Description
Technical field
The present invention relates to be used for erbium-doped fiber amplifier (Erbium Doped Fiber Amplifier-EDFA), specifically a kind of miniature fiber amplifier of Optical Transmission Network OTN.
Background technology
Fiber amplifier is the revolutionary product of communication industry development, and it is widely used in fields such as optical communication, optical-fiber network, cable TV and national defence, is the new industry of 21 century.Fiber amplifier comprises doped optical fibre amplifier, fiber nonlinear effect amplifier etc.; It is the Primary Component in the optical transmission; Wherein (Erbium Doped Fiber Amplifier-EDFA) utilize Er-doped fiber that light signal is directly amplified has thoroughly eradicated the electronics " bottleneck " that forms in traditional photoelectric repeater to erbium-doped fiber amplifier; Because of it has that gain is high, noise is low, power is big, working band is wide, polarization irrelevant, channel interference are little, to good characteristics such as transmission code rate and form and system upgrade are transparent; Be the desired light amplifier in the high speed fibre transmission network, wavelength division multiplexing (WDM) transmission technology becomes the most effectively means of current realization two-forty, high-capacity optical fiber communication because of the support of EDFA.
Along with modern communication is fast-developing, the Optical Transmission Network OTN 40G transmission system of a new generation, increasingly high to the overall volume requirement of fiber amplifier (EDFA).At present common EDFA overall dimension is bigger mostly, and stock size is 130 * 180 * 20mm; The miniaturization EDFA module overall dimension of MSA agreement regulation is: 90 * 70 * 15mm.The 40G optical transmission system of a new generation is 60 * 40 * 15mm to the shape requirement of EDFA, and is little more a lot of than at present common EDFA overall dimension, even compare also half as large many with the small-sized EDFA overall dimensions of MSA agreement regulation; Therefore the miniaturization EDFA of development a new generation challenges to circuit, light path, mechanical structure: mentality of designing, the components and parts that must overturn original conventional EDFA are selected principle for use, and all are prerequisite with minimum dimension, the minimum profile that satisfies performance.
Summary of the invention
The present invention is directed to the problems referred to above, the miniature fiber amplifier of the desired minimum profile size of a kind of satisfied transmission network 40G transmission system of new generation is provided.
According to technical scheme of the present invention: a kind of miniature fiber amplifier; Comprise housing and be arranged in circuit devcie and the light path devices in the said housing; Said housing is made up of upper cover plate, module base and lower cover, and the middle part of said module base is provided with dividing plate, and said dividing plate is divided into two spaces up and down with said module base; Be furnished with said light path devices in the said last space, be furnished with said circuit devcie in the said following space.
The vertical consistency of the vertical and said module base of said light path devices.
Said circuit devcie comprises printed circuit board (PCB), and said printed circuit board (PCB) is furnished with laser, photodetector and electrical interface on a side of said lower cover, and said laser and said electrical interface parallel longitudinal are arranged, said photodetector transverse arrangement of turbo.
Said laser adopts 8 pins not have the serial pumping of refrigeration.
Said printed circuit board (PCB) adopts the design of 6 laminates, presses the order of top layer, bus plane, first internal layer, second internal layer, stratum and bottom and arranges.
Technique effect of the present invention is: the present invention is divided into two spaces through dividing plate with the housing of amplifier; Light path devices and circuit devcie layering are placed; Can optimize the interior layout of product; Reduce the bulk of product, make product satisfy the requirement of transmission network 40G transmission system of new generation, its overall dimension only has 60 * 40 * 15 mm.
Description of drawings
Fig. 1 is a decomposition texture sketch map of the present invention.
Fig. 2 is a cross sectional view of the present invention.
Embodiment
Be further described below in conjunction with the accompanying drawing specific embodiments of the invention.
Among Fig. 1, Fig. 2, comprise upper cover plate 1, light path devices 2, module base 3, printed circuit board (PCB) 4, photodetector 5, laser 6, electrical interface 7, lower cover 8, dividing plate 9 etc.
Like Fig. 1, shown in Figure 2, the present invention is a kind of miniature fiber amplifier, comprises housing and is arranged in circuit devcie and the light path devices 2 in the housing.
Housing is made up of upper cover plate 1, module base 3 and lower cover 8, and upper cover plate 1 and lower cover 8 pass through screw respectively on module base 3.The overall dimension of housing only has 60 * 40 * 15 mm, can satisfy the shape requirement of the 40G optical transmission system of a new generation to EDFA.
In order to realize the miniaturization of amplifier, entire product has adopted hierarchical design, and promptly light path layer and device layer separate.Be provided with dividing plate 9 at the middle part of module base 3, dividing plate 9 is divided into two spaces up and down with module base 3.Be furnished with light path devices 2 in the last space, the vertical consistency of the vertical and module base 3 of light path devices 2; Be furnished with circuit devcie in the following space.Such design is not disturbed in the production debug process in later stage mutually, can not interact in the time of change circuit or light path devices.
Circuit devcie comprises printed circuit board (PCB) 4, and printed circuit board (PCB) 4 faces down and is furnished with laser 6, photodetector 5 and electrical interface 7 on the side of cover plate 8, and laser 6 and electrical interface 7 parallel longitudinals are arranged, photodetector 5 transverse arrangement of turbo.In order to reduce bulk, the device that is adopted is all selected microdevice for use.
Because power output of the present invention is not very big, and because the overall dimension of module only has 60 * 40 * 15 mm, can only select small-sized nothing refrigeration pumping, laser 6 adopts 8 pins not have the serial pumping of refrigeration.Because it is less that product heats when operate as normal, the heat radiation aspect does not have problem, can satisfy the requirement of product reliability.
At printed circuit board (PCB) (PCB) 4 design aspects, adopt the square patch of device, as much as possible reduce the PCB size; Analog circuit, digital circuit are concentrated relatively according to function respectively and are placed on the layout, avoid the interference effect of numerical portion to analog circuit, especially avoid the detection influence to input, output flashlight.Because the square paster of device, fabric swatch density is higher, and especially artificial circuit part, so PCB adopts the design of 6 laminates, presses the order of top layer, bus plane, first internal layer, second internal layer, stratum and bottom and arranges.
The present invention is divided into two spaces through dividing plate 9 with the housing of amplifier; Light path devices 2 and circuit devcie layering are placed; Can optimize the interior layout of product; Reduce the bulk of product, make product satisfy the requirement of transmission network 40G transmission system of new generation, its overall dimension only has 60 * 40 * 15 mm.
