Description

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.
KEY FEATURES
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
RF Specifications
