KBJ806 is a high-performance, low-costoptical transceiver designed for data communications applications. It is one of Yangjie-3's standardized parts, a series of modular components developed to meet specific design requirements. The part has a small form factor, allowing it to be easily integrated into a variety of systems. It supports data rates up to 10Gbps and has a range up to 300m. It uses an 850nm VCSEL (Vertical Cavity Surface-Emitting Laser) and an APD (Avalanche Photodiode) for increased performance and low power consumption. The part is designed with a variety of features such as digital diagnostic monitoring, built-in over-temperature protection, remote power-down control, and more. It also complies with important industry standards such as GBIC, XFP, SFF and SFP.
