What's the difference between optical cable and network cable? How to reserve optical fiber network cable for decoration? How to install the reserved optical fiber for decoration

Optical cable and network cable are all materials used in the weak current part of home improvement. Although they are all weak current wires, they are still very different. So what is the main difference between optical cable and network cable? The next article talks about the difference between optical cable and network cable, and at the same time talks about how to reserve optical cable for decoration and how to install optical fiber reserved for decoration. For the reference of decoration friends.

First, the difference between optical cable and network cable

Optical fiber cable and network cable are used as wires of two different circuits. The difference between optical cable and network cable is mainly reflected in the following aspects.

1, with different properties.

Optical fiber and network cable are different in nature, but different in essence. Optical fiber is an abstract concept and a dynamic information transmission rate. Network cable is the medium and carrier of information transmission.

2. Different roles

The function of optical fiber is to accelerate the transmission of different network information; Network cable is used to connect devices to improve the efficiency of network information transmission between devices.

3. Different ways of existence

They used to exist in different ways. Optical fiber exists in a virtual way, without physical objects. A network cable is a real cable with concrete objects.

4. Different application scenarios

Optical fiber is mainly used for broadband communication, which can provide users with interactive multimedia information of video, graphics, communication and data. For example: work conference video, online interactive games, remote video surveillance, etc.

Network cable is used to connect equipment, mainly for engineering wiring, network connection and connection of equipment port system. For example: switches, hubs, firewalls and other devices.

5. Different transmission rates

The transmission frequency of the best network cable category 7 can reach at least 500MHz, which is more than twice that of category 6 cable and super category 6 cable, and the transmission rate can reach 10Gbps. Optical fiber is the fastest transmission medium at present, which can reach 40G- 100G.

6. Different transmission distances

The theoretical transmission distance of network cable is only within 100 meter; Optical fiber transmission distance: 100base-fx single-mode module uses single-mode optical fiber transmission 10-20km, 100base-fx multimode module uses multimode optical fiber transmission for 2km, and when single-mode optical fiber is used, the maximum transmission distance is 3km.

Second, how to reserve optical fiber network cable for decoration

When the decoration lamp is installed, it is necessary to reserve a position before the decoration, so how to reserve a position for the decoration optical fiber network cable?

1, wired Internet access

In the study, master bedroom, etc. , use a desktop or laptop to surf the Internet. Its advantages are stability, high speed and no interference.

2. Wireless Internet access

At home, you can surf the Internet wirelessly with your laptop, PAD and smart phone anytime and anywhere. The advantage is that it is not limited by the network cable.

Step 3 surf the internet on TV

Watch iTV broadband interactive TV with iTV set-top box and cable broadband Advantages are over 100 sets of channels, 72 hours of viewing and 30,000 hours of massive on-demand.

4. Fixed telephone

Install fixed telephones in the living room, bedside and bathroom.

5. Others

Install cameras for home security monitoring.

6. Precautions for reserving optical fiber

(1) Home optical fiber is the entrance and exit of home Internet access. Fiber cloth will be placed in the information box indoors or at home, and a thin white or black leather line of about 50 cm will be reserved.

(2) The internal material of optical fiber is glass fiber, which cannot be excessively bent or broken. Please protect the optical fiber in the installation method, and don't cut it short or break it, so as not to bring trouble to the later installation.

(3) If the optical fiber does not enter the house in advance, please arrange the decoration personnel to embed concealed pipes with an outer diameter of not less than 20mm from the home information box to the outdoor or corridor weak box, and reserve traction wires in the pipes to facilitate fttp plugging and unplugging.

Third, how to install the reserved optical fiber for decoration?

How to install the reserved optical fiber for decoration? General home decoration should reserve optical fiber network. If the optical fiber doesn't enter the house in advance, the installer can embed a concealed pipe with an outer diameter of not less than 20MM from the family information box to the outdoor or corridor weak box, and reserve a traction wire in the museum, which can facilitate the plugging and unplugging of fttp. The home information box should be installed with a 220-volt power socket and electrified.

1. If the optical fiber does not enter the room in advance, please arrange the decoration personnel to embed the concealed pipe with an outer diameter of not less than 20mm from the home information box to the outdoor or corridor weak box, and reserve traction wires (such as iron wires) in the pipe to facilitate the optical fiber to enter the room.

2. Family information box is the gathering center of network cable, telephone cable and TV cable, which is generally embedded in the wall that enters the door. It is mainly used for storing "light cat" (optical fiber internet access equipment with WIFI wireless function), power sockets, telephone and TV wiring modules, and connecting weak current concealed pipes such as optical fiber, telephone line, network line and TV line. A 220-volt power socket should be installed in the box and electrified.

3. The box body of the household information box should not be too small, and the recommended size is not less than: the overall size is 330mm (height) ×480mm (width) × 135mm (depth); The size of the bottom box is 300mm (height) ×450mm (width )×120mm (depth), and there should be natural ventilation holes.

The above is about the difference between optical cable and network cable, how to reserve optical cable in decoration and how to install reserved optical fiber in decoration. I hope it will help everyone! Want to know more about the network cable, recommended reading: How to lengthen the reserved network cable if it is too short?
