Description
Technical field
The utility model relates to a kind of optical cable, belongs to communication device field, is specifically related to a kind of optical cable with connector.
Background technology
Hard-pressed bale indoor horizontal wiring optical cable is very important ingredient in room light communication system, and it is of many uses, external diameter is little, lightweight, and has certain flame-retarding characteristic, and mechanical property requirements is moderate and with low cost.Therefore be usually used in interconnecting between each communication facilities in the interconnection in communication facilities between each light delivery module, communications equipment room, and the laying or the laying of vertical wirings in non-super high constructure of multicore horizontal wiring in light comprehensive wiring.
The structure of this optical cable is very simple, in cable core transmission medium twisted by spiral or left and right strand (also known as SZ strand) many tightly packaged fibers form, the skin of tightly packaged fiber aramid yarn (Nomex) layer that be arranged in parallel ensures the intensity of optical cable, the coated flame-retardant polyolefin sheathed or flame-proof polyvinyl chloride sheath in outside.Wherein between sheath and aramid fiber layer, and must not adhesion be had between tightly packaged fiber and aramid fiber layer, otherwise the change that will optical cable caused to decay.Due to not containing metal or metalloid core reinforcement in the cable core of this structure, therefore have in actual cloth cable process and strict lay construction regulations.But in actual optical cable work progress, when particularly while of many indoor horizontal wiring optical cables, cloth is placed in same communication pipe or vertical shaft, the increase heavy due to cable and the irregularity of profile cause the friction of tube wall, required tractive force in construction all will be caused to increase, and the phenomenon that there will be on a certain that main tractive force mainly acts in many indoor horizontal wiring optical cables, certain root cable jacket is caused to be elongated and to cause damage to the tightly packaged fiber of optical cable like this, it shows as tightly packaged fiber cable core and is shorter than sheath, and additional attenuation increases to make tightly packaged fiber occur, step and even disconnected fine event occur.This to be pulled long phenomenon by sheath be random, or even in construction, all optical cables have sheath in various degree to elongate phenomenon.
In special sheath tractive force excessive tensile in the test of tightly packaged fiber impact in cable, within the set time, 20 meters long one section is got from a dish optical cable, and the power being respectively applied above 50 kilograms at two ends stretches, there is the deformation set at least occurring 0.3% in sheath, tightly packaged fiber has obvious attenuation change, step or attenuate linear bending simultaneously.Dissect tested optical cable, find that in cable, the phenomenons such as minor radius is bending appear in tight tube fiber.
The mechanical property design of conventional chambers horizontal wiring optical cable need be followed maximum stress that optical cable may use and design, its prolonged application power should be not less than the weight of 200 meters of these structure cables, and short-term tension force is 3 times of this long-term tension or is not less than 600N (getting the maximal value in these two values).This tensile force will determine the consumption of aramid fiber layer in optical cable, and have influence on optical cable total by stress-strain.When tension force of constructing acts on optical cable, first acting force acts on sheath, then relies on sheath and the friction of aramid yarn interlayer and the friction between aramid fiber layer and tightly packaged fiber to be transmitted on all optical cable components.The transmission of this power non-fully is uniform, cause sheath stressed more obvious thus, and each tightly packaged fiber is stressed also uneven, this uneven meeting causes above cable jacket to be elongated or the phenomenon such as additional attenuation, step appears in indivedual tightly packaged fiber.When tractive force short-term of particularly constructing exceedes unit cable 200 meters of optical cable cables weights, cable jacket is likely impaired by excessively elongating.And once after fiber cable laying, it will be very difficult for again changing optical cable.Therefore need likely to be applied to the optical cable that interior conduit, vertical shaft and groove lay to this better drawing tension of resistance to construction is provided, and need the ability of the tension effect strengthening cable jacket especially.
