C114 News on December 29th (Nanshan) Today at the "All-Optical Home Seminar" held by China International Optoelectronics Expo (CIOE) and C114 Communication Network, Wu Kai, Deputy General Manager of HGZ Zhengyuan Intelligent Terminal Division, presented "FTTR Optical "Device Market Outlook and Development Discussion" gave a speech on the theme of "the value of optical devices, an important part of the commercialization of FTTR".As an important part of the optical access network, the performance and cost of optical components are important considerations for FTTR deployment.Wu Kai introduced that the deployment of FTTR will bring new demands for OLT BOSA and ONU BOSA; the change in product form of FTTR also requires optical devices to reduce costs and improve reliability.Based on the power budget requirements of FTTR networking, optical devices can be appropriately improved to reduce costs. The main optimization directions include: the main gateway downstream GPON OLT adopts BOB design, OLT BOSA adopts PIN detector, removes isolators, boost circuits and large light protection ; Reduce the transmit power, thereby improving the BOSA coupling efficiency and yield, and reducing the BOSA cost.Its core element is to promote the industry to formulate physical layer standards suitable for FTTR networks, reduce the cost of optical devices and even gateways, and create conditions for large-scale implementation.As a mainstream optical device supplier, HGZ Zhengyuan has the R&D and manufacturing capabilities of the entire industry chain from the design of the underlying optical chip to the optical device and optical module, and through the deployment of the wireless side, it creates a comprehensive solution of "optical connection + wireless connection" .Based on the evolution of FTTR and the demand for optical devices, HGZ Zhengyuan and its chip company Yunling Optoelectronics started from chips to create cost-effective optical device products.At the OLT central office, HGZ uses 1577 EML+SOA integrated chips to provide 40km E2 optical device solutions with high reliability, small size and low cost.
