1310B-HP-V0 Bend-Insensitive Single-Mode Fiber
Coherent/Nufern’s 1310B-HP-V0 (900um tight-buffered) bend-insensitive selected-cutoff specialty single-mode fiber operates at 1310nm and 1550nm, with excellent bend insensitivity at 1550nm. A 900um V-0-grade flame-retardant PVDF secondary coating meets UL94. Twelve standard colors and custom printed markings are available. The tight buffer operates from -40 to +85℃ without shrinkage. Superior consistency and core/cladding concentricity meet tighter specifications than industry standards, including tighter second-order-mode cutoff tolerances. Small bend radii suit miniaturized fiber-device packaging. Proof testing above 200kpsi improves device reliability, and strict specifications support higher manufacturing yield and lower cost.

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.
For low-frequency RF, electromagnetic testing and power combining systems, conventional resistive power dividers bring high insertion loss, while standard directional couplers cannot provide equal-amplitude signals with 180° phase shift.
