Product details

Introduction

VEIVOT's single mode dual window couplers 1x2 and 2x2 provide very low insertion loss, low polarization dependence, and excellent environmental stability. The precise coupling ratio ranges from 50/50 to 1/99, and the fiber types 250um bare fiber, 3mm and 900um loose tube fiber have very tight uniformity within the wide wavelength range of 1310nm, 1490nm and 1550nm windows. Single mode dual window couplers have extensive power allocation and monitoring functions in various optical communication systems.
