Mitsubishi Electric's four new products are preparing for the 5g market, leading the Gigabit broadband era
With the near end of the domestic optical device destocking, the smooth evolution of FTTH from GPON to XGPON/XGSPON, and the increase in capital expenditure of domestic operators in the 5G cycle, the domestic optical device market demand is expected to accelerate.
Recently, the 20th China International Optoelectronic Exposition CIOE2018 will be held at the Shenzhen Convention and Exhibition Center. As a professional exhibition covering the entire photoelectric industry chain, CIOE has become the platform of choice for many enterprises to expand and promote their products.
At the exhibition, Mitsubishi Electric will exhibit 25 optical components, and highlight four new high-power 10GEMLTOCAN, commercial-grade 25GDFBTOCAN, 25GEMLTOCAN, 100G integrated EMLTOSA four new optical devices, the latest products high-power 10GEMLTOCAN and 25GEMLTOCAN It was the first appearance at the exhibition.
With the 4K/8K image transmission and the popularity of VR, Gigabit Broadband is being realized through China Telecom, China Mobile and China Unicom. And 10GPON is the key to achieving Gigabit broadband, and the speed should be increased to 10Gb/s. For the ITU-T standard, it is upgraded from G-PON to XG-PON/XGS-PON.
However, the problem has also arisen. Since ITU-T is based on running on a separate network when developing XG-PON, it does not consider how to be compatible with the already-installed G-PON network, so how to be compatible with G-PON and XG-PON problem.
To this end, the industry has proposed two solutions: WDM-PON and Combo-PON. The WDM-PON solution is to combine G-PON and XG-PON with external WDM couplers and then place them in the same network. However, because the operator needs to connect the coupler outside the OLT, improper connection and difficulty will occur. Maintenance issues.
The Combo-PON method puts all the functions of G-PON and XG-PON in the same transceiver module, so it is necessary to place four active optical devices at the same time, and the total power consumption will exceed 3.0W, among which the most critical 10G1577nmEML is more High power output is required. Mitsubishi Electric has developed Combo-PON (SFP+) high-output and low-power EML-TO-CAN through a variety of technologies, and provides aspherical lens type. The flat-window type supports various device designs for G-- Contribute to the coexistence and popularity of PON and XG-PON.

On the other hand, in order to cope with the growing demand for broadband communication networks, and actively preparing for the 5G commercialization market in China, which will come in 2020, Mitsubishi Electric is actively developing miniaturized and low-power optical communication devices.
Undoubtedly, in the 5G mobile base station network, the optical components required from the pre-transmission, the intermediate transmission to the back-transmission are higher than the current 4G. For the high bandwidth required by 5G wireless networks, Mitsubishi Electric has various high-speed optical devices from 25G to 100G to prepare for the future 5G mobile base station network.
