Abstract
A bidirectional transmitting and receiving device for the connection of optical fiber is mainly to apply one side of a T shape shell to connect an optical fiber, while another side of the shell in line with the optical fiber is arranged an optical transmitter, with an optical receiver being arranged at the third side of the shell, wherein the optical transmitter is a packaging structure of Transistor Outline can (TO-can) having a cup shape lid, of which underside is inclined 45 degrees to transmitted light beam, and wherein a hollow window in the underside of the lid is arranged a light splitting filter, which is just positioned at the beam path of the optical receiver.
Claims5
A bi-directional optical signal transmitting and receiving device for connecting an optical fiber of bi-directional transmission, comprising:
- a shell having two straight-through sides and a third side, wherein the optical fiber is connected to one of the straight-through sides;
- an optical transmitter including a base seat and a light-emitting component, arranged at another one of the straight-through sides of the shell and in line with a beam path directed between the light-emitting component and the optical fiber the optical transmitter having a Transistor Outline can (TO-can) structure with an indented lid mounted on the base seat to enclose the light-emitting component therein, wherein the indented lid comprises an underside being inclined 45 degrees to the beam path and a light splitting filter is arranged on the underside with a focusing lens facing the light-emitting component formed thereon to make light beam emitted from the light-emitting component be more concentrated;
- and
- an optical receiver;
- arranged at the third side of the shell and in corresponding to the light splitting filter,
- wherein the light beam emitted from the light-emitting component passes through the light splitting filter and enters the optical fiber while light beam coming from the optical fiber is reflected vertically toward the optical receiver via reflection of light splitting filter.
