How to use the fiber fast connector / cold connector

The wide application of optical fiber to the home (FTTH) has promoted the rise of optical fiber fast connector / cold connector. This product has the characteristics of small size, quick termination, and small loss and high stability, which is an essential optical fiber connection device for optical fiber system.

Optical fiber fast connector / cold connector

Optical fiber fast connector / cold connector is a very innovative field terminal connector, it contains internal factory pre-installed fiber, pre-research throw ceramic core and a mechanical connection mechanism, terminal when only to introduce optical fiber or indoor fiber inserted into the mechanical connection mechanism, without other tools, terminal process as long as 2 minutes, greatly save the installation time. The fiber fast connector / cold connector currently on the market can end single and multimode fibers with diameters of 250 μ m, 900 μ m, 2.0 mm and 3.0 mm. Optical fiber fast connector / cold connector can be directly applied to the corridor, household cable and other environments, without redundant protection, can basically reach the original line strength, reduce the wiring requirements, so the speed of FTTH optical fiber wiring is greatly improved, is an important guarantee for the realization of all-optical network.

Internal structure of fiber fast connector / cold connector

The core and end surfaces of the fiber fast connector / cold connector are pre-ground and pre-polished before leaving the factory. The mechanical connection mechanism is located at the end of the core to fix the inserted fiber. The mechanical connection mechanism is mainly composed of V-shaped slot and clamp elements. When the fiber needs to be inserted, open the V-shaped slot with a wedge clip to facilitate the smooth insertion of optical fiber. When the fiber is inserted into the V-shaped slot and fixed, remove the wedge clip from the V-shaped slot.

Operating principle of fiber fast connector / cold connector

Optical fiber fast connector / cold connector can be divided into two categories: preset fiber and non-preset fiber. The connection point of preset fiber fast connector / cold connector is inside the connector with preset matching fluid; the connection point of non-preset fiber fast connector / cold connector is on the connector surface without preset matching solution, and directly connects with the target fiber through the adapter. The working principle of non-preset fiber fast connector / cold connector is very simple and will not be described here.

Features and applications of fiber optic fast connector / cold connector

Main characteristics: good stability of the connection, small insertion loss, low use cost, installation speed is very fast and installation and maintenance is very simple.

Main applications: optical fiber communication application, optical fiber to the home (FTTH) application, cable TV application.

Use for of fiber optic fast connector / cold connector

Despite the simple use of the fiber fast connector / cold connector, the correct steps are followed and, in general, the fiber fast connector / cold connector is installed as follows:

Step 1: prepare optical fiber fast connector / cold connector, optical fiber wire cutters, optical fiber cutting knife, optical fiber cleaning tools, etc.;

Step 2: Put the connector tail cover on the cable;

Step 3: Remove the outer sheath of the optical fiber with the optical fiber stripping pliers, clean the optical fiber, and then cut the bare fiber with the optical fiber cutting knife. The length of the bare fiber is reserved according to the specific situation;

Step 4: Insert fiber into fiber fast connector / cold connector;

Step 5: Press the pressure cover, lock the optical fiber;

Step 6: Wear the tail cover on the fiber fast connector / cold connector.

Optical fiber fast connector / cold connector are highly susceptible to contamination and should be kept away from areas with more dust and pollutants.

The result of fiber cutting has an important impact on the performance of fiber fast connectors / cold connector, preferably using automatic fiber cutting knife for optimal cutting effect.

When inserting the fiber in the fiber fast connector / cold connector, it should be inserted slowly to prevent damage to the fiber, resulting in poor transmission performance of the fiber.

Do not remove the fiber fast connector / cold connector until it is installed.

It is important to choose excellent fiber refractive index matching solution, which can greatly extend the service life of fiber fast connector / cold connector.
