LONDON, U.K. -- PROTODEL International Ltd, a global leader in the development of fiber optic components, has introduced the smallest in-line fiber optic polarizer in the world.Half the size of the company’s most recently introduced high performance, all-fiber, in-line polarizer; this new product features a steel tube that is only 30mm in length and 3mm in diameter.This new specialized device is available in three configurations (SM/SM 30mm, SM/PM 40mm and PM/PM 50mm), and offers a high extinction ratio (> 50dB), with low insertion loss (<0.1 dB) and near zero back reflection (< -70dB).It has been designed with particular reference to the space-conscious needs of the defence and test and measurement markets, where size is important and input/output polarization is critical to ensure optimum operation. The company already supplies more than 50% of the world market for high performance, low-cost, fiber optic in-line polarizers and this latest addition to the ProtoDel product range is expected to further consolidate its leadership position.ProtoDel International Ltd.
