Description
Technical Field
The invention belongs to the technical field of optical fiber communication and optical transceiving modules, and particularly relates to an optical fiber-to-the-home mixed transmission optical transceiving module.
Background
With The increasing popularity of optical fiber networks, especially The gradual implementation of fiber To The home (ftth) project around The world and point-To-point data transmission, there is an increasing demand in The market for single-fiber bidirectional components capable of realizing multiple-path transceiving communication via multi-wavelength laser coupling in a single optical fiber in order To reasonably utilize The distributed optical fiber resources. Particularly, with the advance of triple-play and the upgrade of fiber-to-the-home networks from EPONs and GPONs to next-generation fiber-to-the-home networks (XGPONs), hybrid networking is occurring, and the market demand for single-fiber four-way components is increasing, especially for two single-fiber four-way components with narrow wavelength intervals.
Many operators choose upgrading and transformation from GPON to XG-PON1 to deal with the increasingly urgent bandwidth pressure. The traditional upgrading scheme is an external wave combination accelerating scheme as shown in the attached drawing 1 of the specification, a GPON optical module (102) and an XGPON optical module (103) adopt an external wavelength division multiplexing device WDM1r (302), and optical signals of the GPON (102) and the XGPON (103) are combined into the same ODN network through an external WDM1r (302), but the external wave combination accelerating scheme needs to be additionally provided with a plurality of facilities, such as an XG-PON1OLT machine frame, an XG-PON1 line card, a cabinet, an external wave combination device and related machine room supporting facilities, so that the upgrading scheme has the series problems of high construction cost, large machine room space occupation, complex optical fiber wiring, difficult operation and maintenance and the like.
For example, in the XGPON standard, the wavelength to be processed is 1270nm and 1577nm, compared with 1310nm and 1490nm in the original GPON standard and 1550nm in the triple-play, the wavelength interval is changed from original narrowest 60nm to narrowest 27 nm. The actual transition band is changed from 40nm to 15nm, and the corresponding technical difficulty is multiplied.
For example, in a single-fiber four-wavelength component in a QSFP (Quad Small Form-factor plug module) standard, the wavelength interval of 1270nm, 1290nm, 1310nm, 1330nm and the like to be processed is 20nm, and the actual transition band is changed from original 40nm to within 10nm, so that the corresponding technical difficulty is multiplied.
For example, a single fiber four-wavelength component in the CFP (Compact Form-factor plug) standard has a wavelength interval of 3.2nm/400GHz to be processed, and this time, it is completely impossible to solve the problem with a common filter scheme.
While solving the problem of single-fiber multi-directional components, the practical application scene also puts requirements on the external dimension of the components, and the external dimension of the components is further reduced from the external dimension of a standard XFP module to the external dimension of a standard SFP module. SFP (Small Form-factor plug) is a miniaturized, hot-pluggable optical transceiver module. The basic function of the photoelectric signal conversion device is to realize photoelectric signal conversion in signal transmission. The SFP packaging module has the characteristics of small volume, simple structure, hot plug and the like, and has great advantages in the aspects of maintenance and upgrading of a communication system. Many models of optical module products are therefore prone to SFP packaged modules.
As shown in fig. 2 in the specification, a first optical signal and a second optical signal enter an optical assembly from a common end 500 through an optical fiber, in the optical assembly, a first optical filter 601 forms an angle of 45 degrees with an optical path, a light beam passes through the first optical filter 601, and the first optical signal is reflected by 90 degrees and received by a first photodetector 501; the second optical signal is transmitted by the first optical filter 601, then passes through the second optical filter 602, and then is reflected by the second optical filter 602 and received by the second photodetector 502. The first receiving terminal 501 and the second receiving terminal 502 are photodetectors for performing photoelectric conversion, so that optical signals are converted into electrical signals. The first emitting end 503 and the second emitting end 504 are laser diodes, a third optical signal emitted by the first emitting end 503 is transmitted into the common end 500 through the third optical filter 603, the second optical filter 602 and the first optical filter 601, and a fourth optical signal emitted by the second emitting end 504 is reflected by the third optical filter 603 and then transmitted into the common end 500 through the second optical filter 602 and the first optical filter 601.
In this structure, since the third filters 603 of the first filter 601 and the second filter 602 must be incident at 45 ° to achieve transmission and reflection of different wavelengths, the four wavelength intervals of the transmitting end and the receiving end must be wide enough to meet the application requirement, otherwise the transmitted wavelength signals or the reflected wavelength signals cannot be effectively separated. When the wavelengths of the two optical signals input from the common terminal are closely spaced, the first filter 601 and the second filter 602 cannot effectively separate the two adjacent wavelengths.
In the application requirement, the transmitted optical signals are converted into parallel beams, and the four optical signals can be effectively separated, but the difficulty of light separation of the large-angle filter is high, the cost is high, and the optical index cannot completely meet the requirement.

The first optical transceiver component is used for transmitting a first optical signal lambda 1 and receiving a second optical signal lambda 2; the second optical transceiver module is used for transmitting a third optical signal lambda 3 and receiving a fourth optical signal lambda 4.

After the first optical signal λ 1 emitted by the first optical transceiver module 201 is output through the transmission end T of the wavelength division multiplexing module 301, because the first optical signal λ 1 is located in the transmission band of the wavelength division multiplexing module 301, the first optical signal λ 1 is output through the common end COM of the wavelength division multiplexing module 301 after being transmitted through the wavelength division multiplexing module 301. Since the second optical signal λ 2 input from the common end COM of the wavelength division multiplexing component 301 is located in the transmission waveband of the wavelength division multiplexing component 301, the second optical signal λ 2 is transmitted by the wavelength division multiplexing component 301 and then output from the transmission end T to the first optical transceiver component 201 for reception. After the third optical signal λ 3 emitted by the second optical transceiver module 202 is output through the reflection end R of the wavelength division multiplexing module 301, because the third optical signal λ 3 is located in the reflection band of the wavelength division multiplexing module 301, the third optical signal λ 3 is output through the common end COM of the wavelength division multiplexing module 301 after being reflected by the wavelength division multiplexing module 301. Since the fourth optical signal λ 4 input from the common port COM of the wavelength division multiplexing module 301 is located in the reflection band of the wavelength division multiplexing module 301, the fourth optical signal λ 4 is reflected by the wavelength division multiplexing module 301 and then output from the reflection port R to the second optical transceiver module 202 for reception. The first optical signal, the second optical signal, the third optical signal, and the fourth optical signal in this embodiment may be optical signals of arbitrary wavelengths.
