Analog RFoF optical Transmitter is used to convert RF signals to optical signals that can be sent and carried over long distances of fiber optic cable.
The Optical Receiver converts them back to an RF signal. The two units are connected through 1 single mode fiber up to 40Km.
RF over Fiber modules (RFoF) are commonly used in L-band, S-band satellite, radio telescopes, RF antennas distribution, broadcasting audio, and video, timing synchronization and GPS applications and other telecommunications.
It's very easy and cost effective to extend a signal from any antenna, Modulator or RF instrument, point to point or multipoint to multipoint using fiber optic splitters.
Applications
IMPORTANT NOTE*** (It is very important to interface our unit with the SC/APC - Angle Polished Connector to avoid any light reflections.)
If your fiber is terminated with the SC, ST, or FC/PC flat connector, you need to use an optical jumper from PC type to SC/APC for proper conversion.

The base models operate at 1310 nm.
We can supply CWDM wavelengths upon request—special order, quote required.
For CWDM variants, the part number ends with -XX indicating the wavelength (e.g., -1510, -1530, -1550, -1570, -1590, -1610 nm). -Examle : F-RFoF-6GHZ-LNA-TX/RX-1510nm

OP |
O |
Received Optical Power Monitor. The voltage of OP is explained below. |
The OP voltage (Vop, unit: V) VS received optical power ( Pop, unit: mW) follows the formula:
Vop? D*Pop
The D factor is defined as the detection factor in V/mW units. The typical range of D is from 0.25 V/mW to 0.5 V/mW. For example, D=0.375 V/mW, the OP voltage (Vop) VS received optical power (Pop) is as shown in the table below:

The user can input the known optical power Pop and detect the Vop voltage, and then calculate the approximate value of the D factor of an optical receiver using the formula Vop? D*Pop. In this case, the obtained D factor and Vop can be used to estimate the optical power received by the optical receiver in practical applications. Notes:

6 Ch L-Band Satellite Over single Fiber Extender Transmitter and Receiver 54-3000Mhz -CWDM
6-channel Satellite LNB fiber-optic Extender. 6 LNB satellite TV antenna feed over fiber-optic transmission system with internal CWDM optics. Ideal for point-to-point transport or for small-scale (Level 1 only) LTTH distribution systems with 32 or fewer optical receivers. Supports ATSC feed from a local off-air antenna, 54-3000mHz. Best satellite distribution system for MDU - Multi-Dwelling Unit
GPS - GNSS Over Fiber In-Building Distribution System - up to 32 remote unit
The GPS / GNSS Over Fiber In-Building Distribution System is designed to extend GPS and GNSS satellite signals into indoor and underground areas where normal satellite reception is weak or unavailable. The system uses an outdoor GNSS antenna, a 1RU master unit, fiber optic links, and remote indoor antenna units to provide GNSS coverage inside buildings, parking garages, tunnels, warehouses, transportation centers, and public safety facilities. The master unit receives the GNSS signal and distributes it over fiber to multiple remote units. Each remote unit rebroadcasts the GNSS signal in its local area, allowing GPS-enabled devices to receive positioning information even in GNSS shadow areas. The system supports L1 and L5 bands, up to 10 km fiber transmission, and multiple remote units for large multi-zone installations.
