G.657B3 bend-insensitive single-mode fiber
Produced using a special optical fiber manufacturing process, this bend-insensitive single-mode fiber is designed for fiber to the home (FTTH), enterprise networks and other fiber-optic communications applications requiring an extremely small bend radius. Its performance comprehensively exceeds ITU-TG.657.B3 requirements. Very low additional bending loss at a 5mm bend radius meets installation needs under complex indoor and outdoor routing conditions, such as fiber to the home, overcoming additional bending loss caused by corners, jumper fastening and high cable tension to ensure stable communications-system operation. Applicable standards: meets and exceeds the relevant provisions of ITU-TG.657.B3 and IEC 60793-2-50 B6.b3, providing compatibility and matching with existing fiber networks for easier customer use and maintenance.

Electro-optic deflectors (EODs) are optical devices used to steer or deflect light beams by applying an electric field to a specialized optical crystal. Unlike mechanical beam steering systems that rely on moving mirrors, electro-optic deflectors enable high-speed, non-mechanical beam control with exceptional precision and responsiveness. They are widely used in laser scanning, optical communications, microscopy, laser printing, spectroscopy, and scientific research, where rapid and accurate laser beam positioning is essential.
