Micro-optic couplers, built by coupling two lensed fiber collimators with an optical element in between, provide ultra-broad bandwidth (±200 nm), high polarization extinction ratio (>30 dB), excellent thermal stability, and allow integration of filters and polarizers, albeit at. Micro-optic couplers, built by coupling two lensed fiber collimators with an optical element in between, provide ultra-broad bandwidth (±200 nm), high polarization extinction ratio (>30 dB), excellent thermal stability, and allow integration of filters and polarizers, albeit at. We offer a full line of fiber optic couplers and splitters supporting SM, MM, PM, large core, and double-clad fibers across 300–2000 nm, with power handling up to 100 W and operating temperatures up to 300°C. Three fabrication methods are employed: fusion, micro-optics, and planar lightwave circuit. Thorlabs' compact, ultrastable FiberPort micropositioners provide an easy-to-use platform for coupling light into and out of optical fibers. Their compact size; repeatable, high-resolution alignment mechanism; high thermal stability*; and translation locking mechanisms (detailed in the Operation. Search our portfolio of Fiber Optics products for Low-temperature Applications and select your specifications. We offer a wide array of reliable and cost-effective products from standard solutions to custom designs. As a trusted provider of optical communication solutions, Weunion offers a range of high-quality optical fibers engineered for diverse thermal conditions—from frigid polar regions to scorching industrial settings. Fiber optic's advantages over copper cabling are well known immunity to EMI and RFI, low attenuation over long distances, high bandwidth capacity, smaller size and lower weight.
