10MHz Reference Signal RF Link | GL7130
Global Foxcom’s GL7130 is a Sat-Light Gold Series optical link designed for transporting 10 MHz reference signals over fiber in satellite and wireless RF infrastructure. It converts incoming 10 MHz reference signals into optical transmission and reconverts them back to RF at the receiver side. The link is built for timing and reference distribution applications where stable signal quality, wide dynamic range, and compatibility with first-generation Sat-Light platforms are required.

The GL7130 is used in RF timing and reference distribution paths where a 10 MHz signal must be carried between equipment locations without relying on long coaxial runs. The transmitter converts the incoming reference signal into an optical signal, while the receiver restores the signal back to RF for use within satellite, wireless, and RF distribution systems.
The GL7130 is relevant when reference signal stability, platform compatibility, and deployment flexibility are key evaluation points. Its adjustable link gain, front-panel test port, multiple optical wavelength options, and support for 50 ohm or 75 ohm environments make it suitable for facilities planning upgrades, long-distance timing distribution, or integration with existing Sat-Light 7000 Series infrastructure.

When should the GL7130 be specified in an RF system design?
The GL7130 is specified when a 10 MHz reference signal needs to be transported between equipment locations over fiber. It is suitable for satellite and wireless infrastructure where reference signal delivery must remain stable across separated RF system areas.
How does the adjustable link gain support integration?
The adjustable gain ranges from -10db to +10db gives engineers control over RF output level during installation and calibration. This is useful when matching the reference signal level to downstream equipment requirements.
How does the GL7130 support existing Sat-Light infrastructure?
The GL7130 is compatible with first-generation Sat-Light products, making it suitable for facilities that need to extend or upgrade existing RF over Fiber infrastructure without changing the full platform architecture.
What should you consider when selecting the optical wavelength?
You should confirm required transmission distance, fiber availability, and system design before choosing 1310 nm, 1550 nm, or CWDM wavelength options. This ensures the optical configuration matches the planned reference signal path.
