The full name of BOB is BOSA On Board. BOB is a technical solution and production process of “breaking the whole into parts”. The BOB solution makes the circuit board design of home terminals more flexible, helps to reduce the terminal volume, and facilitates home installation and placement. With the rapid development of home information networks, people’s demand for network speed is increasing, and the emergence of BOB technology provides a good solution for the development of fiber optic network access technology. After adopting BOB technology, Optical Cat differs from traditional Optical Cat in the packaging method of optical modules. The optical modules are directly welded to the ONU board, simplifying the product structure, reducing product costs, and improving product quality.
The application of BOB technology is increasing nowadays, which can improve the system integration density without increasing too much cost, which brings a great impetus to increase the capacity and reduce the cost of optical communication systems. With the widespread application of BOB technology in EPON/GPON ONU device terminals, it has basically replaced the independent optical module scheme, becoming an important symbol of the rapid development and large-scale mature deployment of FTTH terminals.
