Four-Core Fiber Fan-In/Fan-Out Device
The four-core fiber fan-in/fan-out (FI/FO) device is a precision optical interface for connecting four-core fiber (FCF) to standard single-mode fibers (SMFs). Advanced coupling technology enables bidirectional conversion between FCF and standard SMFs with ultralow insertion loss and extremely low crosstalk. It bridges FCF and standard SMF, supports spatially parallel transmission, and offers excellent thermal stability and high reliability.
