After some back and forth with the seller I got the missing parts (from China). It somewhat accurately reports cable lengths and reflected events, but it's extremely inconsistant. I can run the same test multiple times and get different results. I do find my self leaning it after every single use to keep it accurate. I bought a launch reel to hopefully eliminate some of the issues, but it didn't help much. There are some features that are greyed out that would be helpful (Pre/post launch length) being one of them. The copper tdr works very well and has actually helped with several projects. The power meter and VFL work well. The OTDR just isn't that reliable. ## Frequently Bought Together - Rsrteng OTDR Fiber Optical Tester 1310/1550nm 28/26dB 5" Touch Screen SM Fiber Tester Event Map RJ45 8GB TF Card PC-Sides Analysis Software Connector with UPC/SC FC LC ST - Visual Fault Locator Fiber Adapter, Fiber Optic Connector, 1pcs Single Mode 9/125um FC Male to LC Female Hybrid Optical Fiber Convertor Adapter Compatible with Optical Power Meter Visual Fault Locator --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.sn/products/508998201-rsrteng-otdr-fiber-optical-tester-1310-1550nm-28-26db-5](https://www.desertcart.sn/products/508998201-rsrteng-otdr-fiber-optical-tester-1310-1550nm-28-26db-5) --- *Product available on Desertcart Senegal* *Store origin: SN* *Last updated: 2026-09-10*
