## Overview

The ORIENTEK TFI-40 is a compact, all-in-one optical fiber identifier featuring multi-size chucks (0.25-3.0mm), a sensitive InGaAs detector (-40dBm to 10dBm), and a built-in 10mW visual fault locator (800-1700nm). 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

Product description TFI-40 Fiber Identifier Upgraded high accuracy fiber identifier TFI-40 integrates VFL and LED lighting function,It is one of the necessary tools for fiber maintenance.Fiber identifier can detect any position of the single mode and multi mode fiber. With the fiber identifier to identify the fiber on the line, you can identify the fiber power and 3 kinds of signal frequencies, and there will be a buzzer sound when identifying the frequency.Display the signal direction via left and right direction light and to make prompt judgment.VFL adopt 2.5mm universal connector and output power is up to 10mW,It can detect fiber break or bending problems within 10km,and it supports pulse and continuous wavelength operation.And it equipped with LED light,convenient for you to work in the dark. Products characters and functions： ●Suitable for 0.25/0.9/2.0/3.0mm fifibers ● Test sensitivity: -40dBm to 10 dBm. ● Confifigure VFL function, 2.5mm universal ● Test distance up to 10km, high stability ● Be equipped with LED light,more con-venient to check the fifibers in the dark ● LED backlight display, suitable for variousenvironments without auxiliary lighting. ● Strong light source, strong penetrating power ● Easy to carry, no need to replace the chucks. Specification Type： TFI-40 Identified Wavelength Range: 800nm to 1700nm Identified Signal Type: CW,270 Hz ± 5%,1 kHz ± 5%,2 kHz ± 5% Detector Type: φ1mm InGaAs 2 pcs Adapter Type: Universal Holder for φ0.25(Bare Fiber),φ0.9,φ2.0,φ3.0 Cable Signal Direction: Left & Right LED Optical Power Reading: -40 dBm to 10 dBm Signal Frequency: 270Hz,1kHz,2kHz Power Supply: AA*2 Operating Temperature: -10℃ to 60℃ Storage Temperature: -25℃ to 70℃ PRODUCT SPECIFICATION

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.
