Analog radio-frequency-over-fiber modules (RFoF) convert high-frequency RF signals such as GNSS signals into fiber-optic signals and back again. An RFoF signal conversion kit comprises a fiber-optic transmitter that converts the RF signal into a fiber-optic signal, and a receiver unit converts the fiber-optic signal back into RF signals.

The two converter devices are connected via a single-mode fiber-optic cable, which is not included with the product.

Meinberg RFoF conversion kits are suitable for extending the range of Meinberg GNSS antenna-to-receiver connections. In particular, the following Meinberg GNSS-synchronized reference clocks are suitable for use with an RFoF fiber-optic signal conversion kit:

• LANTIME M-Series systems with GNS or GNM-type reference clocks
• SyncFire systems with GNS-type reference clocks
• microSync systems with GNS-type reference clocks
• IMS-GNS reference clock modules (IMS-GNS181 / IMS-GNS182 / IMS-GNS183)
• IMS-GNM reference clock modules (IMS-GNM181)
• IMS-GXL reference clock modules (IMS-GXL183)
• GNS/D(A)HS receivers (GNS183/D(A)HS / GNS181/D(A)HS)
• PCI Express GNS-type clock cards (GNS183PEX / GNS181PEX)
