Bi-directional Optical Sub-Assemblies (BOSA) are essential components in optical networking, enabling simultaneous transmission and reception of data over a single fiber, commonly used in high-speed data communication applications. These products feature varying laser and photodetector configurations, such as 25G and 50G data rates with DFB or EML lasers paired with PD or APD photodetectors. Notable suppliers like Friend Laser Photonics Co.,Ltd. provide these sophisticated assemblies. On FindLight, buyers can compare technical specifications, request pricing, and connect directly with manufacturers without the need for registration.
