FTTH not only provides larger bandwidth, and strengthened the transparency of network to data form, speed, wavelength and agreement, relaxed the requirement to environment and power supply etc., simplified and safeguarded and installation, has the ability of transmitting simultaneously TDM, IP data and video broadcasting business, wherein the form of TDM and IP the data IEEE802.3 Ethernet transmits, be aided with the carrier-class network management system, be enough to guarantee transmission quality, can realize the professional transmission of video broadcasting by using the 3rd wavelength (being generally 1550nm).

ODN is based on the FTTH fiber cable network of PON equipment.Effect is for providing transmission line between OLT and the ONU.Divide from function, ODN can be divided into the feeder line optic cable subsystem from the local side to the user side, optical distribution cable subsystem, what four part of fibre-optic terminus subsystem of indoor wiring cable subsystem.

Summary of the invention

The purpose of this utility model is a kind of indoor armouring optoelectronic composite cable, has realized that photoelectricity transmission coexists to finish in the cable; Use rated voltage 450/750V and following BLV, can satisfy, (main line--the three-phase four-wire system) of the certain load requirement of transmitting electricity in the building the residential quarter in; Cable contains tight tube fiber, can satisfy good Optical Fiber Transmission and require (multimode fiber or G.652/G.657 optical fiber); The light transmission does not interfere with each other (optical fiber communication should be able to be born electric power transfer and be brought the load temperature rise) with electrical transmission; This cable also has good performance and resistance to bend(ing) energy, good environmental resistance, the indoor good fire resistance of laying.The utility model is applicable to the section of registering one's residence that is wired in the ODN system, but the electricity in the transmission equipment and light signal.

Technical scheme is as follows: indoor armouring optoelectronic composite cable comprises the optical fiber that wraps in the tight sleeve layer, wraps in copper conductor and oversheath in the insulating barrier, it is characterized in that: wrapping in outside the optical fiber 1 in the tight sleeve layer 2 is reinforcement layer 3, low smoke and zero halogen sheath 4 outside the reinforcement layer 3, a plurality of low smoke and zero halogen sheaths 4 are by low smoke and zero halogen sheath 5 parcels, low smoke and zero halogen sheath 5 outer wrapping waterstops 6 wrap the optical fiber of water blocking tape layer 6 and wrap in insulating barrier 9 interior copper conductors 8 and wrapped up by outer jacket 10 together.Reinforcement layer 3 is aramid fiber reinforcements.The waterstop 6 outer plastic-coated metal levels 7 that are surrounded by.Outer jacket 10 is PE outer jackets.

The utility model has the advantages that:

1, this optical cable is a kind of novel access way, and its light harvesting fibre, transmission of electricity copper cash are introduced apartment house more convenient access is provided for Fiber to the home in one.

2, the problems such as broadband access, equipment electricity consumption have been solved.

3, external diameter little, lightweight, take up room little (series of problems that generally could solve with many cables can replace with a composite fiber cable at this).

When 4, terminal is used, can select quick connector or optical fiber pigtail hot melt by item.

5, client's purchase cost is low, and operating expenses is low, and the networking expense is low.

6, have superior bending property and good anti-side pressure performance, easy construction, provide multiple transmission technology simultaneously.

7, the adaptability with equipment is high, and extensibility is strong, and that product uses is wide, huge broadband access can be provided, solve equipment electrical problem (avoiding repeating to put supply line) in the networking.

Embodiment

Comprise the optical fiber that wraps in the tight sleeve layer, wrap in copper conductor and oversheath in the insulating barrier, wrapping in outside the optical fiber 1 in the tight sleeve layer 2 is reinforcement layer 3, low smoke and zero halogen sheath 4 outside the reinforcement layer 3, a plurality of low smoke and zero halogen sheaths 4 are by low smoke and zero halogen sheath 5 parcels, low smoke and zero halogen sheath 5 outer wrapping waterstops 6 wrap the optical fiber of water blocking tape layer 6 and wrap in insulating barrier 9 interior copper conductors 8 and wrapped up by outer jacket 10 together.Reinforcement layer 3 is aramid fiber reinforcements.The waterstop 6 outer plastic-coated metal levels 7 that are surrounded by.Outer jacket 10 is PE outer jackets.

The utility model at first tightly overlaps protection with an optical fiber, uses aramid fiber as reinforcement again, surperficial sheath PVC, and copper line surface jacket insulation material, this element spiral is stranded to together, and the metal armouring sheath is made the finished product cable.Element adopts the matter annealed copper wire, can provide electric power energy in longer scope, high-quality optical fiber ensures the high-bandwidth signals transmission, solves the application places such as remote unattended equipment room, residential quarter machine room, mobile base station, user's access, directly access device is realized the photoelectric synchronous transmission.

Production process:

This product is selected sped structure production:

1, optical fiber tightly overlaps coating

For protection optical fiber is not subjected to external action directly to squeeze into the process of the suitable plastics tight buffer layer of one deck outside optical fiber coating, be called tight cover technique.

Production principle: the material that utilizes traction to provide constant speed that plastic extruding machine is extruded pulls into tubulose by mould, by inhaling vacuum plant tight cover material is combined on the optical fiber closely, and the external diameter of tight tube fiber is generally about 0.9mm.

2, single core cable

The structure of single fiber cable be outside a tight tube fiber around on aramid fiber to strengthen the mechanical strength of optical cable, then polyvinyl chloride (PVC) sheath stranding.

3, copper cash insulating barrier sheath

The insulating material isolation will be arranged between the insulated electric conductor.Otherwise this wire rod just can not use.Our employed main insulating material is PE (polyethylene).Utilize extruder to finish the copper line surface sheath.

4, stranding

With copper cash with single core cable naturally stranded to, reinforcement need not used in the centre, and is excessive for preventing yarn-binding tension, is adjusted to inertial states, purpose be element is closed as a whole.

5, oversheath

The restrictive coating of optical cable is used for protecting cable core, makes cable core avoid extraneous mechanism and environment bar

The impact of part, different jacket structures is applicable to different system of layings, the general built on stilts steel-tape armouring sheath that uses; Direct-burried uses the bonding sheath of plastic-aluminum; Indoor use then needs fire proofing.

We can select different sheath materials according to customer requirement.

6, oversheath

We can select different sheath materials according to customer requirement.
