Designed for professionals, it enables live fiber traffic detection without disconnection, includes LED lighting for dark environments, and supports efficient troubleshooting with tone detection up to 6,000ft. Ideal for fiber technicians seeking reliable, portable, and cost-effective network testing. ## Description ORIENTEK TFI-40 Optical Fiber Identifier All-in-one Chuck Live with 10mw VFL 800nm-1700nm Fiber Detector Traffic Identifier OFI: desertcart.com: Industrial & Scientific Review: Fiber identifier - Work perfect for troubleshooting and to see if you got light levels before you cut it or before the splicer you don’t need a pick tail to check the light for troubleshooting came with laser on the bottle. Also, A light if you work in the dark. Review: Not a precision db meter, but it does what I need it to do. - I’m a fiber technician and I got this tool for two reasons: I wanted to be able to see if a fiber has traffic without unplugging it, and I wanted something that could detect 2khz tone. This product does both. I paired it with the Orientek T15M light source, which I use to generate the 2khz tone. This device always picks up the tone — the furthest distance I’ve tested so far is around 6,000ft. So I’m satisfied with that function. I compared the wand’s db readings to the db readings from my Viavi Optimeter, and the wand tends to read over or under by quite a bit… but that’s a $5,000 meter and this is a $70 wand. Bottom line: if there’s traffic on the fiber, it always detects traffic. If there’s no traffic, it always reads “Lo.” Other reviews have said that they have issues with the wand reading no traffic when the fiber does have traffic, but I have not encountered this issue in the field after 1 month of use. I would say I 100% trust this device as a live fiber identifier. Only possible quirk is that it often detects 270hz tone on fibers that do not have a tone generator hooked up to them. I cannot tell if this is a defect in the device, or if there is something on my employer’s fiber network that reads as 270hz. So, the only issue I’ve had to work around is double checking that when the wand beeps from the tone, it’s reading the 2khz from my light source and not the 270hz from the splitter. Conclusion: it does what it’s supposed to do very well for the price. If you want pinpoint precision, then you’ll have to look in the $600 - $2,000 price range for an EXFO or Jonard wand. But if you already have a good db meter and want something under $100 for detecting traffic and tone, this is your best option. ## Features - Chucks: Multi in one chucks; Easy test directly,convenient and efficient; Suitable for 0.25; 0.9; 2.0 and 3.0mm - Design: Small and practical; No need to replace the chucks - Be equipped with LED light; More convenient to work in the dark - Friendship: Approximate core power reading; Battery low indication - Detector Type: 1mm InGaAs 2 pcs; Testing sensitivity -40dBm to 10 dBm ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07W92C319 | | Best Sellers Rank | #90,470 in Industrial & Scientific ( See Top 100 in Industrial & Scientific ) #171 in Network & Cable Testers | | Brand Name | ORIENTEK | | Customer Reviews | 4.4 4.4 out of 5 stars (106) | | Item Weight | 235 Grams | | Manufacturer | Nanjing Orientek Optical Communication Limited | | Model | TFI-40-BS-R | | Output Type | Analog | | Part Number | TFI-40-BS-R | | Sensing Distance | 0.25 Millimeters | | Smart Home Compatibility | Not Smart Home Compatible | | Specific Uses For Product | Indoor, Fiber Optic Network Testing, Identification | | Style Name | Modern | | Unit Count | 1.0 Count | | Upper Temperature Rating | 60 Degrees Celsius | ## Product Details - **Brand:** ORIENTEK - **Item Weight:** 235 Grams - **Output Type:** Analog - **Sensing Distance:** 0.25 Millimeters - **Style:** Modern ## Images ![TFI-40 Optical Fiber Identifier All-in-one Chuck Live with 10mw VFL 800nm-1700nm Fiber Detector Traffic Identifier OFI - Image 1](https://m.media-amazon.com/images/I/61vfDZUxidL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Fiber identifier *by A***L on March 4, 2026* Work perfect for troubleshooting and to see if you got light levels before you cut it or before the splicer you don’t need a pick tail to check the light for troubleshooting came with laser on the bottle.

It came quickly and worked as expected. Quality is also a expected. Even had a built in flash light along with the red light vault locator. ## Frequently Bought Together - ORIENTEK TFI-40 Optical Fiber Identifier All-in-one Chuck Live with 10mw VFL 800nm-1700nm Fiber Detector Traffic Identifier OFI - D YEDEMC Fiber Optic Cable Tester - Portable Optical Fiber Power Meter with Universal FC/SC/ST Interface and Built-in 2Mw Visual Fault Locator (OPM-VFL-1) - Jonard JIC-186 Kevlar Ergonomic Fiber Optic Cutter, 6" Length --- ## 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.hr/products/164072770-tfi-40-optical-fiber-identifier-all-in-one-chuck-live](https://www.desertcart.hr/products/164072770-tfi-40-optical-fiber-identifier-all-in-one-chuck-live) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-05-24*
