers have their own DSP designs. Several companies use DSP integrated on-line cards and pluggable cfp2-aco modules that contain only analog and optical components. This is an important innovation area for suppliers to develop the next generation of 400 / 600g DSP design, 200g cfp2-dco module and 400g module. OIF is working on the 400zr interface standard of 80-120km, and ciena has authorized three optical module companies (lumentum, neophotonics and octaro) to use their 400g coherent DSP chips.

  Coherent transceiver DSP and gearbox components, pam4 phy and CDR components, optical driver / receiver array and packet optical transmission platform components are the key to build these optical modules and line cards. At present, the latest generation of devices adopts 16nm CMOS technology, and the next generation of DSP is expected to adopt 7Nm technology. Pam4 phy and 50g CDR can achieve dual wavelength 100g and four wavelength 200g solutions. The next generation of components will support single wavelength 100g.

  Heavy reading said that the demand for 100g optical modules in data centers and other application markets is very strong. With the decline of module cost and the gradual increase of production capacity to meet the demand, the market for 100g optical modules in 2018 will be highly competitive. At present, the first solutions of 200g and 400g are available. At present, the industry is trying to reduce the cost of 100g, develop higher density 400g, 800g and 1.6tbit/s solutions. All methods are adopting advanced coding and modulation methods, especially pam4 applied in data center and enterprise, and 16 / 64 QAM applied in data center interconnection, Metro and long distance. These R & D require a lot of investment from suppliers, which may lead to further integration of the industry.

  The optical module providers covered in the report include Acacia, Amphenol, AOI, champion one, Cisco, colorchip and effdon Networks, eopolink, Finisar, fit, FOC, gigalight, Hisense, innolight, inphi, Intel, kaiam, lumentum, Luxtera, mellanox, Menara (now a wholly-owned subsidiary of IPG), MOLEX, NEC, neophotonics, octaro, OE solutions, oplink, optore, prolabs, reflex, smartoptics, source photonics, Sumitomo Electric, te connectivity and Wuhan ray Optek.

  *On hockey stick effect Effect): also known as hockey stick phenomenon or hockey stick effect, it refers to that in a fixed cycle (month, quarter or year), the sales volume is very low in the early stage, and there will be a sudden growth at the end of maturity. In a continuous cycle, this phenomenon will start again and again, and the shape of its demand curve is similar to hockey stick, so it is called hockey stick in supply chain management )Phenomenon.
