However the seal structure of FOSC in worldwide communication equipment market at present fails to prevent leakage of water effectively and therefore the quality of transmission greatly reduced. Because the OH- of water can destroy the O=SI=O structure of fiber and make the fiber core split. Judging from the current market, the products from big companies are very expensive, while the ones from small factories are not stable in seal performance. Although the unvulcanized rubber closure has a good performance in tractility, adhesive and compatibility, actually there are many disadvantages, as follows: 1. Seal performance may be affected caused by factitious factors, which it is difficult to check out. 2. Natural factors as follows: some unvulcanized rubber will be extruded from the closure because of expansion caused by heat in summer. 3. While in winter, it will be shrunk, therefore, the extruded part can t be reverted for lack of resilience, then it will split and affect seal performance as time goes on. 4. It will swing in bad weather like tempest then the connection area will be split because unvulcanized rubber is lack of elasticity.

3 5. Unvulcanized rubber is easy to be oxidized(aging) because of not being processed by vulcanized,and its life-span will be greatly reduced. 6. The unvulcanized rubber is of high self-glutinosity, which will make it more difficult to reuse. 7. Most FOSC can not efficiently solve the problem of fixation of fibres in the fibre entries; therefore the seal performance will be affected. Compared with others, the cost/performance of our products is more competitive, the quality advantages of our products are as follows: 1. Perfect airproof performance: the airproof structure is state-patented. FOSC are pressurized up to 100Kpa and put into water,no air bubbles or no change of air pressure after 36 hours. 2. Perfect antioxidation performance: under the same testing conditions. The antioxidation period of unvulcanized rubber will only last 62.10min, while vulcanized rubber will last 85.01min. 3. After we have tested the sewage, we found that the proportion of buck is too high polycarbonate will be easily eroded by alkalescent matter or even be dissolved by chloride and aromatic compounds. So we choose import engineering plastic as case material. 4. Easy operation: don t need operators to lay the airproof seal, which will save much time and reduce the negative influence caused by factitious factors. 5. The airproof seal adopts vulcanized rubber: it won't stick together when used and can be reused. Therefore, the seal performance can be guaranteed and can save money for customers. 6. High suitability: suitable for single core and ribbon optic cables, can be installed as aerial, pipe-lined and direct-buried, which can greatly reduce reserve and storage and can bring convenience to maintenance. Technical Indexes (1) Environment condition: Environmental temperature:-40 ~+60 Atmospheric pressure: 70~106Kpa.

The shell of the directed buried FOSC can educe the pigtails used for detecting fiber connection. The shell can be installed with valve, which is used for puffing and checking the air pressure when we check the seal performance inside the FOSC. 2) Inner components a) Bracket:main component, which is used for supporting the inner structure; b) The emplacing device for fibers: used for storing connectors, protectors and spare fibers orderly; the length of the spare fibers should not be shorter than 1.6m and the curvature radius should not be less than

4 37.5mm; should provide recognizable mark for re-fusion and provide enough room for operation; adopts horizontal gliding type, the loose-leaf turning type, the standing-up type or the expanding type; c) Fiber fixing device: used for fixing fiber protective tube and fiber reinforced components; d) Electronic linking device: used for connecting, earthing or disconnecting metal components in the fiber cables. 3) Seal components: Used for sealing FOSC and parts between FOSC and fiber protective tube. The seal method of FOSC either adopts heat shrink method or mechanical method or both. a. Heat shrink method: sealed after heating the tubular or ribbon Poly (Ethylen) (PE) heat shrink material spread inside. b. Mechanical method: sealed in mechanical way using adhesives, insulfuration self-adhesives, and sulfuration rubber plasticene compounds. 4) Fiber protector Protect the connector with heat shrink protective case, protective nip, V-slot rubber (4) Material: All material used for FOSC are stable in their physical and chemical properties; all material are compatible with each other, fiber cable protective material as well as other material used in outside connection devices in order to avoid corrosion or other electric damages.
