Product Description
This SC Bare Fiber Adapter is a simple and efficient solution for connecting bare optical fiber to SC-based testing systems. In many field or laboratory situations, engineers need to test a bare fiber before making a permanent connection. Instead of installing a connector or performing fusion splicing, the fiber can be stripped, cleaned, cleaved, and inserted directly into the adapter for temporary measurement.
The blue SC connector side is suitable for SC/UPC applications and can be connected to standard SC adapters, SC patch cords, optical power meters, light sources, OTDR ports, and other compatible test devices. The black bare fiber end is designed to hold the stripped fiber in place, while the metal knob allows the operator to tighten the clamp and maintain a more stable test connection.
This product is especially useful in environments where fast testing and repeated operation are required, such as fiber optic installation, FTTH deployment, data center cabling, telecom maintenance, laboratory testing, and factory quality control.
Main Benefits
Fast temporary connection
The adapter allows bare fiber to be connected quickly after stripping and cleaving. It saves time compared with making a permanent connector and is especially useful for quick field checks.
No fusion splicing required
Engineers can connect bare fiber directly to SC test interfaces without using a fusion splicer, mechanical splice, or connector polishing process.
Stable clamping structure
The bare fiber end includes a mechanical clamp and metal tightening knob, helping reduce fiber movement during measurement.
Compatible with SC testing systems
The SC/UPC connector end works with common SC adapters, patch cords, optical power meters, light sources, OTDRs, and related fiber optic testing equipment.
Portable and easy to use
The adapter is small, lightweight, and does not require power. It can be easily carried in a field tool kit for installation and maintenance work.
Suitable for batch use
The product images show clear blister tray packaging with 10 pcs per tray, making it convenient for storage, transportation, and bulk supply.

How to Use
- Strip the coating from the optical fiber to expose the bare fiber.
- Clean the bare fiber carefully with lint-free wipes and alcohol.
- Cleave the fiber end face with a fiber cleaver.
- Loosen the metal knob on the bare fiber adapter.
- Insert the bare fiber gently into the clamping end.
- Tighten the metal knob to hold the fiber in place.
- Connect the SC/UPC end to the test device, SC adapter, or SC patch cord.
- Perform the required optical test.
- After testing, loosen the knob, remove the fiber, and cover the SC end with the dust cap.
Usage Notes
- The cleave quality of the bare fiber directly affects insertion loss and test stability.
- Always clean the bare fiber before inserting it into the adapter.
- Do not bend, twist, or force the bare fiber during insertion.
- This product is intended for temporary test connection, not permanent network deployment.
- Keep the dust cap on when the adapter is not in use.
- If test readings are unstable, check the fiber cleave, insertion depth, clamp tightness, and connector cleanliness.
