Part of EXFO's 600 handheld series, the FLS-600 offers laser and LED models across a range of wavelength options to match any fibre type and test requirement. The FLS-600-234BL variant provides three singlemode laser wavelengths — 1310 nm, 1550 nm, and 1625 nm — on a single port, enabling comprehensive testing of singlemode networks including passive optical networks (PONs) at the wavelengths recommended by ITU-T G.983.3.\u003c\/p\u003e\n\u003cp style=\"box-sizing: border-box; border-style: solid; border-width: 0px; border-color: rgb(217, 217, 217); -webkit-font-smoothing: antialiased; --sp-tw-border-spacing-x: 0; --sp-tw-border-spacing-y: 0; --sp-tw-translate-x: 0; --sp-tw-translate-y: 0; --sp-tw-rotate: 0; --sp-tw-skew-x: 0; --sp-tw-skew-y: 0; --sp-tw-scale-x: 1; --sp-tw-scale-y: 1; --sp-tw-pan-x: ; --sp-tw-pan-y: ; --sp-tw-pinch-zoom: ; --sp-tw-scroll-snap-strictness: proximity; --sp-tw-gradient-from-position: ; --sp-tw-gradient-via-position: ; --sp-tw-gradient-to-position: ; --sp-tw-ordinal: ; --sp-tw-slashed-zero: ; --sp-tw-numeric-figure: ; --sp-tw-numeric-spacing: ; --sp-tw-numeric-fraction: ; --sp-tw-ring-inset: ; --sp-tw-ring-offset-width: 0px; --sp-tw-ring-offset-color: #fff; --sp-tw-ring-color: #3b82f680; --sp-tw-ring-offset-shadow: 0 0 #0000; --sp-tw-ring-shadow: 0 0 #0000; --sp-tw-shadow: 0 0 #0000; --sp-tw-shadow-colored: 0 0 #0000; --sp-tw-blur: ; --sp-tw-brightness: ; --sp-tw-contrast: ; --sp-tw-grayscale: ; --sp-tw-hue-rotate: ; --sp-tw-invert: ; --sp-tw-saturate: ; --sp-tw-sepia: ; --sp-tw-drop-shadow: ; --sp-tw-backdrop-blur: ; --sp-tw-backdrop-brightness: ; --sp-tw-backdrop-contrast: ; --sp-tw-backdrop-grayscale: ; --sp-tw-backdrop-hue-rotate: ; --sp-tw-backdrop-invert: ; --sp-tw-backdrop-opacity: ; --sp-tw-backdrop-saturate: ; --sp-tw-backdrop-sepia: ; --sp-tw-contain-size: ; --sp-tw-contain-layout: ; --sp-tw-contain-paint: ; --sp-tw-contain-style: ; margin: 0px; margin-block-start: 1.25rem; font-family: Lato, sans-serif; font-size: 14px;\"\u003eIn Auto-Switching Mode, the instrument automatically toggles between available wavelengths. When paired with a compatible EXFO power meter (such as the FOT-600 or FPM-600), the meter automatically recognises the active wavelength and applies the correct calibration parameters, reducing manual steps and minimising setup errors. An encrypted digital identifier is transmitted with the optical signal, allowing compatible instruments in the 300 and 600 series to detect the wavelength in use automatically. The source can also convey reference power level information to the receiving instrument to support distant referencing workflows.\u003c\/p\u003e\n\u003cp style=\"box-sizing: border-box; border-style: solid; border-width: 0px; border-color: rgb(217, 217, 217); -webkit-font-smoothing: antialiased; --sp-tw-border-spacing-x: 0; --sp-tw-border-spacing-y: 0; --sp-tw-translate-x: 0; --sp-tw-translate-y: 0; --sp-tw-rotate: 0; --sp-tw-skew-x: 0; --sp-tw-skew-y: 0; --sp-tw-scale-x: 1; --sp-tw-scale-y: 1; --sp-tw-pan-x: ; --sp-tw-pan-y: ; --sp-tw-pinch-zoom: ; --sp-tw-scroll-snap-strictness: proximity; --sp-tw-gradient-from-position: ; --sp-tw-gradient-via-position: ; --sp-tw-gradient-to-position: ; --sp-tw-ordinal: ; --sp-tw-slashed-zero: ; --sp-tw-numeric-figure: ; --sp-tw-numeric-spacing: ; --sp-tw-numeric-fraction: ; --sp-tw-ring-inset: ; --sp-tw-ring-offset-width: 0px; --sp-tw-ring-offset-color: #fff; --sp-tw-ring-color: #3b82f680; --sp-tw-ring-offset-shadow: 0 0 #0000; --sp-tw-ring-shadow: 0 0 #0000; --sp-tw-shadow: 0 0 #0000; --sp-tw-shadow-colored: 0 0 #0000; --sp-tw-blur: ; --sp-tw-brightness: ; --sp-tw-contrast: ; --sp-tw-grayscale: ; --sp-tw-hue-rotate: ; --sp-tw-invert: ; --sp-tw-saturate: ; --sp-tw-sepia: ; --sp-tw-drop-shadow: ; --sp-tw-backdrop-blur: ; --sp-tw-backdrop-brightness: ; --sp-tw-backdrop-contrast: ; --sp-tw-backdrop-grayscale: ; --sp-tw-backdrop-hue-rotate: ; --sp-tw-backdrop-invert: ; --sp-tw-backdrop-opacity: ; --sp-tw-backdrop-saturate: ; --sp-tw-backdrop-sepia: ; --sp-tw-contain-size: ; --sp-tw-contain-layout: ; --sp-tw-contain-paint: ; --sp-tw-contain-style: ; margin: 0px; margin-block-start: 1.25rem; font-family: Lato, sans-serif; font-size: 14px;\"\u003eThe FLS-600 features a backlit keypad and LCD for easy operation in dark environments such as cabinets, closets, and ducts. Built for field ruggedness, it is suited to the harshest test conditions. Tone generation at 270 Hz, 1 kHz, and 2 kHz supports fibre identification and tracing workflows.\u003c\/p\u003e\n\u003cp style=\"box-sizing: border-box; border-style: solid; border-width: 0px; border-color: rgb(217, 217, 217); -webkit-font-smoothing: antialiased; --sp-tw-border-spacing-x: 0; --sp-tw-border-spacing-y: 0; --sp-tw-translate-x: 0; --sp-tw-translate-y: 0; --sp-tw-rotate: 0; --sp-tw-skew-x: 0; --sp-tw-skew-y: 0; --sp-tw-scale-x: 1; --sp-tw-scale-y: 1; --sp-tw-pan-x: ; --sp-tw-pan-y: ; --sp-tw-pinch-zoom: ; --sp-tw-scroll-snap-strictness: proximity; --sp-tw-gradient-from-position: ; --sp-tw-gradient-via-position: ; --sp-tw-gradient-to-position: ; --sp-tw-ordinal: ; --sp-tw-slashed-zero: ; --sp-tw-numeric-figure: ; --sp-tw-numeric-spacing: ; --sp-tw-numeric-fraction: ; --sp-tw-ring-inset: ; --sp-tw-ring-offset-width: 0px; --sp-tw-ring-offset-color: #fff; --sp-tw-ring-color: #3b82f680; --sp-tw-ring-offset-shadow: 0 0 #0000; --sp-tw-ring-shadow: 0 0 #0000; --sp-tw-shadow: 0 0 #0000; --sp-tw-shadow-colored: 0 0 #0000; --sp-tw-blur: ; --sp-tw-brightness: ; --sp-tw-contrast: ; --sp-tw-grayscale: ; --sp-tw-hue-rotate: ; --sp-tw-invert: ; --sp-tw-saturate: ; --sp-tw-sepia: ; --sp-tw-drop-shadow: ; --sp-tw-backdrop-blur: ; --sp-tw-backdrop-brightness: ; --sp-tw-backdrop-contrast: ; --sp-tw-backdrop-grayscale: ; --sp-tw-backdrop-hue-rotate: ; --sp-tw-backdrop-invert: ; --sp-tw-backdrop-opacity: ; --sp-tw-backdrop-saturate: ; --sp-tw-backdrop-sepia: ; --sp-tw-contain-size: ; --sp-tw-contain-layout: ; --sp-tw-contain-paint: ; --sp-tw-contain-style: ; margin: 0px; margin-block-start: 1.25rem; font-family: Lato, sans-serif; font-size: 14px; margin-block-end: 0px !important;\"\u003e\u003cstrong\u003eFLS-600-234BL SPECIFICATIONS:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp style=\"box-sizing: border-box; border-style: solid; border-width: 0px; border-color: rgb(217, 217, 217); -webkit-font-smoothing: antialiased; --sp-tw-border-spacing-x: 0; --sp-tw-border-spacing-y: 0; --sp-tw-translate-x: 0; --sp-tw-translate-y: 0; --sp-tw-rotate: 0; --sp-tw-skew-x: 0; --sp-tw-skew-y: 0; --sp-tw-scale-x: 1; --sp-tw-scale-y: 1; --sp-tw-pan-x: ; --sp-tw-pan-y: ; --sp-tw-pinch-zoom: ; --sp-tw-scroll-snap-strictness: proximity; --sp-tw-gradient-from-position: ; --sp-tw-gradient-via-position: ; --sp-tw-gradient-to-position: ; --sp-tw-ordinal: ; --sp-tw-slashed-zero: ; --sp-tw-numeric-figure: ; --sp-tw-numeric-spacing: ; --sp-tw-numeric-fraction: ; --sp-tw-ring-inset: ; --sp-tw-ring-offset-width: 0px; --sp-tw-ring-offset-color: #fff; --sp-tw-ring-color: #3b82f680; --sp-tw-ring-offset-shadow: 0 0 #0000; --sp-tw-ring-shadow: 0 0 #0000; --sp-tw-shadow: 0 0 #0000; --sp-tw-shadow-colored: 0 0 #0000; --sp-tw-blur: ; --sp-tw-brightness: ; --sp-tw-contrast: ; --sp-tw-grayscale: ; --sp-tw-hue-rotate: ; --sp-tw-invert: ; --sp-tw-saturate: ; --sp-tw-sepia: ; --sp-tw-drop-shadow: ; --sp-tw-backdrop-blur: ; --sp-tw-backdrop-brightness: ; --sp-tw-backdrop-contrast: ; --sp-tw-backdrop-grayscale: ; --sp-tw-backdrop-hue-rotate: ; --sp-tw-backdrop-invert: ; --sp-tw-backdrop-opacity: ; --sp-tw-backdrop-saturate: ; --sp-tw-backdrop-sepia: ; --sp-tw-contain-size: ; --sp-tw-contain-layout: ; --sp-tw-contain-paint: ; --sp-tw-contain-style: ; margin: 0px; margin-block-start: 1.25rem; font-family: Lato, sans-serif; font-size: 14px; margin-block-end: 0px !important;\"\u003e\u003cstrong\u003eRefer to images\u003c\/strong\u003e\u003c\/p\u003e\n\u003c\/div\u003e","brand":"EXFO","offers":[{"title":"Default Title","offer_id":57433393267070,"sku":"8340+8338 5B01+6E02 NL01","price":335.75,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0574\/9492\/9575\/files\/57_8222a060-5572-4931-ad4a-c287c5e9df2e.jpg?v=1779095240","url":"https:\/\/www.ttinstruments.com\/products\/exfo-fls-600-light-source-fls-600-234bl-1310-1550-1625-nm-apc-sc","provider":"TT Instruments","version":"1.0","type":"link"}
