An optical splitter is a crucial passive fiber optic device that splits and combines optical signals. It can distribute the optical energy transmitted through a single fiber to two or more fibers in a predetermined ratio or combine the optical energy from multiple fibers into one fiber. Bare fiber splitter is relatively fragile on fiber protection and need a complete protection design on carrying box body and device. T PON standards such as GPON, XGS-PON and new 25 and 50G standards. Claims filed after the date of filing of the application/after the date of receipt of the divisional application (Rule 68(4) EPC).
