Abstract

An embodiment of the present invention provides a light-emitting device, including a base, a laser, an optical receiver, and a filter; the filter is provided with a splitting surface, the base includes a table, the optical receiver and the filter Placed on the table, and the filter is arranged obliquely relative to the table, the laser is located on the side of the filter that is provided with the split-wave surface, and the optical receiver is located on the side of the filter that is away from One side of the laser, and the filter shields the receiving light port of the optical receiver, the optical receiver receives the light transmitted through the filter, and the light emitted by the laser is reflected by the sub-wave surface , and the included angle between the optical axis of the light emitted by the laser and the normal line of the subwave surface is less than 45 degrees. The invention also provides an optical module and communication equipment.

Description

technical field [0001] The invention relates to the technical field of optical communication, in particular to a transceiver light device, an optical module and communication equipment. Background technique [0002] In the optical communication system, the optical module is mainly used to realize photoelectric and electro-optical conversion, that is, convert the transmitted data signal into an optical signal and send it to the opposite end through the optical fiber, and receive the optical signal sent by the opposite end through the optical fiber and convert the optical signal After the electrical signal is generated, the received data is resumed from the electrical signal. The existing bidirectional optical components for optical modules integrate the original receiver, laser, amplifier and other components into one package, the transmitting part and receiving part share a package and coupling lens, and the transmitting light and receiving light pass through a 45 Filters a...
