Description

可接取相同及相異波長的光纖網路訊號接取模組Optical fiber network signal access module that can access the same and different wavelengths

本新型係關於一種光纖網路訊號接取模組的技術領域,尤指一種可接取相同及相異波長的光纖網路訊號接取模組。 The present invention relates to the technical field of an optical fiber network signal access module, in particular to an optical fiber network signal access module capable of accessing the same and different wavelengths.

光纖是一種由玻璃或塑料製成的纖維,利用光在這些纖維中以全反射原理傳輸的光傳導工具,其具有速度快、容量高、安全性佳、損耗小、重量輕、成本低等優點,因此於現今已普遍用於網路訊號之傳輸。 Optical fiber is a kind of fiber made of glass or plastic. It is a light transmission tool that uses the principle of total reflection to transmit light in these fibers. It has the advantages of high speed, high capacity, good safety, low loss, light weight, and low cost. , so it has been widely used in the transmission of network signals.

於光纖網路訊號傳輸中,可將光纖的工作波長分割成多個通道,例如80個通道,故能在同一條光纖內傳輸更大量的資料,舉例而言,電信公司利用同一條光纖就可以同時傳遞電話、網際網路、有線電視的訊號。由於同一條光纖內之不同的光訊號會分別具有不同的波長,故必須利用波長分波多工器(Wavelength Division Multiplexing,WDM)分離不同的波長。 In optical fiber network signal transmission, the working wavelength of the optical fiber can be divided into multiple channels, such as 80 channels, so that a larger amount of data can be transmitted in the same optical fiber. For example, a telecommunications company can use the same optical fiber to Simultaneous transmission of telephone, Internet, cable TV signals. Since different optical signals in the same optical fiber have different wavelengths, a wavelength division multiplexer (Wavelength Division Multiplexing, WDM) must be used to separate the different wavelengths.

請參照圖1,其係為習知光纖網路訊號接取模組之架構圖,其係揭示於美國專利案第5,629,995號。如圖1所示,習知光纖網路訊號接取模組9包含第一波長分波多工器91、第二波長分波多工器92、及放大器93、94,波長λ1的光訊號由第一波長分波多工器91之共同埠(Common Port)911進入,因為波長分波多工器A之過濾元件914係設計為能讓波長λ1的光訊號通過,故波長λ1的光訊號能通過過濾元件914並由透射埠(Pass Port)913輸出,之後,波長λ1的光訊號經由放大器94(增加訊號強度避免訊號衰減)並由第二波長分波多工器92之共同埠921進入,因為第二波長分波多工器92之過濾元件924係設計為不能讓波長λ1的光訊號通過,故波長λ1的光訊號會由過濾元件924反射至反射埠(Reflect Port)922輸出。反之,波長λ2的光訊號由第二波長分波多工器92之反射埠922進入並通過過濾元件924(過濾元件924係設計為能讓波長λ2的光訊號通過)而由透射埠923輸出,之後經由放大器93再由第一波長分波多工器91之反 射埠912進入,然後再由過濾元件914反射至共同埠911(過濾元件914係設計為不能讓波長λ2的光訊號通過)輸出。 Please refer to FIG. 1 , which is a structural diagram of a conventional optical fiber network signal access module disclosed in US Patent No. 5,629,995. As shown in Figure 1, the conventional optical fiber network signal access module 9 includes a first wavelength division multiplexer 91, a second wavelength division multiplexer 92, and amplifiers 93, 94, and the optical signal of wavelength λ1 is transmitted by the first The common port (Common Port) 911 of the wavelength division multiplexer 91 enters, because the filter element 914 of the wavelength division multiplexer A is designed to allow the optical signal of the wavelength λ1 to pass through, so the optical signal of the wavelength λ1 can pass through the filter element 914 And output by the transmission port (Pass Port) 913, after that, the optical signal of the wavelength λ1 passes through the amplifier 94 (to increase the signal strength to avoid signal attenuation) and enters by the common port 921 of the second wavelength division multiplexer 92, because the second wavelength division The filter element 924 of the multiplexer 92 is designed not to allow the optical signal of the wavelength λ1 to pass through, so the optical signal of the wavelength λ1 will be reflected by the filter element 924 to the reflection port (Reflect Port) 922 for output. On the contrary, the optical signal of wavelength λ2 enters through the reflection port 922 of the second wavelength division multiplexer 92 and passes through the filter element 924 (the filter element 924 is designed to allow the optical signal of wavelength λ2 to pass through) and is output by the transmission port 923, and then Through the amplifier 93 and then by the reverse of the first wavelength division multiplexer 91 The emission port 912 enters, and then is reflected by the filter element 914 to the output of the common port 911 (the filter element 914 is designed not to allow the optical signal of wavelength λ2 to pass through).

由上述可知,因為波長分波多工器之特性,即其過濾元件係設計為僅能讓某特定波長之光訊號通過,因此,圖1所示之應用架構僅能接取(Add/Drop)(即所謂加入/擷取)不同波長的光訊號,亦即僅能擷取λ1(λ2)/加入λ2(λ1),無法滿足現今光纖通訊的需求。 It can be seen from the above that because of the characteristics of the wavelength division multiplexer, that is, its filter element is designed to only allow optical signals of a certain wavelength to pass through, therefore, the application architecture shown in Figure 1 can only access (Add/Drop) ( That is, the so-called addition/extraction) of optical signals of different wavelengths, that is, only λ1 (λ2)/addition of λ2 (λ1) can be extracted, which cannot meet the requirements of today's optical fiber communication.

為了解決上述習知光纖網路訊號接取模組僅能接取不同波長的訊號之問題,本新型係提出一種改變架構設計的光纖網路訊號接取模組,其可接取相同及相異波長的光纖網路訊號,增加使用上的彈性。 In order to solve the above-mentioned problem that the conventional optical fiber network signal access module can only receive signals of different wavelengths, this new model proposes a fiber optic network signal access module with a changed architecture design, which can receive the same and different signals. Optical fiber network signals with different wavelengths increase the flexibility of use.

根據本新型,提供了一種可接取相同及相異波長的光纖網路訊號接取模組,包括一第一波長分波多工器、一第二波長分波多工器以及一第一光循環器。其中,該第一波長分波多工器包括一第一共同埠、一第一反射埠、一第一透射埠及一第一過濾元件,該第一共同埠係以該第一過濾元件之反射作用而訊號連通於該第一反射埠,該第一共同埠係以該第一過濾元件之通過作用而訊號連通於該第一透射埠;該第二波長分波多工器係連通於該第一波長分波多工器,且該第二波長分波多工器包括一第二共同埠、一第二反射埠、一第二透射埠及一第二過濾元件,該第二共同埠係以該第二過濾元件之反射作用而訊號連通於該第二反射埠,該第二共同埠係以該第二過濾元件之通過作用而訊號連通於該第二透射埠,其中,可通過該第二過濾元件之光訊號的波長與可通過該第一過濾元件之光訊號的波長相同或不相同;該第一光循環器包括三個第一通訊埠,該三個第一通訊埠之其中一者係連通於該第一透射埠與該第二透射埠之其中一者。 According to the present invention, an optical fiber network signal access module capable of accessing the same and different wavelengths is provided, including a first wavelength division multiplexer, a second wavelength division multiplexer and a first optical circulator . Wherein, the first wavelength division multiplexer includes a first common port, a first reflection port, a first transmission port and a first filter element, and the first common port is based on the reflection effect of the first filter element And the signal is connected to the first reflection port, the first common port is connected to the first transmission port by the passing function of the first filter element; the second wavelength division multiplexer is connected to the first wavelength A wavelength division multiplexer, and the second wavelength division multiplexer includes a second common port, a second reflection port, a second transmission port and a second filter element, and the second common port is filtered by the second The signal is connected to the second reflection port by the reflection of the component, and the second common port is connected to the second transmission port by the passing function of the second filter element, wherein the light that can pass through the second filter element The wavelength of the signal is the same as or different from the wavelength of the optical signal that can pass through the first filter element; the first optical circulator includes three first communication ports, and one of the three first communication ports is connected to the One of the first transmission port and the second transmission port.

於上述本新型所提出之可接取相同及相異波長的光纖網路訊號接取模組中,係加入使用光循環器(Circulator),而所謂光循環器是一種具有三個(或四個)通訊埠的光學設備,其可將光訊號依循一定的方向由一個通訊埠傳輸到下一個通訊埠,例如,當具有某一波長的光訊號由第一個通訊埠入射進入光循環器後,會從第二個通訊埠輸出,又當某一波長的光訊號由第二個通訊埠入射進入光循環器後,會從第三個通訊埠輸出,形成由第一個通訊埠至第 二個通訊埠、第二個通訊埠至第三個通訊埠的光訊號傳輸路徑;換言之,當某一波長的光訊號被反射時,其不會回到原本的通訊埠,而是會由另一個通訊埠輸出,故光循環器可被使用於分離在光纖中沿相反方向傳輸的光訊號,達到於單一根光纖上雙向傳輸之目的。因此,相較於習知之光纖網路訊號接取模組僅能接取相異波長之光訊號而言,本新型藉由利用光循環器而可接取相同及相異波長的光訊號,相對地可提高使用上的彈性。 In the optical fiber network signal access module proposed by the above-mentioned new model that can access the same and different wavelengths, an optical circulator (Circulator) is added, and the so-called optical circulator is a kind of optical circulator with three (or four) ) optical device of the communication port, which can transmit the optical signal from one communication port to the next communication port in a certain direction, for example, when the optical signal with a certain wavelength enters the optical circulator from the first communication port, It will be output from the second communication port, and when the optical signal of a certain wavelength enters the optical circulator from the second communication port, it will be output from the third communication port, forming a channel from the first communication port to the second communication port. Two communication ports, the optical signal transmission path from the second communication port to the third communication port; in other words, when an optical signal of a certain wavelength is reflected, it will not return to the original communication port, but will be transmitted by another One communication port output, so the optical circulator can be used to separate the optical signal transmitted in the opposite direction in the optical fiber, so as to achieve the purpose of bidirectional transmission on a single optical fiber. Therefore, compared to the conventional optical fiber network signal access module which can only receive optical signals of different wavelengths, the new model can receive optical signals of the same and different wavelengths by using an optical circulator. It can improve the flexibility of use.

以下詳細說明相同波長之光訊號的傳輸過程。如圖2所示,光纖21所載之不同波長λ1、λ2、λ3、λ4...的光訊號經由第一波長分波多工器11之第一共同埠111進入第一波長分波多工器11後,由於第一波長分波多工器11之第一過濾元件114(例如濾片,利用各波長的反射率與透射率的不同將不同波長之光訊號分工解出)係設計為僅能讓波長λ1的光訊號通過,其它波長λ2、λ3、λ4...的光訊號無法通過第一過濾元件114而受到反射。 The transmission process of optical signals of the same wavelength is described in detail below. As shown in Figure 2, the optical signals of different wavelengths λ1, λ2, λ3, λ4... carried by the optical fiber 21 enter the first wavelength division multiplexer 11 through the first common port 111 of the first wavelength division multiplexer 11 Afterwards, since the first filter element 114 of the first wavelength division multiplexer 11 (such as a filter, utilizes the difference in the reflectivity and transmittance of each wavelength to divide and solve the optical signals of different wavelengths) is designed to only allow wavelength The optical signal of λ1 passes through, and the optical signals of other wavelengths λ2, λ3, λ4, . . . cannot pass through the first filter element 114 and are reflected.
