Problems solved by technology

[0004] The two-way optical signal transceiving device disclosed in each of the above-mentioned patents has the beam splitter as an independent component, which must be fixed in the housing through special positioning and packaging procedures, so its manufacturing process is relatively complicated and precise, which further reduces the manufacturing cost. Moreover, because the beam splitter requires such a sophisticated and complex processing procedure, it is difficult to reduce the volume of the housing, because the smaller the housing volume, the more unfavorable it is for the positioning and processing of the beam splitter

Embodiment Construction

[0022] The technical content and detailed description of the present invention are described as follows with the accompanying drawings:

[0023] image 3 It is a sectional view of the combination of the present invention. Such as image 3 As shown, the two-way optical signal transceiver 2 of the present invention mainly includes a T-shaped housing 21, an optical transmitter 22, and an optical receiver 23. One end of the two through ends of the housing 21 is coupled to the optical fiber 3 by a sleeve 24, and the light transmitter 22 is fixed on the other through end of the housing 21 so that the beam path emitted by the optical fiber is the same as the optical fiber. The light beam path of 3 is in a straight line; the light receiver 23 is fixed on the third end of the housing 21 so that the light beam path of the light receiver 23 is perpendicular to the light beam path between the optical fiber 3 and the light transmitter 22.

[0024] The light emitter 22 includes a base 220 and a...

Abstract

This invention relates to a two-way T / R device used in connecting fibers, in which, one end of T-shape shell is connected with the fiber and the other end in the same line with the fiber is set with an emitter and an optical receiver is set at the third end of the shell and in a transistor-like shell package structure (TO-can) including a cup-like cover, the bottom of which is in 45deg slant to the route of optical beams, and a spectroscope is set in the hollow window at the bottom and just set on the route of optical beams of the receiver.

Description

Technical field [0001] The present invention relates to an optical signal transceiving device, in particular to a light splitting type bidirectional transceiving device. Background technique [0002] Such as figure 1 with figure 2 As shown, the known two-way optical signal transceiver device 1 mainly combines an optical transmitter 11 and an optical receiver 12 in a T-shaped housing 10. One end of the housing 10 is combined with the optical fiber 13, and the light transmitter 11 and the light receiver 12 are respectively disposed on the remaining two ends of the housing 10. The light emitting and light receiving surfaces of the light transmitter 11 and the light receiver 12 are respectively provided with focusing lenses 15 and 16. In addition, a light splitting filter 14 is fixed at the intersection of the two beam paths between the light transmitter 11, the light receiver 12 and the optical fiber 13, and is connected to the two beam paths. At a 45 degree angle. The side of t...
