I bought this because it was supposed to remove noise. I've been using it for about two years. This is a high-performance modular cable (TEL-FST-02N2) made by Sanwa Supply. ✅ Product Features * Length: 0.2m (20cm) * The high-density ferrite core and shielded twisted-pair structure stabilize communication in environments susceptible to noise, such as ADSL and ISDN. * Ideal for connecting telephone lines to modems, or modems to splitters, etc. * At 0.2m, it's short, making it very convenient for tidying up the wiring around your devices. ✅ Product Condition I am selling this to organize my equipment. I used it for a short period and then stored it in a dark place. There are no noticeable scratches or stains, and I think the condition is good, but please understand that this is a used item before purchasing. ✅ Other * Immediate purchase without comments is welcome. * If you have any questions, feel free to comment. Thank you. 【Hashtags】 #SanwaSupply #SanwaSupply #ModularCable #TelephoneLine #FerriteCore #NoiseReduction #ADSL #ISDN #PCPeripherals #WiringOrganization
