After splitting wiring box home store fiber coiled fiber optic cable splicing and leads to achieve straight-through cable capabilities to meet the needs of the traditional cable transmission network engineering branch box Introduction cable distribution box (Cable Distribution Box) is a method used to cabling implementation tap, branch connection and conversion circuit equipment, mostly for outdoor 2 cable distribution boxes of the type of cable distribution boxes divided into two categories according to their electrical constitution: one is free of any switching equipment , cabinets only be processed on the cable ends and connect accessories, the structure is simple, smaller, than a single function can be called ordinary distribution boxes; the other is the box not only has an attachment common distribution boxes further comprising one or more switching devices, its structure is more complex, larger, more connected devices, manufacturing technical difficulty, high cost, it can be called advanced distribution boxes. 1. Normal distribution boxes common distribution boxes No switching equipment within, into line with the outlet connected together electrically, the same potential, suitable for tap or branch wiring. It is customary to go back into the line number plus the number of outgoing called back the number of branches, for example three-branch cable distribution box It's on every phase has three other potential connection points can be used as one into two or two into one cable distribution boxes containing U, V, W three-phase, three-phase circuit same structure, along row together. 2. The High tap tap inside the box containing the advanced switching equipment, both from ordinary tap tap box, branch role, but also from the power supply circuit of control, conversion, and change the operation mode of action. Breaker The cable loop roughly divided into the line-side and the outlet side, both sides may not be the same as the potential switching device itself has a larger volume, so the advanced distribution boxes of relatively large dimensions, height is generally 1.4 ~ 1.8 m, depth of about of 0.9 ~ 1.0 m, length is according to the number of switching devices may be included, mostly between 1.0 m to 2.4 m. Case shape similar to outdoor box-type transformers, there are a number of activities on door enclosure, some door switch to operate the equipment and set up some doors for the installation construction or maintenance overhaul cable connecting devices of the word. 3 European and American cable distribution boxes difference of high voltage cable distribution box connector devices currently used, divided into two series of European and American. Continental device is to connect the cables concept Outdoor substation of the 1980s references imported from Europe to the field of cable distribution boxes, an American device sucked 90s from the United States of seat Line plug-in concept-mounted box-type substation references to cable distribution box Outside an insulation structure of the device different American conductor device has three rubber surrounds the innermost layer of semi-conductive shielding layer, an intermediate layer based insulation layers, the outermost of semi-permanent grounding conductor shield, so called shield type, price slightly higher. appearance of bread wrapped in two-story European-style device rubber, not the most external layer. 2, the concept of different devices Continental branch circuits connected in series branching, is about a number of silicone rubber insulation T-type device from the direction of the short arm of one after another in series to form the main loop and Branching out from the long arm of T pieces each Come. There are some disadvantages of this series branching: if a T piece branch road out of trouble, then this series components must be removed, removing the failed T member can continue to run after the re-string, once troubleshooting end, components need to come back a splitting and recombination, more trouble; the main circuit in series head more, affect the conductivity reliability, reduce dynamic stability; when the series components are more difficult to maintain the axis in the same line, causing some deviation from the normal position of the joint interface interfacial dielectric strength and ability will reduce water seepage. The American branch of the device is used in parallel mode, just overcome a series branch of the above disadvantages. Parallel branches are in isolation device distribution boxes of tank wall fixed a set (three phase) called busbars board, which play the role of busbars. Busbar board has a number of electrically connected in parallel to the outer cone seat, whether incoming, outgoing, branch lines, all connected to the bus bar cable board. Busbar plate inner conductor is silver solder, electrically conductive reliable, but the three phases separated by a little bigger, slightly more difficult with jumper cables, and a three-phase busbars plate lined the length of the box will grow in size. 3, with the surface of the conical taper taper with different European design according to German standards DIN47636 taper small; American taper is in accordance with US standards IEEE386 designed taper slightly. With different taper, will bring two of the following differences: different combinations along the surface of the insulating interface between (1) the strength of the device. Dielectric strength and its compression bonding interface rebound relationship exponential rise, silicone rubber with high elasticity, the weight, the higher the dielectric strength of more tightly. With taper greater repulsive force is large, the dielectric strength will be higher, so the American-style interface insulation strength of larger than Continental. (2) different water seepage capacity. With taper greater the weight of the rubber material interface tight, water seepage better the performance. Therefore, water seepage performance is slightly better than the European American devices devices. 4, the principle of distinction and American Continental device device (1) from the branch connector device structure, the parallel is the American branch of the series is the European branch. (2) from the insulating structure, the device has three rubber (inner shield, the main insulation layer, the outer shield) is an American, two-story rubber (inner shield, the main insulation layer) is European. For those devices on the outer surface of the second floor of the rubber layer by spraying method semiconductive film covering, since the installation or use of a thin layer of semiconducting susceptible to wear off, grounding performance is unreliable and can not be shielded, and should remain Continental device belongs. (3) the size of the device with the taper cone, not as a basis for discrimination. Because only geometry taper size problem involves only dielectric strength and anti-soaking ability colonel whether European or American insulation device, according to the United States with the taper can be standard or German standards for the design, so there will be an American with the United States and tapered, American band Europe cone, with Continental Europe with the United States and European tapered cone, such as different types of devices. Optical splitter, also known as splitter, is one of the important fiber link passive components, fiber optic tandem device having a plurality of inputs and a plurality of output terminals. Optical splitter can be divided according to the principle of splitting and flat-fused-tapered waveguide type (PLC type) two. Optical splitter structure can be divided according to the principle of splitting the melt and pull tapered planar waveguide type two, fused taper method is to two (or more than two) removing fiber coating to a certain way against interference in heated to high temperatures melted simultaneously stretched to both sides, a special form of a double cone waveguide structure eventually formed in the heating zone, by controlling the angle of the optical fiber twisting and stretching the length of the available different spectral ratio. Finally, the tapered region curing adhesive curing on a quartz substrate is inserted into the stainless steel brass, which is an optical splitter. This production process due to inconsistent curing adhesive thermal expansion coefficient of quartz, stainless steel pipe, the degree of change in the ambient temperature on the thermal expansion and contraction of inconsistencies, such a situation can easily lead optical splitter is damaged, especially the optical splitter The situation on the field even more, which is easily damaged optical splitter was the most important reason. For more splitters large ones can produce more than two splitter components. The PLC splitter using semiconductor technology (photolithography, etching, developing technology) production. Optical waveguide array on the surface of the chip, shunt function integrated on the chip, which is to achieve 1,1 and other branches on a chip; then, in the ends of the chip, respectively, and an output coupled to the input of multi-channel fiber array and package. Compared with Fused type splitter, PLC splitter advantages are: (1) Loss not sensitive to light wavelengths, to meet the needs of different transmission wavelengths. (2) the spectral uniformity can be evenly distributed to the user signal. Compact (3) structure, small size, can be installed directly in the various existing junction box, without leaving a large installation space. (4) single device bypass passage lot, it can reach 32 or more. (5) low cost multi-channel, the more points the large ones, more obvious cost advantage. Meanwhile, the main drawback PLC splitter are: (1) device fabrication process complexity, high technical threshold, currently monopolized by foreign several chip companies, domestic capable of high-volume packaging production companies rarely. (2) with respect to the higher melting pull cone splitter costs, particularly in the low channel splitter aspects more at a disadvantage. Fused cone principle product is the fusion of two or more fibers were made side; planar waveguide-type micro-optical components products, using photolithography techniques, the optical waveguide is formed on a dielectric or semiconductor substrate to achieve branch distribution function. This is similar to the two types of spectroscopic principle, their mutual coupling (coupling, coupling length) and changing the radius of the fiber-optic to achieve different sizes by varying the amount of branches between the evanescent field optical fiber, and vice versa may be combined into multiplexed optical signals along signal called a synthesizer. Fused fiber couplers due to the production method is simple, cheap, easy to connect with the external fiber into a whole, and can withstand mechanical vibration and temperature changes Corfu, etc., it has now become the mainstream manufacturing technology. And coaxial cable transmission systems, optical network systems need the optical signal coupling, branch distribution, which requires an optical splitter to achieve. Optical splitter used M × N to indicate a splitter has M inputs and N outputs. Optical splitter for use in optical fiber CATV systems are generally 1 × 2,1 × 3 and composed by them 1 × N optical splitter. Optical splitter for PON network formed by power distribution specifications, optical splitter can be expressed as M × N, also be expressed as M: N. M denotes an input optical fiber large ones, N represents the output optical fiber large ones. In FTTx systems, M may be 1 or 2, N for 2,4,8,16,32,64,128 like. The standard uniform is represented by M × N. Technical data loss: insertion loss of the optical splitter means each output relative to the input optical loss dB number, the mathematical expression is: Ai = -10lg Pouti / Pin, where Ai is the means to insert the i-th output ports loss; Pouti is the i-th output port optical power; Pin is the optical power input. Additional optical power loss is defined as the sum of all output ports with the input optical power loss DB number. It is worth mentioning that, for fiber optic couplers, additional losses are reflected in the device manufacturing process quality indicators, reflects the inherent loss of the device production process, this loss as small as possible, is to produce the quality of the merits of the assessment indicators. The insertion loss is only that the output power status of each output port, not only has the inherent loss of factors, but considering the effect of splitting ratio. Between the different fiber coupler, the insertion loss of the device making the difference and do not reflect the quality of the pros and cons. 1 * N for standard single-mode optical splitter additional losses in the following table: min large ones 2,345,678,910,111,216 additional losses DB 0.2 0.3 0.4 0.45 0.5 0.55 0.6 0.7 0.8 0.9 1.0 1.2 spectrophotometric ratio: splitting ratio is defined as the ratio of the output power of the optical splitter output ports in system application, the splitting ratio is indeed based on the number of actual system optical node optical power required to determine the appropriate split ratio (equal distribution except ), optical splitter splitting ratio related to the wavelength of light transmission, such as an optical splitter in the transmission of light at the two outputs of 1.31 m splitting ratio of 50:50; 1.5μm in the transmission of light, then becomes 70:30 (The reason this happens is because the optical splitter has a certain amount of bandwidth that the spectral bandwidth of the optical signal transmitted ratio unchanged). Therefore, when the optical splitter made sure to specify wavelength. Isolation refers to a light path optical splitter to other optical path of the optical signal isolation. In the above indicators, the isolation is more important significance for the optical splitter, in practical system applications often require isolation devices to reach more than 40dB, otherwise it will affect the performance of the entire system. Further optical splitter stability is also an important indicator, the so-called stability refers to external temperature changes, work changes in the state of other devices, optical splitter split ratio and other performance indicators should be essentially unchanged, In fact optical splitter stability depends entirely on the manufacturer's technological level, from different manufacturers, the quality gap is quite big. In practice, I also met a lot of really poor quality of the optical splitter, not only performance deteriorated quickly, and the failure rate is very high, an important device for optical fiber trunk, at the time of purchase must pay attention, not just look price, low technological level of the optical splitter price is certainly low. In addition, uniformity, return loss, directivity, PDL occupy a very important position in the optical splitter performance indicators. Packaging: optical splitter device package should cost-effective, robust and compact, the device inside the optical fiber should guarantee a certain radius of the disk fiber, optical fiber coiled guarantee against any damages, all devices should be fixed and can provide good enough for management, connection, installation, maintenance, inspection, testing space.
