PklzNet 20PCS LC-UPC Fiber Optical Loopback Duplex Plug Tester Single Mode G.657A2 Cable Adapter for SFP SFP28 Troubleshooting Testing
- Main Parameters 20PCS LC-UPC Singlemode G.657A2, Flame-Retardant Boxed loopback, suitable for 1310/1550nm Optical Signal Transmission. Operating Temperature: -20C to 75C, Storage Temperature: -40C to 75C
- Operating principleThe core of the optical fiber loopback device lies in establishing a "transmit-receive" closed-loop optical link. The signal is directly reflected back to the receiving end via the low-loss optical path inside the loopback device, enabling self-loop verification of optical signals without the need to construct an external test link. This ensures stable signal transmission, avoids attenuation interference, and significantly simplifies the testing process.
- Advantages and FeaturesThe product has a small size and short circuit, reducing the confusion of lines in the computer room, making the fiber optic connection logic clearer, facilitating quick identification of lines during later maintenance, and reducing the probability of misoperation caused by disorderly lin

Product descriptionFiber optic loopbacks achieve signal self loop verification by constructing a closed-loop optical link, without the need for external testing links, ensuring stable signal transmission. The product has a compact size and short wiring, reducing the confusion of lines in the computer room; Adopting A-grade zirconium ceramic core and sealed flame-retardant shell, it is durable for thousands of insertions and removals, isolating impurities and preventing attenuation. Widely applicable to the production of communication equipment such as optical modules and switches, it can quickly detect core indicators such as transmission power and reception sensitivity.
