Abstract: An optical multiplexer and a transmitter optical subassembly are provided that relate to the field of optics communications. A light-combining part is formed by using at least one light combiner that can combine two beams of light into one beam of light, and at least two levels of light-combining parts are used to constitute an optical multiplexer, so that 2N beams of light are combined into one beam by using N level of light-combining parts, thereby reducing a package size and packaging loss, and reducing the complexity of a manufacturing process.

Abstract: A single-fiber subassembly includes a first photodiode for receiving incident light, a laser diode for transmitting emergent light, and a same-wavelength optical splitter having a positive direction. The splitter includes a first birefringent plate, a half-wave plate, a 45° Faraday rotator, and a second birefringent plate arranged in sequence along and vertical to the positive direction. An included angle between an optical axis of the first plate and the positive direction is α, where 0°

Abstract: A method, device, and system for controlling network device auto-provisioning is provided. The method includes: acquiring network topology information that is in a live network and of a network device, where the network topology information includes an interface and an IP address of an uplink device directly connected to the network device. The method also includes detecting whether the network topology information in the live network matches preset network topology information; and if the network topology information in the live network matches the preset network topology information, sending, by a network management device to the network device, information about enabling the File Transfer Protocol (FTP) or Trivial FTP (TFTP), and an identifier of an operating system file and/or an identifier of a configuration file, so that the network device acquires the operating system file and/or the configuration file.

Abstract: Embodiments of the present invention relate to a bi-direction optical sub-assembly and an optical transceiver. A transmitter in the bi-direction optical sub-assembly is configured to transmit a first communication signal or a detection signal, where the first communication signal or the detection signal is input from a first end of a first optical path and output from a second end of the first optical path, enters a second end of a third optical path through reflection of a WDM optical filter, and is input from a first end of the third optical path to an optical fiber. A second communication signal received by the optical fiber is input from the first end of the third optical path and output from the second end of the third optical path, and the second signal is received by a BOSA receiver through transmission of the WDM optical filter.
