Embodiment Construction

[0018] All features disclosed in this specification, or steps in all methods or processes disclosed, may be combined in any manner, except for mutually exclusive features and / or steps.

[0019] Any feature disclosed in this specification (including any appended claims, abstract and drawings), unless expressly stated otherwise, may be replaced by alternative features which are equivalent or serve a similar purpose. That is, unless expressly stated otherwise, each feature is one example only of a series of equivalent or similar features.

[0020] In the implementation case of the present invention, it can be divided into two parts of the circuit, one part is the same as the common ONT photoelectric conversion optical module (in the dotted line box), including the optical transceiver (BOSA), the laser driver (LDD), and the limiting amplifier (LA) and main control unit (MCU). The optical transmitter has a built-in backlight current detection, and the laser driver monitors the lum...

Abstract

The invention discloses a passive optical network terminal which relates to the Ethernet passive optical network (EPON) technology. The novel passive optical network terminal integrates a photoelectric conversion circuit of a common optical network terminal and an MAC protocol processing circuit of the passive optical network into an SFP package. The self-contained MAC Ethernet passive optical network terminal SFP is characterized by comprising an optical transceiver BOSA (1), a laser driver LDD (3-1), a limiting amplifier LA (3-2), a PON protocol chip and peripheral circuit (4), an Ethernet serial parallel conversion chip SERDES (5), and a control unit MCU (2). The invention mainly protects the idea of integrating a common photoelectric conversion optical module and a PONMAC chip in the SFP package and realizes the circuit.

Description

technical field [0001] The invention discloses a passive optical network terminal related to the Ethernet passive optical network (EPON) technology. This new type of passive optical network terminal combines the photoelectric conversion circuit of the ordinary optical network terminal The processing circuitry is integrated into an SFP package. Background technique [0002] With the increasing demand for bandwidth of data services, these applications include high-definition IPTV broadcasting and multimedia distribution systems, etc., EPON technology has been widely used. main application structure figure 1 As shown, the OLT at the central office is respectively connected to the ONT box through an optical splitter, and the ONT box provides a network port or an optical fiber interface according to the requirements of the user switch. The user switch is designed with an SFP socket, which can be inserted into an electrical port SFP or a photoelectric conversion SFP module. [...
