What does an optical fiber cold connector mean, its usage and function

Cold splicing is a kind of optical fiber fusion splicing (splicing), the purpose of which is to connect the tail of the optical fiber to the pigtail, and use the plug on the pigtail to easily connect the optical modem equipment.

For example, in the current FTTH home, many of them use cold splices and pigtail connectors together (in fact, the optical fibers in the optical cable and the optical fibers in the pigtails are crimped together in a physical way), and the end faces should be aligned and close as possible to ensure the normal transmission of optical signals and the minimum loss of optical signals.

There is also a kind of hot melting, which is to use a fusion splicer to hot-weld the end faces of two optical fibers together after instantaneous discharge.

Cold splicing is a type of optical fiber connection, which uses a fiber optic adapter commonly known as a union joint. In the early unions, there was a fiber optic cable matching solution to prepare the end face of the optical fiber and insert it into the union to connect the interrupted optical fiber, or the optical fiber was prepared into a pigtail connector and connected with a flange head. Most of today's unions do not have matching fluids.

Just insert the prepared endface of the fiber into the adapter.

If it is made of pigtail joints, you need an instrument that can enlarge the end face of the fiber to see if the joints you have prepared meet the requirements.

There are two ways to connect fibers:

One is the cold connection of the cold connector, which is connected by physical method, and the loss is relatively large.

The second is to use a fusion splicer to weld and connect the core of the optical fiber by heating, which has a small loss.

1. Tools required: Miller pliers, mainly used to strip optical fiber coatings; Stripper, stripping the outer skin of the optical fiber; cold splicers for connecting optical fibers; Cut-to-length stripper and cutting knife, combined with the use of erection, determine the length, and cut the optical fiber.

2. Strip off the outer skin of the optical fiber;

3. Put the optical fiber into the fixed-length stripper, and pay attention to the reserved optical fiber length;

4. Peel off the optical fiber coating with Miller liquid chain pliers;

5. Use an optical fiber cutting knife to cut optical fibers;

6. Insert the cut optical fiber into the cold connector and pay attention to locking;

7. After the production is completed, if there is a red light pen, it can be tested by the red light.

Hello Kiss, happy to answer your questions. Optical fiber cold and smile smart connector devices include: fiber optic cable, connector call, cold head, cold shoe, cold scar, coupler, cold press, etc.

The optical fiber connector is a device that connects the optical cable and the connector together, and its function is to make the rising finger connection between the optical cable and the connector more solid and durable. A cold head is a connector that connects a fiber optic connector to a PCB board and is designed to withstand temperature changes, vibration resistance, durability, and overvoltage protection, among other things. The cold shoe uses a special material that reduces variable temperature and humidity resistance, thereby protecting and improving the electrical properties of multiple fiber splices.

A coupler is a kind of beamsplitter that couples the input and output signals of two optical fibers together, such as thin film couplers, multimode couplers, wave link couplers, wave splitters, etc. The cold press is used for electrostatic contact and tensile crimping of the joint, sealing and waterproofing, ensuring the firmness and reliability of the optical fiber connection and joint.

Fiber optic cold junction devices typically include the following components:1Fiber Optic Connectors:

It is used to connect optical fibers, and usually adopts standard interfaces such as FC, SC, ST, etc. 2.Fiber Optic Adapter:

It is used to connect different types of fiber optic connectors to realize the connection between optical fibers. 3.Fiber Optic Attenuator:

It is used to adjust the strength of optical signals and is typically used to test and debug fiber optic networks. 4.Light Wheel Fiber Splitter:

It is used to split optical signals into multiple channels, and is usually used for fiber optic communication and transmission. 5.Fiber Optic Coupler:

It is used to merge multiple optical signals into a single signal, and is usually used for fiber optic communication and transmission. 6.Fiber Optic Amplifier:

It is used to amplify Yetan optical signals, and is usually used for optical fiber communication and transmission. 7.FBG:

It is used to filter optical signals and is typically used for fiber optic communication and transmission. 8.Fiber Optic Switches:

A switch used to control optical signals, typically used for fiber optic communication and transmission. These components can be combined as needed to form different types of fiber optic cold splices to meet different application needs.

1. Advantages:

It is used for optical fiber docking optical fiber or optical fiber docking pigtail, which is equivalent to making a joint, (optical fiber docking pigtail refers to the core docking of the optical fiber and pigtail rather than the pigtail head mentioned in the former), and the thing used for this kind of cold splicing is called optical fiber cold splicer.

The optical fiber cold splicer is used when two pigtails are docked, and its main internal component is a precision V-shaped slot, and the cold splicer is used to realize the docking of the two pigtails after the two pigtails are dialed.

2. Disadvantages: "At present, there are fewer domestic manufacturers who can directly produce cold splices, the cost is high, and there is no room for choice in business and technical services, followed by the use of matching liquid in cold splices, because of the use of less, short time, aging problems need time test.
