光纖識別儀/Optical fiber Identifier:

廣泛用于光纜施工及維護。利用宏彎技術對線路做無損測試，可以測量信號方向及功率，避免誤操作導致線路中斷。

Widely used in optical cable construction and maintenance. The use of macro bending technology To do non-destructive

testing. can measure the signal direction and power, to avoid misoperation resulting in interrupted lines.

宏彎測量，宏彎是利用光纖彎曲時泄漏出微弱的光信號,通過判斷泄漏的方向和強度來檢測光

信號的方向和強度。不損傷光纖,不中斷通信,并可以直接檢測0.25mm裸光纖, 0.9mm緊套管光

纖和2.5mm跳線。

Macro bending measurement, macro bends are the use of fiber-optic bending leak out when the weak optical signal, optical signal to detect the direction and intensity. Does not damage optical fiber, without interrupting communications, and direct detection of 25mm bare fiber, 0.9mm and 2.5mm fiber casing tight jumper.

音頻識別，光纖識別儀可以檢測光信號中加載的固定音頻信號,270Hz,1KHz和2KHz，用以識別

特定光纖,可以快速的找到需要的光纖。

Tone identification, Optical Fiber Identifier can detect optical signals in the tone signal

a fixed load, 270Hz, 1KHz and 2KHz, to identify a specific optical fiber, can quickly find

the necessary fiber.

低電量監測功能，光電話自帶電量監測，當電池電量不足時會發出指示，來提醒用戶更換電

池，以免使用中斷。

Low battery monitoring function, when battery power is insufficient to issue instructions

to remind users to change batteries.

使用康寧SM標準光纖，250um裸光纖取紅、黃、橙、藍、綠色及棕色涂敷層裸光纖，參數取各種顏色涂敷層的平均值，900um和3mm取白色和黃色標準

跳線。如果裸光纖涂敷層為黑色，光衰減很大或不能測量。

AFI420-S輸出功率>1mW線路衰減小時可在5KM處看見紅色激光,AFI420-L輸出功率>10mW線路衰減小時可在10KM處看見紅色激光。
