Optical letter communication to OFC before thought this year OFC will be 400G of the world, but to the scene but only in TE and other few booths to see the display of CDFP 400G module, but also basically static display.

Some communications companies exhibit devices for 400Gbps systems, including 64Gbaud EML lasers. This OFC, the field of optical modules, the major factories first show the CFP2 ACO module. ZTE's Dr. Jia Zhensen told us that this is the new standard just introduced, so the manufacturers are very important. The concept of the so-called ACO is to take the DSP part out of the module, so it can be done even less. Fujitsu, Finisar,nel, Oclaro and others have done a live dynamic display.

In the case of NEL, the company carried out a 20 km of CFP2 ACO to CFP2 DCO module transmission site display. 100G QSFP28 (CWDM4 MSA) and 25G SFP28 are the main technologies exhibited by major optical module companies this year. Finisar, Avago, Source, AAOI, Colorchip and so on are the focus of the display of QSFP28. In the case of Solth, the only dynamic display they made at the scene was the 100G LR4 long-distance QSFP28 module. It is also this year's progress to be able to support long distances compared to QSFP28 just introduced for short-distance applications last year. Finisar launched the QSFP28 module, which boasts the industry's first 2 km CWDM. Major domestic companies such as the Ultimate Hing Tong, Asahi Chuang, New Yi Sheng, hisense, Optical Xun also have a static display. The ultimate manager of Hing Tong Sun told the editor that their QSFP28 module would be officially shipped in the three quarter. The SFP28 module, paired with QSFP28, pioneered Oclaro's 10-kilometer module live display. Finisar on display is the SR version of the SFP28 module.
