What is the difference between optical fiber fusion and cold! Optical fiber cold joint used in optical fiber butt fiber or fiber butt end fiber, this is equivalent to do joint, Fiber tail docking fiber refers to dock with the tail fiber in the fiber core optical fiber instead of the former said tail fiber head) For this kind of thing called optical cold subgroups. Optical fiber cold subgroups is used when two tail fiber butt, principal components inside it is a fine v-groove, after two tail fiber dial fiber using cold subgroups to complete two tail fiber. He operate more brief quickly, than with welding machine welding save time. Cold through there are always two ways: first, to the scene quickly linker; The second kind of optical fiber butt cold subgroups. With the rapid development of FTTH fiber to the home, the demand for optical fiber cold subgroups also increased greatly. Optical fiber connector quickly with optical cold subgroups in FTTH access performance no substitution effect, optical fiber connectors immediately termination skills just solve this difficult problem, without welding operation convenient and quick, low in cost, true complete access anytime and anywhere. Used for fiber butt fiber or fiber butt end fiber, this is equivalent to do joint, Fiber tail docking fiber refers to dock with the tail fiber in the fiber core optical fiber instead of the former said tail fiber head) For this kind of thing called optical cold subgroups. Optical fiber cold subgroups is used when two tail fiber butt, principal components inside it is a fine v-groove, after two tail fiber dial fiber using cold subgroups to complete two tail fiber. He operate more brief quickly, than with welding machine welding save time. Cable welding cable welding is a detailed work, especially in the preparation, welding, pan fiber end face, request the operator observe carefully, careful thinking, operation specification. Light in the optical fiber transmission loss happens, the loss is the first by the transmission loss of optical fiber itself and the loss of fiber of welding joint. Cable once order, its basic determine the transmission loss of optical fiber itself, and loss of fiber of welding joint is related to fiber itself and site construction. Try our best to reduce the loss of fiber of welding joint, can increase the fiber optic repeater expand transmission distance and the attenuation of optical fiber link margin. Difference of cold joint and the welding hot melt needs using the welding machine, optical fiber cutting knife. Will pick up two optical fibers, don't need other auxiliary materials. Advantages are stable quality and low in consumption, About 0. 3 to 0. 05) 。 Disadvantage is high cost of equipment, equipment, storage capacity is limited. Fieldwork love constraints. Cold does not demand too much equipment, optical fiber cutting knife. But each contact demand a quick connector ( To say the future main operation) 。 About 5 to 10 yuan. The advantage is easy to operation, the appropriate field. Big drawback loss. About 0. 1 to 0. 2 db each point. Cold subgroups 'can directly produce to the current domestic manufacturers is less, the cost is higher, there is no available on business skills and service levels, followed by cold in subgroups matching liquid, by using less, time is short, ageing problems needs the test of time. Attachment: optical fiber welding skills to introduce what is fiber cut boot? A: fiber cut boot, namely a fixed way must cut fiber optic cable, such as device, primary effect is to complete the standard smoothness and the incision is smooth, in preparation for the next optical fiber welding optical fiber welding machine is what? Answer: optical fiber welding machine, the optical fiber on both ends of the cut is good, according to the standard parameter fusion connection, make the light in a first transmission signal is normally do what purpose? Answer: the two devices is normal is to do an entire toolbox placed first for local engineering used in optical fiber transmission signal, because the pick up of the fiber and access, must be involved in the seamless connection: what is the first of the fiber requirements? A: now have a special training part of the optical fiber welding personnel training, the first in the training, and education has nothing to do anything else, first used in informatization engineering personnel, usually in 20000 - a device 100000 primary factors of optical fiber splicing loss affects between optical fiber splicing loss is more, the elements of fiber can be divided into intrinsic factor and extrinsic factor. 1. Fiber intrinsic elements is refers to the fiber itself, the first four. ( 1) Optical fiber mode field diameter is inconsistent; ( 2) Two optical fiber core diameter mismatch; ( 3) Fiber core section not round; ( 4) Poor fiber core and cladding concentricity. Extrinsic factors can affect the fiber connection loss in skills. The influence of other factors. In personnel operating level, operation process, pan fiber technology level, welding machine, welding electrode cleaning of parameter Settings, and degree of cleaning work environment will affect the splicing loss value.
