New product release | SUNSTAR launch 50G Pon Combo OLT three -mode and optical device

With the scale of Gigabit broadband, 10G PON enters a large -scale deployment stage. At the same time, the industry is also deploying 50G PON to prepare for the era of the Wanzi era. Compared with 10G PON standards, the 50G PON standard can provide more than 5 times the access bandwidth, better business support capabilities (large bandwidth, low latency, high reliability), and the smooth evolution from GPON, 10G PON to 50G PON, And compatible with existing ODN networks as much as possible to protect the existing investment of operators. It is very important to support the compatibility of the three -mode compatibility and the Combo PON as a supplement, because operators have repeatedly stated that they do not want to interrupt the ODN network during the evolution of new technologies. new product release Sunstar first released 50G Pon Combo OLT three-mode and optical components (50G PON+XGS PON+GPON OLT), which meets the ITU-T G.9804.3 (2021) protocol standard. In QSFP and SFP modules, the optimized light road design meets better coupling efficiency indicators. This three -mode and optical device uses the ability of Guangheng to have mature packaging and manufacturing capabilities. From the overall metal structures, EML TO, DFB To, APD to, and OSA devices, they are all independently designed and processed by Sunstar. Product downlink wavelength: 50G 1342Nm EML, 10G 1577NM EML, 2.5G 1490Nm DFB; uplink wavelength: 25G 1286NM BM APD, 10G 1270Nm BM APD, 1.25G 1310Nm BM APD Company Profile Sunstar Communication Technology Co., Ltd. was established in 2001 with a registered capital of 40 million yuan and currently more than 1,000 employees. It is the industry's leading optical communication product manufacturer. Focus on the design and development, manufacturing, sales, technical support, optocoen modules of optoelectronic transceiver (OSA) and Optical Transceiver. After 20 years of technical accumulation and development, it has formed core technology design platforms such as light roads, mechanical structure, high -frequency simulation, thermal simulation, circuit, FPC soft board, and IT software automation. It has the vertical integration capabilities of the industrial chain from the optical chip BAR bar testing, cutting, and sorting, to-cap packaging, BOX device packaging, COB packaging, optical module packaging, optical fiber connector and precision optical machine processing component.
