FOI Fiber Optic Interface
FOI Fiber Optic Interface
Bird Technologies - The RF Experts


The Fiber Optic Interface (FOI) converts the RF signals into modulated laser light. The module can be equipped with or without WDM technology as options. The unit is ultra-wide band and handles multiple bands or operators as required.

— Up to 4 remote units on a single WDM fiber
— Supervision of signal levels and alarms
— A large selection of wavelengths possible
— Ethernet over fiber to remote unit
— Up to 25 km fiber possible
— With or without WDM
— Test ports for uplink and downlink signal monitoring
— RoHS compliant
