衛(wèi)星通信中,點到點的天線可以通過此設(shè)備將射頻信號轉(zhuǎn)為光信號,通過光纖連接*幾米到幾千米的控制室外。廣播信號也可以將RF信號轉(zhuǎn)為光信號通過光纖傳輸。雷達(dá)系統(tǒng)可以通過此方式將雷達(dá)天線和信號室進(jìn)行遠(yuǎn)距離連接。射頻光模塊根據(jù)帶寬的不同,有8GHz,15GHz,20GHz不同射頻帶寬的產(chǎn)品,另有3GHz, 2.4GHz, 1.5GHz等低頻段,根據(jù)需要,可選擇單向和雙向傳輸系統(tǒng)。
The RF over fiber transmission module ROF400M designed for RF/wireless signal transmission over long distance, which overcome the problem of high loss when the RF/wireless signal transmit over coaxial cable or free space.
