Two-transmitting one-receiving optical component and assembling method thereof

Abstract

The invention discloses a two-transmitting one-receiving optical component and an assembling method thereof. The optical component includes an optical fiber adapter and a support; the optical fiber adapter is assembled on the support, so that optical signals transmitted from a first laser transmitter of the optical component are coupled into optical fibers of the optical fiber adapter; and an included angle of a center shaft and a horizontal shaft of the optical fiber adapter is a theta angle. The optical signals transmitted by the first laser transmitter of the two-transmitting on-receiving optical component provided by an embodiment of the invention are coupled into the optical fibers of the optical fiber adapter which is inclined at a theta angle, thereby enabling the optical signals that enter the optical fibers to be transmitted along the center shaft of the optical fiber as far as possible, thus increasing light receiving energy of the optical fiber adapter to the optical signals transmitted by the first laser transmitter, and improving coupling efficiency of the optical component.

Description

technical field [0001] The invention relates to the technical field of optical fiber communication, in particular to a two-emitting-one-receiving component and an assembly method thereof. Background technique [0002] At present, EPON (Ethernet Passive Optical Network, Ethernet Passive Optical Network) OLT (Optical Line Terminal, Optical Line Terminal) optical module needs to integrate two transmission channels and one reception channel, and the corresponding three-way optical device is called two transmission one Lighting components. [0003] The optical signal emitted by the existing laser transmitter is coupled at the oblique end face of the adapter ferrule and enters the optical fiber of the adapter. When refraction occurs due to different media, the optical signal entering the adapter fiber deviates from the central axis of the fiber, resulting in low coupling efficiency. [0004] In order to make the direction of the optical signal entering the optical fiber as close...
