The module is characterized by comprising an interface unit (01), a speed rate conversion unit (02), a control unit (03), an emission unit (04), a receiving unit (05) and a power supply unit (06), wherein the control unit (03) is connected with the emission unit (04) and the receiving unit (05); the power supply unit (06) is connected with the interface unit (01), the emission unit (04), the receiving unit (05) and the control unit (03); and a reference clock of the speed rate conversion unit (02) is a crystal oscillator with two fixed frequency points. By adopting the technical scheme provided by the invention, the speed rate conversion part adopts a frequency synthesizer chip capable of providing two fixed frequencies, and thus the 100G CFP optical module can be used for an OUT (optical transform unit) 4 system which is suitable for 103.1235Gbps Ethernet and 111.874Gbps Ethernet.
Description
Technical field
The present invention relates to optical communication field, be specifically related to a kind of 100G CFP optical module of supporting two different rates.
Background technology
Along with the development of information technology and people demand to the communication broadband; Communications field transmission capacity is growing; Traditional transmission technology has been difficult to satisfy the requirement of transmission capacity and transmission speed; In the data center field and fields such as internet core on-line shops, search engine, high-performance computer, cloud computing, for the broadband resource that prevents network occurs not enoughly, common carrier and service providers dispose express network agreement of new generation.IEEE mainly formulates the network interface and the Ethernet correlation map standard of user side, has issued 40G/100G Ethernet interface standard 802.3ba; OIF is responsible to define 100G line side optical module standard, comprises protocol specifications such as receiver/transmitter module, forward error correction technique, module machinery electrical characteristic; ITU-T mainly formulates the carrier network relevant criterion, and the current ODU4/OTU4 relevant issues of having accomplished discusses.
But CFP is the packing forms by standard in the multi-source agreement of the initiation of internationally recognizable optical module manufacturer of several families and 40G that formulates and 100G plug optical module.Yet, because the client is different to the demand in professional broadband, having good compatibility in order to make optical module, the optical module of different rates satisfies client's demand so equipment vendor need provide support.At present; 100G CFP is used for satisfying the Ethernet transmission requirement with 103.125Gbps; Yet individual customer also requires to satisfy the 111.809974Gpbs of OTU4; So compatibility and versatility in order to realize module, a kind of 100G optical module of two fixed rates of supporting just seems particularly important.
Summary of the invention
The purpose of this invention is to provide a kind of optical module that can support two different rates, can satisfy the 103.125Gbps of Ethernet and the 111.809974Gpbs of OTU4, increased the flexibility and the versatility of optical module adaptive system.
The present invention provides a kind of 100G CFP optical module of supporting two kinds of speed, and it comprises: interface unit 01, rate transition unit 02, control unit 03, transmitter unit 04, receiving element 05 and power supply unit 06; Wherein, said control unit 03 is connected with transmitter unit 04, receiving element 05; Said power supply unit 06 is connected with interface unit 01, transmitter unit 04, receiving element 05 and control unit 03; The reference clock of said rate transition unit 02 is to have two fixedly crystal oscillators of frequency.
Technique effect of the present invention is; The rate transition of the 100G CFP optical module of two kinds of speed of support of the present invention has partly adopted the synthesizer chip that two fixed frequencies can be provided; Make 100G CFP optical module can be fit to the OTU4 system of 103.1235Gbps Ethernet and 111.874Gbps at the same time; Increase the versatility of 100G CFP optical module like this, can effectively reduce the cost that the system of equipment vendor is switched; In addition because the 100G CFP among the present invention only supports two fixed frequencies, thus its Billy to reach stable speed with the module of self-adaptation clock adjustment faster, and can reduce cost.
Other features and advantages of the present invention will be set forth in specification subsequently, and, partly from specification, become obvious, perhaps understand through embodiment of the present invention.The object of the invention can be realized through the structure that in the specification of being write, claims and accompanying drawing, is particularly pointed out and obtained with other advantages.
Through accompanying drawing and embodiment, technical scheme of the present invention is done further detailed description below.
Description of drawings
Accompanying drawing is used to provide further understanding of the present invention, and constitutes the part of specification, is used to explain the present invention with embodiments of the invention, is not construed as limiting the invention.In the accompanying drawings:
Fig. 1 is the structured flowchart of the specific embodiment of the invention one.
Wherein, interface unit 01, rate transition unit 02, control unit 03, transmitter unit 04, receiving element 05, power supply unit 06.
Embodiment
Below in conjunction with accompanying drawing the preferred embodiments of the present invention are described, should be appreciated that preferred embodiment described herein only is used for explanation and explains the present invention, and be not used in qualification the present invention.
Below will combine Figure of description, describe the present invention in detail.
As shown in Figure 1, the 100G CFP optical module of two fixed rates of support of the present invention mainly comprises interface unit 01, rate transition unit 02, control unit 03, transmitter unit 04, receiving element 05 and power supply unit 06.
Wherein rate transition part 02 main rate transition, the timing and data reproduction function that realizes the signal of telecommunication; Control unit 03 is connected with transmitter unit 04, receiving element 05, realizes communicating with host computer and each parameter being carried out can only controlling and carrying out supervision and reporting; Transmitter unit 04 mainly is through emitting module (TOSA) electrical signal conversion to be become light signal output, utilizes wave multiplexer that 4 wavelength optical signals are exported then; It is 4 light signals that wavelength is different that receiving element 05 adopts channel-splitting filter will receive conversion of signals, accomplishes the electric light conversion through 4 groups of optical fiber receive modules (ROSA) again; It is that transmitter unit 04, receiving element 05, control unit 03 provide the power supply input that power supply unit 06 obtains input voltage from interface unit 01, and controls the open and close of each functional unit.Wherein in order to realize that 100G CFP optical module supports two fixed rates, the present invention the reference clock of rate transition part adopt have two fixedly the crystal oscillator of frequency come reference clock to be provided to GEARBOX so that the input data utilize clock synchronization to recover.
Technique effect of the present invention is; The rate transition of the 100G CFP optical module of two kinds of speed of support of the present invention has partly adopted the synthesizer chip that two fixed frequencies can be provided; Make 100G CFP optical module can be fit to the OTU4 system of 103.1235Gbps Ethernet and 111.874Gbps at the same time; Increase the versatility of 100G CFP optical module like this, can effectively reduce the cost that the system of equipment vendor is switched; In addition because the 100G CFP among the present invention only supports two fixed frequencies, thus its Billy to reach stable speed with the module of self-adaptation clock adjustment faster, and can reduce cost.
