Because of large core multimode fibers and connector tolerances, transmission variation can only be minimized using a pigtailed version of 1x1 fiber-optic rotary joint. The pigtailed patch cords are made from 0.37 or 0.57 NA, 200 or 400 µm diameter optical fiber with a lightweight metal jacket and FC connectors. The fixed input patch cord measures between 1 and 2 meters in its standard version, while the output rotating patch cord is 0.15 meters long. Different length fiber-optic patch cords can be connected to the output using an FC\/FC mating adapter.\u003cbr\u003e\u003cbr\u003eThis is an improved version of our \u003ca href=\"\/products\/1x1-fiber-optic-rotary-joints-pigtailed\" target=\"_blank\" rel=\"noopener\"\u003ePigtailed 1x1 Fiber-optic Rotary Joint\u003c\/a\u003e with better mechanical stability.  It is important to note that the outer diameter is slightly larger than the original version, and requires the holder to have an aperture of 19 mm diameter.\u003cbr\u003e\u003c\/p\u003e","brand":"Doric Lenses Inc.","offers":[{"title":"Default Title","offer_id":47933645717746,"sku":null,"price":0.0,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0771\/1916\/0562\/files\/FRJ_1x1_PT19.png?v=1787318793"},{"product_id":"2x2-pigtailed-fiber-optic-rotary-joint","title":"2x2 Pigtailed Fiber-optic Rotary Joint","description":"\u003cp\u003eThe Pigtailed 2x2 Fiber-optic Rotary Joints have 2 optical channels with static side pigtailed with 1m long FC-connectorized optical fibers.

The motorized assistance allows its frictionless rotation. The sensor within the rotary joint detects torsion in a fiber-optic tether to a moving animal, turns the rotor accordingly, and lets the animal move without discomfort. These rotary joints have 2 optical channels with static side pigtailed with 1m long FC-connectorized optical fibers. Due to the space constriction with 2 FC connectors side by side, we have chosen to use two M3 receptacles on the rotating side. The patch cords have a 200 or 400 μm core, 0.37 or 0.57 NA optical fibers on both sides for maximum reliability (customization of fibers are possible on request).
