OPLC shows significant advantages, power fiber to the home, gets rid of the chronic illness of “last one hundred meters "
The power line has long been a household word, as the most extensive coverage of network resources. Fiber-optic cable carrying electricity transmission lines, while laying of power transmission cable, completing fiber optic cable laying Synchronously, making the cost greatly reduced, also saving the pipeline resources within the building. Plagued by communications operators for many years, "the last one hundred meters of access illnesses, may be solved with a large number of applications of OPLC cable.
Introduction
1.Executive Standard: Q/GDW 521-2010.
2.Application: The product replaces electric power communication currently, and thus realizing PFTTH, which provides a network of high bandwidth and reliability, and realizing smart grid end-user accesses and a large quantity of electricity information exchanges. It solves “the last three hundred meters” problem of information super highway efficiently, and it can also serve “Tri-networks Integration” simultaneously when meeting the demand of smart grid.
3.Product characteristics:
(1)The product has the characteristics of both power cable and optical cable, which can transmit electric power and high-speed communication information to users, the product also has the characteristics of low attenuation, low noise and no teratogenicity, so as to meet the demand of smart grid and “Tri-networks Integration”.
(2)If the optical unit of the product is filling type (i.e. the structural code of the type is CTG or XTG), it cannot be applied to occasions of vertical laying and of large fall.
(3)The optical unit of the product meets the requirements of GB/T9771-2008 and the multicore cable meets relevant requirements of GB/T12706.1-2008.
(4)For the product of flame retardant, its flame retardant property meets the requirements of GB/T19666-2005.
(5)For the product of low smoke & non-halogen, it meets the relevant requirements of GB/T19666-2005.
(6)The laying temperature of cables shall be no less than 0℃.
(7)The minimum bending radius of the product shall be no less than 15 times of OPLC’s outer diameter when in static state, and the minimum bending radius of the product shall be no less than 20 times of outer diameter when in movable state.
(8)The product shall not be stored in the open air, and cable drum is not allowed to be put flatwise. It is forbidden to throw cable drum from high spot during the transportation, and any mechanical damage to lifting parts or transport packages is not allowed, and a number of drums lifted simultaneously is also not allowed. The cable drums shall be put steadily and be fixed in a proper way to avoid collision and overturn while on the vehicles, such as trucks, ships and etc.
4.Representation method of the product.
(1)Series code: OPLC
(2)Special code of the cable:
W – non-halogen, D –low smoke, Z- flame retardant, ZA –flame retardance of Class A, ZB –flame retardance of Class B, ZC- flame retardance of Class C.
Cable structure code: consist of conductor, insulation, inner separation layer (inner liner, separate bedding), armor layer, outer sheath and the same as common power cables.
(3)Optical fiber description: including optical type and the number of optical cores. The number of optical cores is expressed in number, optical type involves single mode fiber and multi-mode fiber as to transmitting mode. The product commonly means single mode fiber, and IEC divides the single mode fiber into B1.1, B1.3, B4 and B6; hereby optical fiber is represented like this.
