Embodiment Construction

[0018] It should be understood at the outset that, although an illustrative implementation of one or more embodiments is provided below, the disclosed systems and / or methods may be implemented using any number of techniques, whether currently known or in existence. The invention should in no way be limited to the illustrative implementations, drawings, and techniques illustrated below, including the exemplary designs and implementations illustrated and described herein, but rather be within the scope of the appended claims and their equivalents Modified within the full range of .

[0019] The transceiver in an optical line terminal (optical line terminal, OLT for short) or an optical network unit (optical network unit, ONU for short) of the PON usually includes a BOSA. A traditional BOSA uses two TO-packages, one TO-package contains the transmitter and the other TO-package contains the receiver. In this BOSA, there is no crosstalk between the transmitted signal and the receiv...

Abstract

An optical transceiver comprises a transmitter (209) and a receiver (212) housed in a transistor outline (TO) can. The receiver (212) comprises a first submount (241) comprising at least one waveguide(282, 284, 286, 288, 290, 292 ), a photodiode (236) coupled to the first submount (241) and the at least one waveguide (282, 284, 286, 288, 290, 292 ), and a transimpedance amplifier (TIA) (239) coupled to the first submount (241) and the at least one waveguide (282, 284, 286, 288, 290, 292), wherein the at least waveguide (282, 284, 286, 288, 290, 292) couples the photodiode (236) to the TIA (239), wherein the at least one waveguide (282, 284, 286, 288, 290, 292) is positioned on the first submount (241) in between the photodiode (236) and the TIA (239).

Description

[0001] Related Applications Cross Application [0002] This application claims prior application priority to U.S. Nonprovisional Application No. 15 / 497,427, filed April 26, 2017, entitled "Transistor Outline (TO) Packaged Optical Transceiver," which was claimed on April 26, 2016 Priority and benefit of U.S. Provisional Patent Application No. 62 / 328,696, filed by NingCheng on 28th, entitled "Transistor Outline (TO) Packaged Optical Transceiver", the contents of which are reproduced by way of incorporation Incorporated into this article. Background technique [0003] An optical transceiver is a device capable of sending and receiving optical signals. Optical transceivers have many applications, including use in passive optical networks (PON). Optical transceivers may include optical and electrical components. These components can be integrated in an integrated chip. A plurality of such integrated chips may form a system package (system inpackage, SIP for short). In optoelec...
