Embodiment Construction

[0034] 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.

[0035] 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.

[0036] The present invention can make the network wiring structure such as image 3 shown. and figure 1 Compared with it, the OTDR equipment and WDM are reduced, and the wiring difficulty and network cost of the PON system are reduced. For this reason, the present invention has two kinds of technical embodiments to illustrate.

[0037] One embodiment of the present invention adopts time-division multiplexing technology, and the functional ...

Abstract

The invention discloses an OLT (Optical Line Termination) optical module. The OLT optical module comprises an optical device, a PON (Passive Optical Network) data signal driver, a PON data signal limiting amplifier and an OTDR (Optical Time Domain Reflectometer) data processing module, wherein the optical device comprises WDM (Wavelength Division Multiplexing) which is dual-waveband WDM. By the invention, the cabling structure of a network can be simplified. Compared with the traditional network, the invention decreases OTDR equipment and WDM, reduces cabling cost and network cost of a PON system, and also lowers equipment and control complexity.

Description

technical field [0001] The invention relates to the fields of passive optical network (PON) and OTDR optical fiber testing, in particular to an OLT optical module integrating OTDR monitoring function. Background technique [0002] With the increasing demand for bandwidth of data services, these applications include high-definition IPTV broadcasting and multimedia distribution systems, etc., passive optical network access technology has been widely used. Passive optical network means that the ODN (Optical Distribution Network) does not contain any electronic devices and electronic power supplies. The ODN is composed of passive devices such as optical splitters (Splitter), and does not require expensive active electronic equipment. A passive optical network includes an optical line terminal (OLT) installed in a central control station, and a batch of supporting optical network units (ONUs) installed in user premises. The optical distribution network (ODN) between the OLT and ...
