Embodiment
As shown in Figure 1, the related plastic optical fiber kilowatt meter reading-out system of the utility model comprises terminal gauging table 1, concentrator 2 and data processing centre (DPC) 3; Terminal gauging table 1 and concentrator 2 be with plastic fiber interface, between transmission medium be plastic optical fiber 4.Described plastic optical fiber kilowatt meter reading-out system, signal flow to and to be: terminal gauging table 1 image data, be sent to concentrator 2, and concentrator 2 can carry out simple process to the data that receive, and is sent to data processing centre (DPC) 3 and unifies to process.
Figure 2 shows that described plastic fiber interface synoptic diagram, plastic optical fiber continues by plastic fiber interface.Plastic fiber interface 10 comprises a built-in plastic optical fiber transceiver module 101.Plastic optical fiber transceiver module 101 is the fiber optical transceiver based on RCLED technology or VCSEL technology, comprises a light-receiving chip 1011 and a light transmitting chip 1012, such as the fiber optical transceiver of FIRECOMMS company.Be different from the existing 850/1310/1550(nm of working in) the silica fibre transceiver module of wavelength, the operation wavelength that plastic optical fiber transceiver module 101 described in the utility model adopts is visible light.Plastic optical fiber transceiver module 101 also can be based on other model fiber optical transceivers of Distributed Feedback Laser technology or FP laser technique.Plastic fiber interface 10 is OptoLock connectorless system or the interface that matches with the connector of SMI type or LC type or SC type or SC-RJ type.Plastic optical fiber directly inserts in the plastic optical fiber transceiver module 101 by plastic fiber interface 10.
The related plastic optical fiber of the utility model can be SI plastic optical fiber, also can be GI plastic optical fiber, and it is different that the two key distinction is that core-Skin index distributes.
SI plastic optical fiber full name is step-refraction index (step index) profile plastic optical fiber, has obvious core-Pi interface, the refractive index of plastic optical fiber is undergone mutation at core-Pi interface, namely the core refractive index of plastic optical fiber is n1 in core diameter, cortex refractive index in the cortex sudden change is n2, and n1〉n2.Total reflection occurs at core-Pi interface in incident light, and the transmission of light in fibre core relies on this total reflection to advance with serrate.Because the incident angle of incident light is different, causes each mould light to arrive the asynchronism(-nization) of receiver, and the pulse strenching phenomenon occurs.Under the limited condition of broadening, the incident angle of the incident light of SI plastic Optical Fiber Transmission is limited, causes its Bandwidth-Constrained.
GI plastic optical fiber full name is graded index (graded index) profile plastic optical fiber, and when light transmitted in GI plastic optical fiber, refractive index reduced gradually from axle center to edge, radially is para-curve and changes.Because the refractive index of GI-POF no longer is a constant, make each mould light transmission speed therein different, and the time of their arrival receivers is almost identical, output pulse strenching is little, so the bandwidth of GI-POF is more much bigger than SI-POF.
Terminal gauging table described in the utility model can be ammeter, water meter, gas meter, other consumption gauging table or Multifunctional measuring table.
