SC Fiber Fast Connector

SC fiber fast connector is a connection device for transmitting optical signals. The connector has a built-in V-groove structure and a pre-embedded fiber segment. When installing, you only need to insert and lock the fiber to complete the connection, which greatly improves the construction efficiency.

Low Loss
The signal transmission loss of the SC fiber fast connector is below 0.2dB, which is 30-40% lower than the 0.3-0.5dB loss of ordinary adapters. This is because the adapter uses a precision ceramic sleeve. Its inner diameter tolerance is controlled within ±0.001mm, which is much better than the industry standard ±0.003mm requirement. This enables the adapter to achieve precise docking between fiber cores and minimize light energy loss.

High Return Loss
High return loss means that the reflection interference is small, which can effectively prevent the reflected light from interfering with the transmitting end laser, thereby reducing the bit error rate (BER). The return loss of the SC fiber fast connector is as high as ≥45dB (single mode) or ≥30dB (multimode), which is a performance indicator far exceeding many other types of connectors. For example, ordinary FC connectors can usually only achieve a return loss of about 40dB.

Quick Installation
SC fiber fast connector adopts snap-on design. The plug shell is a rectangular plastic shell. When the adapter is inserted, the internal elastic snap (shrapnel) will automatically lock into the socket without rotation. When unplugging, just press the snap part lightly and pull out the plug. Compared with the traditional FC thread tightening structure, our connector installation time is shortened from an average of 15 minutes to only 6 minutes.

What is the difference between embedded fiber optic quick connectors and through connectors?

The technology used for fiber optic quick connectors is divided into two categories: pre embedded fiber optic and non pre embedded (straight through) fast connector fiber optic.

The main difference lies in the connection point and connection method:

1. Connection point settings

The connection point of the embedded optical fiber is set inside the connector, and the embedded optical fiber has a preset matching liquid;

The connection point of non embedded (straight through) optical fiber is on the surface of the connector, without pre installed matching liquid, and is directly connected to the target optical fiber through the adapter.

2. Connection method

The fiber optic quick connect connector is used to thread and fix the fiber into the pin, and after polishing the surface of the pin, achieve alignment in the coupling tube. The outer components of the pin are made of metal or non-metallic materials. The docking end of the pin must be ground, and the other end is usually supported by a bending limiting component to release stress on the fiber or fiber optic cable. The coupling tube is generally made of a two half composite, fastened cylindrical component made of materials such as ceramics or bronze, and is often equipped with metal or plastic flanges to facilitate the installation and fixation of connectors. In order to align the optical fiber as accurately as possible, there is a high requirement for the machining accuracy of the pins and coupling tubes.

There are no embedded optical fibers or matching paste inside the straight through optical fiber quick connector device. After the optical fiber is installed and clamped, a magnifying glass can be used to inspect the end face of the optical fiber to avoid excessive fiber connection loss. Axial positioning mechanism, during the clamping process, the optical fiber will not move forward axially.

How to install and use SC Fiber Fast Connector?

1. Remove the connector tail cover and thread the cable through it;

2. Use fiber optic cable stripping pliers to peel off the outer skin of the cable, with a length of approximately 5CM;

3. Close the Miller pliers to the edge of the fixture and cut off the exposed coating layer to expose the optical fiber;

4. Wipe and clean the bare optical fiber with a dust-proof cloth;

5. Cut the optical fiber with a fixture;

6. Align the fiber optic cable with the main hole slot and insert it. When the fiber optic cable initially shows a bent state, press the crimping cover down;

7. Twist the tail cover of the string cable back onto the connector body and fasten the outer shell.
