Abstract: An adjustable micro-optoelectronic system supporting bidirectional transmission, an online upgrade, and online configuration. The system includes: a substrate; and edge connectors, a clock-and-data recovery (CDR) chip for transmitting, a CDR chip for receiving, a microprocessor, and an internal optical system, which are provided on the substrate. The edge connectors serve as an interface of a high-speed electrical signal, and are configured to exchange information between the micro-optoelectronic system and an external environment. The internal optical system is configured to transmit and receive an optical signal. A link for the high-speed electrical signal is connected among the edge connectors, the CDR chip for transmitting, the internal optical system, and the CDR chip for receiving. A communication connection is provided between the microprocessor and each of the edge connectors, the CDR chip for transmitting, the CDR chip for receiving, and the internal optical system.

Abstract: A single-fiber bidirectional optical transceiver subassembly, related to technology of optical communications, including an optical transmitting subassembly, an optical receiving subassembly and an optical splitting and filtering unit. The optical transmitting subassembly is coupled with an optical input port of the optical splitting and filtering unit. The optical receiving subassembly is coupled with an optical output port of the optical splitting and filtering unit. A bidirectional port of the optical splitting and filtering unit is coupled with a single-mode fiber. Each optical element in the optical transmitting subassembly, the optical receiving subassembly, and the optical splitting and filtering unit is a spatial optical element. Single-fiber bidirectional transmission is implemented with small channel spacing, by improving the optical splitting and filtering unit.
