Mini RF over Fiber Transmitter & Receiver kit supporting a frequency range of 100Mhz to 4000Mhz (4Ghz) Functioning transparent RF fiber links
Using copper as a medium has a sizable limitation due to significant loss, hence why using fiber optic RF over Transmitter and Receivers solve the distance transport problem.
It is used in many RF over fiber applications like communications, defense systems, satellite L-band, S-band, GPS, WiMAX, cellular 3G, 4G and LTE signals.
DAS system linking the Base Station (BS) to single or multiple Remote Antenna Units (RAU)
The unit has SMA 50ohm electrical interfaces and FC/APC optical, base mode operates on 1310nm and supports distance of up to 20km over single mode fiber.
These units do NOT support Multimode fiber.
Customized units are also available for long haul distance or optical wavelength.
Fiber Optics provide several other significant network advantages, including simplified network design, ease of installation, and immunity from EMI/RFI and lightning.
Applications
IMPORTANT NOTE*** (it is very important to interface our unit with FC/APC - Angle Polished Connector to avoid any light reflections.
If your fiber is terminated with the SC, ST, FC /PC flat connector, you need to use an optical jumper from PC type to FC/APC for proper conversion.
F-RFoF-4GHZ-TX-XX RFoF -RF over fiber 4Ghz optical Transmitter
F-RFoF-4GHZ-RX-XX RFoF -RF over fiber 4Ghz optical Receiver
XX-distance in fiber and optical wavelenght, the base unit is 1310nm up to 20Km distance over single mode fiber
Custom 1550nm or CWDM or DWDM are avaialble via request
