Description
Technical field
This utility model relates to optical cable art, refers in particular to a kind of high fire-retardance fire-resistant net mask optical cable.
Background technology
Along with the arrival of information age, the conveying capacity of information is explosive growth, and as Large Copacity, the effective means of long range propagation, optical fiber cable has obtained extensive and substantial amounts of application, and the application of optical cable is the most gradually developed to Metropolitan Area Network (MAN), access network direction by long distance line.
Current optical cable generally exists that flame-retardant is bad, and shield effectiveness is the best, causes product serviceability to decline, therefore, it is necessary to improve current optical cable.
Utility model content
In view of this, this utility model is for the disappearance of prior art existence, and its main purpose is to provide a kind of high fire-retardance fire-resistant net mask optical cable, and it can effectively solve existing optical cable and there is the problem that flame-retardant fire-resistant is bad, shield effectiveness is the best.
For achieving the above object, this utility model uses such as purgation technical scheme:
A kind of high fire-retardance fire-resistant net mask optical cable, includes the outer fire-retardant flame retardant coating of a center reinforcement, multiple fiber unit, a water blocking layer, an armor, an oversheath, an external shielding layer and；The lateral surface of this center reinforcement is arranged with multiple arc groove, the plurality of fiber unit is partly embedded in the arc groove of correspondence respectively, each fiber unit includes protecting pipe, internal shield, interior fire-retardant flame retardant coating and multifiber, this multifiber is arranged in protecting pipe, fine cream it is filled with in protecting pipe, this internal shield is coated on outside protecting pipe, this interior fire-retardant flame retardant coating is coated on internal shield, this water blocking layer envelopes center reinforcement and multiple fiber unit, this armor is coated on outside water blocking layer, this oversheath is coated on outside armor, this external shielding layer is coated on oversheath, this outer fire-retardant flame retardant coating is coated on external shielding layer.
As a kind of preferred version, described center reinforcement is FRP metalloid core reinforcement.
As a kind of preferred version, the inner side of described protecting pipe is provided with dubbin layer of paste.
As a kind of preferred version, described fiber unit is six, and each fiber unit is respectively provided with seven optical fiber.
This utility model compared with prior art has clear advantage and beneficial effect, specifically, as shown from the above technical solution:
By being equipped with inside and outside screen layer and inside and outside flame-retardant layer, achieve good flame-retardant performance, and shield effectiveness is good, ensure that the quality that signal transmits, and this product has good fire resistance characteristic, fiber unit realizes well location, and product serviceability is good, is widely used in network and connects.
For more clearly illustrating architectural feature of the present utility model and effect, with specific embodiment, this utility model is described in detail below in conjunction with the accompanying drawings.
