GPS Over Fiber
​Intelibs GPS over Fiber Systems transmit GPS signal over Fiber Optic cables. The system delivers GPS signal to remote locations where the GPS signal may not reach due to significant signal loss or limited coax cable runs by due to building structural constraints.​

Dramatic Cost Savings From a Scalable System Architecture
​​
​Intelibs GPS over Fiber systems are designed to lower total cost of ownership (TCO) through innovative features and scalable architecture. By incorporating optional Power-over-Ethernet (PoE) models, our system can save up to 50% of TCO by reducing the need for electrical construction, utility metering, and permit acquisition. For large-scale network deployments with multi-room GPS receiver configurations, the scalable architecture—including Fiber Distribution Units (FDU) and Coax Distribution Units (CDU)—further enhances efficiency and can reduce TCO by more than five times compared to traditional solutions.
FRONT END UNIT (FEU)
Connects to the GPS antenna on the roof, the FEU converts GPS radio signal to optical waves and transfers to the BEU. Available in four-GPS-port or two-port (‘compact’) configuration, both enclosed in NEMA-4 enclosures.
​
BACK END UNIT (BEU)
Located next to the GPS receiver equipment (e.g. BTS or Server), the BEU converts optical wave formed GPS signal to the original radio frequency and forwards it over coax cable to the GPS receiver
​
FIBER DISTRIBUTION UNIT (FDU)
As an optional unit for the large scale installation, FDU distributes the optical waves of GPS signal from a signal FEU to multiple BEU’s.
​
SINGLE-PORT FRONT-END UNIT (sFEU)
Similar to the FEU, the sFEU connects to the GPS antenna and is Intelibs most compact GPS-to-Optical signal conversion equipment. Intelibs Single-Port GPS over Fiber product line provides the most compact and cost-effective GPS transport solution.
​
SINGLE-PORT BACK-END UNIT (sBEU)
Enclosed in a compact body, the sBEU receives the optical signal and converts it back to GPS signal. Unit can be powered directly from GPS receiver using 5Vdc over coax connection.
​
MODULAR BACK-END UNIT (mBEU)
The Modular Back-End Unit (mBEU) supports up-to two optical-to-RF converter modules and equipped with remote-monitoring capabilities.

System Configurations
Product Features
Network Equipment Building Standards (NEBS) Level 3 Certified: Intelibs GPS over Fiber systems have been certified to NEBS Level 3, that is qualified for the carrier to install the systems inside the Central Office (CO) as well as mission critical network facility. (note: NEBS Level 3 is a Telco industry standard required for equipment installation of the Central Office).
Power over Ethernet: Intelibs GPS over Fiber systems built in Power over Ethernet (PoE) electrical construction on the roof or remote location from the BEU. The FEU powered by PoE from the remote equipment room with the back-up generator or battery is operated in highly reliable and safe power service as well as easy maintenance.
High Performance RF filter: Intelibs GPS over Fiber Front End Unit (FEU) employs with proprietary RF filter rejecting interference signal from outside the GPS radio frequency.
Scalable and Redundant System Architecture: Scalable architecture with FDU and CDU enable the GPS signal from a single FEU to be served in multiple locations where the service providers place multiple GPS receiver units within the central office or data center. Hot and Standby redundant architecture assures the system operation with full redundancy.
SNMP based remote monitoring and management
Remote Monitoring Capability: Intelibs GPS over Fiber system is equipped with remote monitoring capabilities via Web/SNMP (Simple Network Management Protocol)-based portal, enabling real-time monitoring of system status including signal strength and GPS signal reception in the FEU.
