Problems solved by technology

[0005] The purpose of the embodiment of the present invention is to provide a dual-optical transceiver device to solve the problem that the traditional active components based on collimated optical paths and the curing method of the optical interface in the prior art need to use the "glue process", which leads to high and low temperature performance of the device. Poor structure reliability and stability cannot be guaranteed, etc. This traditional collimated light process seriously restricts the mass production of this dual optical port transceiver device

Abstract

The invention is applicable to the field of optical communication and provides a double-optical-port transceiving device. The double-optical-port transceiving device comprises a transmitting assembly, a receiving assembly, a pipe body assembly, a microprism filtering assembly, a first adaptor assembly and a second adaptor assembly. The double-optical-port transceiving device is characterized in that the receiving assembly is located at one end of the pipe body assembly, the transmitting assembly is located at one side of the pipe body assembly, and the first adaptor assembly and the second adaptor assembly are located at the other side of the pipe body assembly in parallel; the second adaptor assembly is close to one end of the receiving assembly, and the axis line of the first adaptor assembly and the axis line of the transmitting assembly are located in the same straight line; a first connector which is arranged on the pipe body assembly and used for being connected with the first adaptor assembly and a second connector which is arranged on the pipe body assembly and used for being connected with the second adaptor assembly are arranged at a high position and a low position respectively. According to the double-optical-port transceiving device, the defects that in the prior art, since the heights of connectors are identical, a laser point needs to be blocked when the connectors on the same side are welded, and welding of the same side faces of two pins can not be adjusted in the welding adjusting process are overcome through the high-low position method.

Description

technical field [0001] The invention belongs to the field of optical communication, and in particular relates to a transceiver device with dual optical ports. Background technique [0002] With the deepening of network applications such as transmission, access and data, higher and higher requirements are put forward for the integration of network equipment functions. A low-cost integration solution is to cascade in the existing network architecture. Integrate the required functional units. For example, on the side of the access network (Optical Line Terminal, abbreviated as: OLT), the optical fiber fault location (Optical Time Domain Reflectometer, abbreviated as: OTDR) function is integrated, and for example in the access network (Optical Network Unit, abbreviated as: ONU) side integration can realize analog signal return reflection (RF over Glass, abbreviated as: RFoG) function, etc. In view of the requirements of the above three major networks integrating specific netwo...
