Prior Art The present invention relates to an improved graded refractive index (GI) polymer optical fiber (POF) and a method for manufacturing the improved GI POF. Typically, the ‘1 0/1 00’ Ethernet local area network (“LAN”) is connected using a twisted pair category (“Cat”) 3/5 cable. Although Cat 3/5 cabling is effective for LAN connection, it is still far from being the perfect solution. For Ethernet 10/100 speeds, Cat 3/5 cabling is sufficient. However, to upgrade to Gigabit Ethernet, network managers will need to replace Cat 5 cabling with fiber optics. In addition, all the twisted-pair cables are susceptible to RF interference, which will limit their applicability in noisy RF environments. A transmission layer solution to the cable's bandwidth and RF restrictions is to replace glass cable (GOF) or plastic optical fiber (POF) with cable. Although GOF offers much better optical transmission properties than POF, it is not commercially practical for most LANs (<150 meters) with a large number of connections due to the high connection costs associated with terminating glass fibers. . Cutting and capping GOF is expensive for many reasons. A typical Gof, such as a 50/125 multitype fiber or a 10/125 monotype fiber, has a very small diameter and is brittle. The relatively small diameter of G0F requires the angle of incident light to be tightly controlled. In order to closely control the angle of incident light entering the fiber, it is necessary to carefully cut the fiber 200306250 (2) Description sheet of the invention and insert it into a precise connector. Therefore, special tools, trained technicians, and expensive and sophisticated connectors are required to end GOF. In a desktop environment where a local network needs to be quickly removed and connected, it makes the connection cost of GOF quite expensive. POF offers many of the advantages of GOF, namely the higher data rate supported by copper cables compared to curved windings, and no RF interference, but it does not have the 咼 link cost associated with GOF. Relative to the diameter of GOF, POF typically has an extremely large diameter-about 1 mm. This larger diameter allows lower connector tolerances without loss of optical coupling efficiency, and does not require the amber polishing steps required to end the GOF. The POF can be terminated by an untrained person using a hot plate. In addition, POF connection can use low-cost 500-800 nm 1ED. POF can be characterized by its radial refractive index. In the step index, the orientation index is basically a step function. In the graded index (i) POF, the radial index is the highest in the center of the fiber, and it decreases non-linearly with increasing radius. SI p0I ^ iGi p0F is cheap, but due to its inherent morphological dispersion, it is generally ineffective for higher speed data linking. For high-speed applications, GIP0F is preferred. Various manufacturers of various graded refractive index (GI) pomgi p0F have been developed. The second: IP0F includes a ring layer of multiple copolymers. See U.S. Patent = No. (992 patent). Regarding the present invention, the ring-shaped laminate of gip〇f --- privately as the heart or around the core in ⑺POF is characterized by different refractive indices. The polymer composition can make the refractive index into two: according to,- Contains many important limits == 200306250 (3) Description of the invention The polymer of each layer of the performance sheet is a macromolecule, so the polymer cannot easily diffuse between layers. Therefore, as indicated in Figure 1 of the 992 patent, the overall refractive index of pOF is not a smooth radial function, but is a series of step functions for each layer. Secondly, in order to avoid phase separation between layers and within layers, the composition of each layer is limited, so the range of refractive index is limited. In general, the more similar the chemical properties of the polymers that make up the copolymer, the more stable the copolymer is to phase separation. However, the more similar the two polymers are, the more similar their respective refractive indices are. Therefore, the 992 PO's GI POF has significant shortcomings; increasing the thermal stability of the POF will limit the range of refractive index. Two closely related GI POF systems consist of multiple annular layers, each of which contains multiple polymers. Japanese Published Patent Nos. 1309/4 and 86 and Japanese Published Patent No. 265208 / '89. According to these inventions, 2GI POF has the same deletions as the 992 application for the same reason. The polymer mixture constituting each layer tends to have a non-uniform structure due to micro or macroscopic phase separation, and therefore has a large scattering loss. Intrinsic loss of yttrium to GI poF, which is based on a variety of polymers, is an object of the present invention to a GI POF formed by a plurality of ring-shaped layers of a single polymer on the f substance. Another object of the present invention is an improved cyanine resin, wherein the radial refractive index can be changed without deteriorating the thermal stability of POF. Another aspect of the present invention: the objective is an improved GI model, in which the refractive index is closer to the smooth continuous function of the POF radius. Yet another object of the present invention is a POF with increased maximum bandwidth. The present invention is a method for manufacturing an improved G tool p 〇F, which is an improved technology for car-blocking technology. Summary of the Invention (4) (4) 200306250 Summary of Invention Summary page A specific embodiment of the present invention is a multilayer GI P0F Where each layer basically contains a polymer and one or more dopants. Each layer may contain the same or different polymers, although it is preferred that each layer contains the same homopolymer. Appropriate materials may be methacrylates, Formed by the polymerization of styrene, or monomers or prepolymers thereof. Useful dopants include cyclic or acyclic organic compounds, alkyl metal oxides or Rare earth alkyl oxide.

Figure-cross-sectional view and Figure lb is a longitudinal section. The POF according to the present invention includes multiple layers, and each layer may be characterized by its polymer / dopant concentration and its radial refractive index. Although FIG. 1 shows only three layers, the number of layers, fiber diameter, or fiber length of the ⑴PF according to the present invention is not necessarily limited. -In general, as the number of layers in ⑺Qing increases, the bandwidth and loss characteristics of &amp; GIPqf can be modified. The GI-POF according to the present invention may be from about 0.5 mm to about 2 mm, and preferably about 1 mm. -A given fiber may contain 3 to 3 () layers. For most 200306250 invention description pages (5) Optical transmission applications, including 10/10 Ethernet cable laying, 5-10 layer is sufficient. A preferred embodiment of the present invention includes five layers, the diameter of the center layer is about 0.25 mm, the thickness of the next three layers (second, third, and fourth layers) is about 0.075 mm, and the outer layer (Fifth layer) is about 0.15 mm. The GI POF may have a numerical aperture of about 0.01 to about 0.5. Lower numerical apertures cause bending loss and coupling loss. Higher numerical aperture limits the maximum bandwidth. Therefore, the preferred numerical aperture is between about 0.2 and about 0.3. If used, the retaining layer should be formed of a material with a lower refractive index than the outer layer to prevent scattering out of the fiber. In addition, the protective layer should be resistant to chemical and thermal degradation and also have a low coefficient of friction. Suitable layers for forming the protective layer include polymers and copolymers of tetrafluoroethylene such as Teflon PFA Teflon AF, and Teflon FEP. A preferred protective layer comprises a copolymer of 65%, 95% by weight of vinylidene difluoride and approximately Teflon AF by weight. The layers in the GI POF according to the present invention are preferably formed mainly of a polymer and one or more dopants. With regard to the present invention, a polymer is any compound formed by polymerizing a monomer or a prepolymer. By choosing the same homopolymer in each layer and changing the concentration of the impurity that changes the refractive index in each layer, phase separation within and between layers can be avoided. The advantage according to the present invention is that the dopant is used to adjust the refractive index of the substantially-homopolymer layer rather than the polymer to adjust the refractive index of each layer. In the GI POF according to the present invention, since each layer is basically a homopolymer composition, it is chemically similar to that of G! Q on a very small length scale. (6) 200306250 Invention Description Sheet For the solvation in liquid, the layers of GI pOF according to the present invention are similar to the solid state solvated solute. The polymer forms a "solvated shell" around the uniformly distributed doped ^ molecules. Therefore, the phase separation effect and interface scattering effect are reduced. In addition, since the dopant is relatively small with respect to the polymer chain system, and since the layers basically contain the same polymer, the dopant can easily diffuse in and between layers. The refractive indices can be matched. Those skilled in the art will know that when the concentration of the polymer is close to mono- or if the polymer of the site I has almost the same chemical properties, the chemical properties of the copolymer system will be close to the homopolymer system. Therefore, POF according to the present invention can also be formed by the following systems: υ copolymer system, such as a polymer system with a large excess (Mole stoichiometry &gt; 80%), or 2) a mixture of polymers, such as Similar chemical properties. Regarding GI pOF, the relevant chemical properties are the bulk density of each copolymer, the polymerization rate of each copolymer, and the bulk refractive index of each copolymer. -In general, the bulk density of each copolymer, the polymerization rate of each copolymer, and the refractive index of each copolymer should not change more than 3%, and should not (change more than 1.5% is better. Therefore, according to The 〇1 POF of the present invention can also be formed from a plurality of copolymer layers each containing one or more dopants as defined above. _ Skills / well-known polymers for constituting POF. Many can be used for construction The polymer system of POF uses the polymerization reaction of methacrylate, styrene or its respective derivatives. Since the use of 500-800 nanometer LEDs has a costly structure, ", i, but should be within 5⑼_ $ The optical absorption between 〇〇nm is reduced to a small value. The significant source of optical absorption at these frequencies is OH, CH, -11-200306250 ⑺ "--and nh bond vibration (all of which are polymerization Commonly owned) and styrene is the main material. In order to reduce the vibrational absorption of the end-capping bond, the substituents of q sense, such as the south atom, replace the chlorine atom. Substituting 4 elements to reduce absorption may also be unexpected Refractive Index of Substituted Polymers_Body Refractive Index of Polymers. For example, Substituting a fluorine atom for a propionate and a hydrogen atom in a styrene polymer tends to decrease the refractive index.

Stomach In the present invention, a dopant refers to any compound that is mixed with a polymer to adjust the refractive index of the resulting polymerized, heterogeneous agent combination to a higher or lower rate than the pure polymer. In general, the dopant should be a low molecular weight non-polymeric compound that will readily expand into the polymer matrix and is thermally stable at the polymer curing temperature. 2. Through selection, it can be easily diffused through the polymer-= of the heterogeneous agent 'to make the refractive index of a certain layer and the refractive index across two layers _ mountain knife. Refractive index concentration of special polymer / dopant system and its function -13- 200306250 (9) --- Description page of the invention 2. Function of special polymer and dopant. The refractive index of pure polymers can generally be added by adding a dopant that is larger than the organic groups that make up the polymer wood structure. Conversely, the discount of pure polymer can be reduced by adding a dopant that is smaller than the composition of the polymer. In addition, the appliance can be adjusted by applying an electric field, magnetic field, or lightning dopant to generate GIPOF, which is a function of the source of the changed refractive index. The refractive index in rhenium can be an external field or optical pumping. When the dopants include straight or branched chains with less than about 20 carbons, saturated =? :: cyclic or acyclic organic compounds. The replacement agent is only limited by its proper interaction with :: materials ... It is necessary to change the refractive index of the pure polymer, and it must be small enough :: to effectively diffuse throughout the polymer matrix during the formation of GI POF. Some that can be used to form the GIPOF according to the present invention: Miscellaneous agents include diphenyl phthalate, phenyl benzoate, bisphosphonate-benzyl sulfur,% benzyl-1-propanol, methacrylic acid_, Halogen-like compounds, such as brook benzene, M_dibenzyl, naphthol called trichlorobenzyl, o-dichlorobenzene, m-dichlorobenzene, I2 · dibromoethane, phthalic acid, sodium benzoate, cyclic bonds Such as difluorene, phenoxytoluene, diphenyl ether, bicyclization: such as biphenyl, diphenylsulfide, diphenyl methylbenzene '1.methoxyphenyl-i-phenylbenzene, and metal oxides and Rare earth alkyl oxide. . The dopant concentration in each layer may range from about 0 to about 30 weight percent of each layer. However, on the high side of the dopant concentration range, considering that special = dopants and polymers may be needed to reduce phase separation 'due to the relatively small size of the dopant molecule relative to the = compound chain, Concerns will be less than for copolymer systems with Aida copolymer concentrations. -14.

(: Zhiwen Zhengsha)) to maintain in the extrusion method Sufficient viscosity, so that the dopant can be completely diffused between layers and between adjacent layers. In order to make the refractive index at the interface between any two adjacent layers consistent, the adjacent layers are extruded.
