With the popularization of gigabit broadband, 10G PON has entered the stage of large-scale deployment. At the same time, the industry is also laying out 50G PON to prepare for the 10-gigabit era. Compared with 10G PON, the 50G PON standard provides five times more access bandwidth and better service support capabilities (large bandwidth, low latency, and high reliability). At the same time, for operators, the biggest problem facing the commercial use of 50G PON is the problem of multi-generation coexistence. ITU-T standards provide different options for the differentiated deployment of global operators. GPON region, G.9804.1 Amd2 and G.9805 offer 2 classes /5 options; EPON area, provides 2 types /4 options. From this point of view, multi-generation coexistence is an inevitable choice in the continuous evolution of the next generation PON. Sunstar Communication Technology Co.,Ltd.released 50G PON three-mode Combo OLT miniaturized optical device, which is MPM (built-in combined wave) 3-generation wave division mode coexistence, that is, G/XG(S)/50G three-mode MPM. The advantage of this solution is that the traditional gateway devices can be reused without changing or upgrading the user side, and the upgrade process can be optimized, equipment occupation and equipment room space can be saved, and energy consumption can be reduced. This three-mode Combo OLT miniaturized optical device uses a novel optical path design and a miniaturized TO-CAN package solution, and uses the technology accumulation and quality control of Sunstar Company in the field of coaxial packaging for many years, combining precision manufacturing, multi-wavelength spectrographic design and various types of TO-CAN package technology perfectly together. The 50G PON three-mode Combo OLT compact optical device of Sunstar Company is characterized by small size, high coupling efficiency, high structural reliability and strong manufacturability in mass production. The most critical is that its optimized optical path design and special packaging process ensure the upstream three-wavelength splitting, especially the isolation index of 50G PON upstream wavelength and GPON upstream wavelength, that is, the isolation degree of 1286±2nm and 1310±20nm edge wavelength; And take into account the high coupling efficiency of the downgoing three-way emitting laser to ensure the best output optical power index. This optical device is fully suitable for SFP and QSFP module packages, helping the access network to smoothly evolve to 50G PON. The 49th Optical Networking and Communications Symposium and Expo (OFC 2024) will be held from March 26 to 28, 2024 at the San Diego Convention Center, California, USA. The company will bring 10G PON OLT, 25G PON OLT, 50G PON OLT three-mode, 400G ER4 TOSA & ROSA, 800G DR8 optical module and a full range of AOC optical module solutions to the exhibition, welcome to visit the #3841 booth.
