Embodiment
Optical fiber communication have bandwidth, at a high speed, exempt from electromagnetic interference (EMI), radiationless, anti-eavesdrop, the multiple advantage such as safe and reliable.At present optical fiber communication medium has two kinds of silica fibre and plastic optical fibers, and wherein, plastic optical fiber can be divided into again SI plastic optical fiber and GI plastic optical fiber.
Silica fibre luminous point docking precision prescribed is high, needs professional instrument, technology to operate, and meanwhile, silica fibre is very responsive to vibration, high to application environmental requirement.SI plastic Optical Fiber Transmission distance is 100m only, at present can only be for " last hundred meters " engineering of fiber entering household.GI plastic optical fiber has overcome the shortcoming that silica fibre installation and maintenance cost is high and SI plastic Optical Fiber Transmission distance is short simultaneously, and still, GI plastic optical fiber production cost is high, is difficult to popularize.
The utility model, for the high defect of GI plastic optical fiber production cost, provides a kind of uni-core bidirectional plastic optical fiber system, in the mode of full duplex, communicates, and has saved nearly half plastic optical fiber production cost.
The uni-core bidirectional plastic optical fiber system that the utility model provides as shown in Figure 1, comprise a perfluor plastic optical fiber 101 and two plastic optical fibre connectors 100, plastic optical fibre connector 100 is tightly fixed on plastic optical fiber two ends, and plastic optical fiber connects the equipment with optical fiber interface by the lock pin in plastic optical fibre connector 100.In the present embodiment, selected perfluor plastic optical fiber 101 belongs to a kind of of GI plastic optical fiber.
Figure 2 shows that a kind of applied environment of uni-core bidirectional plastic optical fiber system, comprise two plastic optical fibre connectors 100, perfluor plastic optical fiber 101 and with the equipment 102 and 103 of optical fiber interface 121, wherein two plastic optical fibre connectors 100 and a perfluor plastic optical fiber 101 form uni-core bidirectional plastic optical fiber systems.Optical fiber interface 121 comprises a built-in plastic optical fiber transceiver module 1211, the lock pin 3 that plastic optical fibre connector 100 comprises is directly inserted on plastic optical fiber transceiver module 1211 by optical fiber interface 100, realizes the optical fiber communication of uni-core bidirectional plastic optical fiber system and equipment 102 and 103.While it should be noted that plastic optical fibre connector 100 assembling, must guarantee that fiber end face inserts port with lock pin 3 and flushes.The communication mode of this system is single core full duplex.In present embodiment, plastic optical fibre connector 100 used is different from the existing quartz plastic joints of optical fibre and SI plastic optical fiber plastic optical fibre connector used, but the improved plastic optical fibre connector that is applicable to GI plastic optical fiber, this type of plastic optical fibre connector is all with the lock pin of a hollow-core construction, and lock pin diameter of bore is 1.0mm, this diameter for GI plastic optical fiber designs.
The utility model utilization list core system is realized two-way communication, so plastic optical fiber transceiver module 1211 comprises luminescence unit and light receiving unit simultaneously, be that equipment 102 and 103 receive plastic optical fiber with plastic fiber interface 121 the plastic optical fiber transceiver module 1211 that simultaneously comprises luminescence unit and light receiving unit, utilize same perfluor plastic optical fiber 101 to realize the transmitting-receiving of light signal, realize full-duplex communication.Now, for guaranteeing that the light signal that different directions is propagated does not produce interference, both should work in different wavelength, the luminescence unit that is same equipment is different with the wavelength that receives light with light receiving unit emission of light, the luminescence unit of another being connected equipment and the operation wavelength of light receiving unit and its cross-matched.For example, the luminescence unit emission of light of equipment 102 is 850nm, and it is 1330nm that light receiving unit receives light, and the luminescence unit emission of light of equipment 103 is 1330nm, and it is 850nm that light receiving unit receives light.Luminescence unit emission of light is not affected by the light signal in plastic optical fiber, but light receiving unit receives plastic optical fiber and propagates the light signal of coming, owing to there being the light signal of two kinds of wavelength in plastic optical fiber, for guaranteeing that light receiving unit receives light signal accurately, between the light receiving unit at plastic optical fiber two ends and plastic optical fiber, need to arrange an optical filtering.For example the light receiving unit of equipment 102 reception light is 1330nm, and the light of an optical filtering elimination 850nm is set before light receiving unit.
During concrete enforcement, plastic optical fiber transceiver module 1211 can adopt the fiber optical transceiver of based semiconductor laser technique, transceiving integrated to realize.Plastic optical fibre connector 100 can be OptoLock connectorless system or the interface that matches with the connector of SMI type or LC type or SC type or SC-RJ type.
Perfluor plastic optical fiber is a kind of novel plastic optical fiber, and the FONTEX that the AGC of take produces is representative.FONTEX is the pioneering optical fiber that can carry out the communication of 10 gigabits (Gbps) per second Large Volume Data in the world, compare with existing silica fibre, have and can under bending, rolled state, keep the feature of communication, even with within the family, suffer from and trample because of carelessness or bending etc., still very safe, relieved.The feature that FONTEX carrying capacity of environment is low, has reduced installation and maintenance cost.FONTEX power consumption is few, lightweight, simultaneously, at aspects such as transfer rate, power consumption, antinoise and flexibility, also there is significant advantage, the most important thing is that FONTEX has overcome the short shortcoming of common plastics Optical Fiber Transmission distance, has realized the optical communication of the long distance of two-forty.Table 1 and table 2 are used respectively different fiber transceiver, the comparison that transmission range when SI plastic optical fiber (SI POF), common GI plastic optical fiber (GI POF) and FONTEX are adopted to different transmission rates and loss are done.

Table 2 adopts VCSEL(665nm).
By table 1 and table 2, can be found out, FONTEX is under identical transfer rate, its transmission range is greater than SI plastic optical fiber and common GI plastic optical fiber, especially when high-speed transfer, while being 1Gbps as transfer rate, the transmission range of FONTEX is the decades of times of SI plastic optical fiber, the several times of common GI plastic optical fiber, and loss be not more than common GI plastic optical fiber; And while adopting compared with low transmission rate, while being 100Mbps or 10Mbps as transfer rate, the transmission range of FONTEX is only than about SI plastic optical fiber and the long 100m of common GI plastic optical fiber, its loss is very nearly the same also.The manufacturing cost of considering FONTEX is that (market price FONTEX is 4 yuan every meter for the several times of common GI plastic optical fiber and SI plastic optical fiber, 2 yuan every meter of common GI plastic optical fiber, 0.8 yuan every meter of SI plastic optical fiber), FONTEX is applicable to remote optical fiber communication.
The FONTEX theoretical transmission rate limit is 10Gbps * 100m, but according to the material characteristic of FONTEX, is expected to further improve transfer rate.Fig. 3 is the FONTEX transmission potentiality of inferring from material dispersity, visible, hundred meters of transmission ranges, and in the visible-range of 350～770nm, transfer rate increases along with the increase of optical wavelength, and its maximal value runs far deeper than 10Gbps.
